Title: Photo electric conversion unit using charge storage type photo electric element array
Inventor: SHIROKAZU HIROSHI
IPC: H04N5/335
Filed: 1978-12-22
Abstract: PURPOSE: To improve the frequency response of photo electric element, by control in response to the output voltage of photo electric element for the charge storage time of charge storage type photo electric element array.  
     CONSTITUTION: The output voltage of the charge storage element 100 performing photo-electric conversion is compared for the average value with the reference voltage 600a, and inputted to the error detection circuit 600 outputting the voltage of difference. The difference voltage outputted from the error detection circuit 600 is made to the frequency F with the V-F converter 700 performing frequency conversion exponentially to the input voltage. Since the charge storage time is controlled for the photo electric element with the frequency F, the amplitude of AC output of the pick up circuit 400 can almost be kept constant. Further, since the characteristics of this control system is exponential, the response characteristics can be determined independently of the frequency and the response can be kept constant.

Title: Braking hydraulic pressure controller
Inventor: KUBOTA HITOSHI
IPC: B60T8/30
Filed: 1984-07-31
Abstract: PURPOSE:To prevent rear wheels from locking so early even if a load is one-sided to in front and in the rear of a car, by setting desire braking hydraulic pressure according to rear-wheel load, while compensating the said desired braking hydraulic pressure to the operating delay of a solenoid valve controlling confined pressure. CONSTITUTION:A hydraulic pressure setting device 75 of a microcomputer 73 outputs a desired braking hydraulic pressure signal SC on the basis of front and rear wheel load signals Sp1 and Sp2 of front and rear wheel load detecting devices 71a and 72b. A compensation device 77 calculates an inlet pressure boost velocity from an inlet hydraulic pressure signal SG out of a hydraulic pressure detecting device 81, and according to this operational result, compensates the said desired braking pressure signal SC, outputting a compensated desired braking hydraulic pressure signal Scm. A comparing device 79 closes a solenoid valve 21 when an inlet hydraulic pressure Pm becomes larger than the compensated desired braking hydraulic pressure. As a result, with confined pressure in an enclosure chamber 51, set load of a spring 63 is thus set to a proper value.

Title: Disc brake housing assembly
Inventor: UEIN HARU GARETSUTO
IPC: F16D65/18
Filed: 1979-12-10
Abstract: A housing assembly for a wedge type disc brake in which the wedge actuator is housed in a radially disposed aluminum housing member which is clamped between the inboard end of a ferrous caliper housing member and a ferrous end plate by axial bolts passing through the end plate and the aluminum housing member for threaded engagement with bores in the inboard end of the caliper housing. The inboard face of the aluminum housing member has an opening opposite the wedge actuator which is closed by the end plate so that the inboard rollers of the roller bearing assembly interconnecting the wedge actuator and the push rod bear directly on the outboard face of the end plate. The braking force generated at the interface of the wedge actuator and the push rod is thus transferred to the end plate and absorbed by tensioning of the bolts, thereby relieving the aluminum housing of any significant tensile loading.

Title: Plasma display panel
Inventor: KANI AKIRA
IPC: H01J17/49
Filed: 1992-05-28
Abstract: PURPOSE:To avoid the occurrence of locally concentrated discharge by composing a cathode within one cell of a low resistance part having a specific value and a high resistance part and making the area of the high resistance part larger than that of the low resistance part. CONSTITUTION:A cathode 3 within one cell is composed of two parts including a low resistance part and a high resistance part and the area of the high resistance part is made larger than that of the resistance part. The sheet resistor of the low resistance part is formed to be not more than 10OMEGA and that of the high resistance part is formed to be above 10kOMEGA, and both parts are shaped in continuous form. And when a discharge current is increased, glow discharge is initiated in the low resistance part at first and sequentially the discharge is expanded into the high resistance part. When the discharge current reaches a current value which is determined by a voltage applied to a tube, the expansion of discharge is not more than the area of the low resistance part, and when cathode materials have a high gamma value, the discharge is locally concentrated, so that the runaway of current occurs even in the case where they are driven by the same voltage. Therefore, the area of the high resistance part is made larger than that of the low resistance part, thereby making it feasible to avoid the local concentration of discharge even when the gamma value of the cathode materials is high or the pressure of discharge gas is high.

Abstract: PURPOSE:To make it possible to embody energy saving by installing a space for ventilation between an old outer wall and a new outer wall. CONSTITUTION:A new outer wall 1 is installed on an old outer wall of a building skeleton 13 in order to form a ventilation space by way of a support material. It is also possible to house piping or a wiring 10 in this space. Main plant equipment 12 installed on a rooftop is connected to indoor equipment 12a, 12b and 12c by way of the piping or the wiring 10.

The air is discharged from a space between an old coping 15 and a new coping 16. This construction makes it possible to prevent the heat absorbed from a wall surface from entering indoors in summer and prevent the generation of the air flow by shutting down the air vent in winter. It is also possible to control the air vent in conformity with room temperature in spring and fall as well.

Abstract: PURPOSE:To reduce the man-hour for adhesion in a field assembling construction by applying an adhesive, which is charged preliminarily in the unhardened state, to the inside of a small-diameter hole of a terminal member and starting to harden the adhesive after an optical fiber is inserted to the small-diameter hole. CONSTITUTION:A small-diameter hole 2 to which an optical fiber 6 should be fixed is provided in the center of a terminal member 1 of an optical connector plug. An unhardened adhesive 3 is charged to the inside of the small-diameter hole 2. For example, a polycondensation-type adhesive which starts the hardening reaction when contacting with moisture in air is used as this adhesive 3. For the purpose of keeping the adhesive 3 unhardened, both ends of the small-diameter hole 2 are closed by airtight seals 4 and 5 to prevent the adhesive 3 from contacting with the outside air. In case that the optical fiber 6 is adhered to the terminal member 1, seals 4 and 5 are removed from the terminal member 1 to insert the optical fiber 6 to the terminal member 1, and they are stuck to each other by hardening of the adhesive 3.
