Title: Solid-state image pickup element for color camera
Inventor: FUJII MUNEAKI
IPC: H04N9/04
Filed: 1985-07-08
Abstract: PURPOSE:To always perform the right adjustment of the while balance of an object accommodating a detecting part for a white balance adjustment within a package where a solid-state image pickup part is accommodated. CONSTITUTION:Rays of light 11 made incident on through a lens 12 is made incident on a solid-state image pickup part 21 within a solid-state image pickup element 24, and simultaneously on a detecting part 22 for the white balance. The correcting information of R, G or B, or each of chrominance component ingredients R-Y or B-Y corresponded to the color temperature of the rays of light made incident on is outputted by the detecting part 22. The correcting information is impressed on a gain adjusting part 14 through a comparing amplification part 19 and the white balance of each chrominance component ingredient is adjusted, and it is outputted to an output terminal 16 as a color compound signal through an image processing part 15. Thereby, a correct white balance can be obtained, even when the color temperature at the peripheral of the object is different from the color temperature at the place where the camera is installed.

Title: Display device
Inventor: SHIMIZU MASATOSHI
IPC: G09G3/20
Filed: 1988-06-17
Abstract: PURPOSE:To discriminate the difference of color information on a monochromatic display as a difference between two stages of brightness by combining an ON-OFF circuit for each frame with a color signal selecting circuit. CONSTITUTION:A switch circuit 120 is selected by a user to select a color signal to be displayed. For example, when only a switch 122 is turned on, a G signal (green) is displayed. When a switch 124 is also turned on in combination, the part of an R signal (red) is displayed while turned on and off at intervals of one frame, so the part of red illuminates with brightness a half as large as that of the part of green. When a switch 121 is further turned on, an R signal is outputted as a data signal at all times, so the function for tuning on and off the R signal at intervals of one frame is made ineffective. Consequently, an artificially two-gradation display is made.

Title: Speed change controller in power shift changing device
Inventor: NISHIKAWA FUMIAKI
IPC: F16H63/02
Filed: 1987-06-16
Abstract: PURPOSE:To obtain arbitrary clutch pressing pressure in response to the turned angle of a speed changing lever by detecting the turned angle of the speed changing lever by means of a potentiometer, and controlling a current for operating a solenoid proportioned pressure reducing valve on the basis of the detected value. CONSTITUTION:When a vehicle, for example, advances at a slight speed, a speed changing lever 45 is turned to a low speed side, and then the turned angle thereof is detected by means of a potentiometer 46 so that, on the basis of the detected value, a control unit 48 reduces a current value to a solenoid proportioned pressure reducing valve 44. And, an oil pressure is kept to be low so that a clutch 24 for reverse speed change is maintained at the half-clutched state, thereby enabling advance at a slight speed. Meanwhile, at the time of advancing on an ascending slope or the like, the speed changing lever 45 is turned to a high speed side, the control unit 48 enlarges the current value to the solenoid proportioned pressure reducing valve 44 in response to the value detected by the potentiometer 46. The oil pressure passing through a reverse control valve 49 is increased for a short period, thereby shortening the period when the clutch 24 is at the half-clutched state so as to perform prompt clutch engagement. Therefore, pressure-rise can be optimally controlled.

Title: Vehicle brake hydraulic pressure control device
Inventor: KUSANO AKIHITO
IPC: B60T7/06
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To quickly impart a brake hydraulic pressure to a wheel brake in a defect in a stroke simulator by constituting a control means so as to close a second opening and closing valve on the essential condition that the stroke of a brake pedal or master cylinder exceeds a prescribed stroke. SOLUTION: When the liquid chamber PC3 of a stroke simulator SM is defective, a simulator cur valve SC is set to a closed position since the stroke of a brake pedal BP exceeds a prescribed stroke corresponding to the maximum stroke of the simulator SM. Since the maximum stroke of the simulator SM is set so as to be smaller than the stroke corresponding to the maximum housing liquid quantity containable in the second pressure chamber PC2 of a master cylinder MC, the master cylinder hydraulic pressure and, in its turn, the brake hydraulic pressure of all wheels can be suddenly raised before the capacity of the second pressure chamber PC2 of the master cylinder MC becomes 0.

Title: Free electrolyte type fuel cell
Inventor: KONDO KO
IPC: H01M8/02
Filed: 1987-06-16
Abstract: PURPOSE:To make the reaction area of electro-chemical reaction equal to or larger than the direct contact area of an electrolyte with an electrode via an electrolyte chamber by inserting a porous membrane between an electrolyte chamber spacer inserted in the chamber and the electrode. CONSTITUTION:A porous membrane 18 is inserted between electrodes 1 and 2, and an electrolyte chamber spacer 5, thereby causing the infiltration of an electrolyte through the membrane 18 and the cell reaction thereof even at a position locally in contact with the surface of the spacer 5 opposing a pair of the electrodes 1 and 2. As a result, the effective reaction area of the cell reaction becomes large and osmotic pressure due to the infiltration of the electrolyte through the membrane 18 antagonizes the pressure of reaction gas. Hence, the porous membrane 18 forms a BPB (bubble pressure barrier) retaining the reaction gas pressure.

Title: Target for measuring point
Inventor: KASAI SHINICHI
IPC: G01C15/06
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To readily and accurately measure a gravity position of a target section without executing image processing such as ellipse approximation by a constitution wherein the target section is formed in a sphere. SOLUTION: Each of targets A-C for measuring a point is attached to each measuring point on a structure member 1 in order to execute three-dimensional measurement. Each of the targets A, B, C is comprised of a leg section 4 attached to the measuring point, a spherical target section 5 supported by the leg section 4 and a screen section 6 provided to the rear side of the target section 5. The target section 5 is formed in the sphere having a specific size, e.g. a diameter of 40mm and the surface is coated with white color. Since the target section 5 is formed in the sphere, the image of the target section 5 becomes a circle irrespective of the imaging angle even when the target 5 is imaged by a CCD camera 3 from any angle. As a result, it is possible to readily and accurately obtain the gravity position of the target section 5 without executing the image processing such as ellipse approximation.

Title: Semiconductor memory
Inventor: IWASE HIROSHI
IPC: G11C11/34
Filed: 1982-08-30
Abstract: PURPOSE:To improve the yield of a nondefective product, by using the semiconductor memory as a memory that has 1/2 capacity of an inhereut capacity even though a defect exists anywhere among an address buffer circuit, an address decoder and a memory cell respectively, i.e. extending from the address buffer circuit to the memory cell. CONSTITUTION:For an address buffer 12n-1 corresponding to a bit ''n-1'' generated by a defective memory cell, F11=1 is set to avoid selection of a region of An-1=0. As a result, the transmission line of the address data An-1 is changed. Thus it seems as if an address data An were fixed when viewed from outside even though the output of the buffer 12n-1 corresponding to An-1 is fixed. Therefore no pin 11n is used in this case to obtain a memory which has 1/2 inherent storage capacity.

Title: Reset circuit for forward converter having active clamp circuit
Inventor: TAKEGAMI EIJI
IPC: H02M3/28
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To suppress overvoltage applied to a switch element while preventing saturation of a transformer by automatically turning on a switch element connected in parallel with a capacitor when a main switch element is turned off in order to stop a circuit. SOLUTION: A series circuit of a DC power supply 5 and a main switch element 3 is connected across the primary coil 12 of a transformer 4. Furthermore, a series circuit of a capacitor 6 and a parallel circuit of a switch element 8 and a diode 7 is connected in parallel with the primary coil to constitute an active clamp circuit, and a switch element 9 connected in parallel with the capacitor 6 forms a reset circuit. Since the switch element 9 in the reset circuit is turned on with a circuit stop signal, energy stored in the capacitor 6 or circulated from the secondary circuit is discharged. Consequently, overvoltage being applied to the switch element can be suppressed while preventing saturation of the transformer.

Title: Device and method for inspection
Inventor: UCHIDA JUN
IPC: G06T7/00
Filed: 1995-06-16
Abstract: PURPOSE: To accurately inspect and discriminate an article by resetting the synchronizing signal of a video camera with a signal synchronized with the movement of a subject and driving a stroboscopic light emission unit. CONSTITUTION: A field signal FLD and the camera synchronizing signal VD are always supplied from the video camera 15 to a video signal processing board 24, but when a reset signal is supplied, the signals FLD and VD are reset and synchronized with an input instruction signal TP. A trigger substrate 23 supplies the reset signal RP to the video processing board 24 and then supplies an image input instruction signal ITP to a digital input/output part 25 a specific short time later, namely, after a time shorter than one cycle of the camera synchronizing signal VD, thereby supplying a stroboscopic light emission instruction signal SP to a stroboscopic unit driving part 17. The stroboscopic light emission unit 16, therefore, emits light. Consequently, a video signal ID which is synchronized with the movement or XY coordinates of the subject can be obtained.

Title: Joint cross for universal joint assembly
Inventor: JAMES T REYNOLDS
IPC: F16D3/41
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a structure for surely holding a bearing cup onto each trunnion of a joint cross for an universal joint prior to its assembly onto a vehicle. SOLUTION: A ring shaped upheaval part 12b for determining an increased outer diameter, is formed in each trunnion 12 of a joint cross for an universal joint. A bearing cup is mounted to each trunnion in such a way that it can be rotated. Each rigid dust cover 30 is mounted to each bearing cup. Each dust cover 30 includes one portion extended inwardly for determining its inner diameter. The inner diameter determined by the inwardly extended portion 30b of each dust cover 30, is smaller than the outer diameter determined by each ring shaped upheaval part 12b. Namely, during installation, the inwardly extended portion 30b of each dust cover 30 formed in each trunnion 12 goes across the upheaval part 12b, and it is thereby snapped over. Thus as mentioned above, each bearing cup is surely held onto each trunnion 12 during transportation.

IPC: C21D9/08
Filed: 1982-09-01
Abstract: PURPOSE:To accurately heat treat a seamed part, by performing the automatical movement of an inductor for induction heating the welded part of a pipe being carried in the step of manufacturing an electric seamed pipe or the like on the basis of a signal from a seam sensor. CONSTITUTION:A pipe 1a running on supporting-carrying rolls 11 successively passes through a guide roll 2, a welder 3 and inductors 5a-5n. Seam sensors 4, 4a detect the position of a seam 9 along the circumferential direction of the pipe at their positions. In general, the twisting angle theta of the pipe based on the perpendicular upper part is detected and sent to a function generator 8. The generator 8 indicates theta as the quadratic function of x using the position of the roll 2 as an origin and the center of the pipe along the direction of a carrying line as an axis x, to function-indicate the position of the seam 9. This signal 12 is compared with a feedback signal 10 representing the position of the inductor by the position controller 7 of a seam-tracking means 14 to send a driving signal to a persuit driving means 6 on the basis of the resulting deviation. Thus, the inductor 5 is driven by a mechanism 6.

Title: Fine pulverization of difficultly meltable polymer
Inventor: NAKA KIYOMI
IPC: C08J3/12
Filed: 1995-05-16
Abstract: PURPOSE: To effectively finely pulverize a highly tough difficultly meltable polymer at a higher temperature than the ordinary temperature by a dry mechanical method utilizing a shear force. CONSTITUTION: A difficultly meltable polymer is added to an easily meltable polymer. If necessary, the obtained mixture is heated to melt only the easily meltable polymer and subsequently cooled to obtain the composite product wherein both the polymers are tightly adhered to each other. The mixture or the composite product is subjected to a shear-pulverization treatment using a biaxial kneading extruder, a stone mill type kneading extruder, etc., in a solid phase state. The finely pulverization method facilitates the shear pulverization which is difficult for the difficultly meltable polymer alone, and enables to prevent powder coagulation which is easily concurred. The finely pulverization method enables to reduce the consumption of energy and profitably obtain the fine powder in comparison with the conventional freezing impact-pulverizing method.
