IPC: H04N1/19
Filed: 1984-11-30
Abstract: PURPOSE:To incorporate a sensor and a thin film optical guide path by providing plural image pickup elements and a thin film optical waveguide array coupled to the image pickup elements so as to utilize the thin film optical guide path for the propagation of light to the image pickup elements thereby eliminating the need for focus adjustment of an image pickup optical system. CONSTITUTION:Plural strip lines 6 are formed to a base 5, the thin film optical guide path 7 is formed corresponding to a strip line 6 and a reception section of the image pickup element 2 and an irradiated outlet of the optical guide path 7 are matched. An incident inlet of the optical guide path 7 and a red face 1 are parted by a minute gap (d) so as to prevent a reflected light on the read face 1 from being made incident on the adjacent optical guide path 7 and the brightness distribution of the read face is read by a line sensor comprising the image pickup element 2 without decreasing the resolution. Then the adjustment of the focus of the image pickup optical system is made not required to incorporate the sensor and the optical guide path.

Title: Lead frame for semiconductor device
Inventor: TSUNODA YOICHI
IPC: H01L23/50
Filed: 1989-09-28
Abstract: PURPOSE:To prevent the generation of needle-shaped shaving of plating resulting from the protrusion of plating so as to prevent accidents such as short, etc., and improve productivity and quality by putting it in such structure that the width of the outer lead inside a tie bar part is wider than the width of the outer lead outside the tie bar part. CONSTITUTION:In the outer lead 3 of a lead frame, the width of the outer lead 3a inside a tie bar part 4 is made wider than that of the outer lead 3b outside the tie bar part. For this reason, the plating applied on the outer lead 3 is crushed at the time of sealing with resin, and juts out to its side and the protrusion 5 of plating is formed, but since the jutted plating does not contact with a tie bar punch at the time of tie bar cutting in a post-charge process, the protrusion of the plating is not shaved off, and it has an effect of preventing the shortage between leads by needle-shaped shaving.

Filed: 1987-10-12
Abstract: PURPOSE:To contrive to raise a critical temperature of superconductivity, having a specific composition wherein Ba of Ba2YCu3O6+y is partially replaced with Cs. CONSTITUTION:The superconducting material has a composition comprising Ba2-xCsxYCu3O6+y (with the proviso that 0<x<=0.5, 0<y<=1). Since a compound having the composition has higher a critical temperature of superconductivity than that of Ba2YCu3O6+y, is readily synthesized and has excellent reproducibility of superconductivity, the compound is widely usable as a superconducting material. The compound of Ba2-xCsxYCu3O6+y is produced by weighing BaCO3, Cs2CO3, Y2O3 and CuO in the molar ratio of (2-x):x/2:1/2:3, blending the compounds and calcining the blend at about 800 deg.C for 12hr in oxygen. The calcined material is burnt at about 920 deg.C for about 30hr in oxygen.

IPC: E03D9/08
Filed: 1992-09-24
Abstract: PURPOSE:To reduce a load on a shaft when any backlash is produced between a gear means and a nozzle by providing an elastic member which is always made in contact with the gear means around the outer periphery of a rotation transmission means. CONSTITUTION:An elastic member 15 is fixed to the outer periphery of a pin 14 fixed to a shaft 12 of a motor 11, and it is fixed to an inner wall part 13d of a gear means 13 in which a second through hole 13c is formed so that they are always made in contact with each other. The shaft 12 is rotated by linking with a speed reducer mechanism in the motor 10 to cause the pin 14 to rotate the gear means 13. When any backlash is produced between the external gear teeth 13a of the gear means 13 and external gear teeth 6a of a nozzle 6, a load to be applied on the gear means 13 is absorbed by the elastic member 15, and a load to be given to the shaft 12 is reduced.

Abstract: PROBLEM TO BE SOLVED: To easily and quantitatively evaluate the formation of an object to be inspected such as a nonwoven fabric or the like so as to coincide with sensation of a person, by taking the image of the reflected light or transmitted light of an object to be inspected, extracting a plurality of characteristic quantities from the taken image, and inspecting the formation of the object to be inspected from a plurality of the extracted characteristic quantities. SOLUTION: An object 10 to be inspected such as a nonwoven fabric or the like is irradiated with the light from a luminaire 20, and reflected light is taken in by a CCD camera 30. An image processing and operating apparatus 40 operates and extracts a plurality of characteristic quantities from the image of the object 10 to be inspected taken by the CCD camera 30. A formation index operating and processing part operates a formation index on the basis of the brightness, uniformity and rough density operated by a brightness operating and processing part, a uniformity operating and processing part and a rough density operating and processing part. Herein, since a center-of-gravity method is used as a conclusion operation method, the changeover of an evaluation formula due to a formation degree can be smoothly performed. An operated formation index is displayed on a display apparatus.  Since the formation measurement corresponding to the change of the viewpoint of a person due to the formation degree is performed, the correlation with visual evaluation is high.

IPC: H01S3/23
Filed: 1987-10-09
Abstract: PURPOSE:To simultaneously oscillate in different oscillation lines by independently providing laser chambers at respective optical oscillators, and independently controlling the laser gas mixtures of high pressure laser gain regions. CONSTITUTION:When low pressure laser gains are respectively sufficiently obtained by first and second low pressure discharge tubes 6, 9, a trigger is fed to a switching element 5, and discharge exciters 4, 28 are simultaneously operated.

Title: Roof snowmelt method
Inventor: KOBAYASHI EITA
IPC: F24D3/00
Filed: 1988-10-11
Abstract: PURPOSE:To lessen snowmelt ground water and energy to automatic the start and the stop of snowmelt by operating a device when the weight or the depth of a snow cover is equal to or more than the set point and stopping the device when it is less than the set point. CONSTITUTION:When a load applied on a snow cover meter 8 by the snow of a roof reaches the set point of a setter 9, a snowmelt controller 10 operates a boiler 2 and a fan 5. High temperature air heated by a heat exchanger 3 is sent to a radiating pipe 24 through a communicating pipe 23, released in a hot air room 29 from its radiating holes and snow is heated through the roof 18. The radiated air is returned to the heat exchanger 3 through a duct 30. When snowmelt proceeds and the load applied on the snow cover meter 8 is lightweighter than the set point, the device 1 stops. At this time, ventilating openings 31, 32 at the edge of the roof and under the eaves are opened to exhaust moisture stayed in the hot air room 29. Because not all snow is melted, energy consumption can be lessened without the need of the operation of start and stop.

Title: Semiconductor switch circuit
Inventor: ABE YOSHITAKA
IPC: H03K17/73
Filed: 1986-10-29
Abstract: PURPOSE:To cause no leakage of a current in a semiconductor switch circuit employing a PNPN switch element even if a voltage is impressed reversely by connecting at least one gate and substrate of a transistor at high resistance. CONSTITUTION:Where the potential VA of an anode A is higher than the potential VK of a cathode K and where a signal impressed on a control terminal 4 operates control current sources 2 and 3, the control current source 2 sucks a current through a route of the anode A an anode gate GAa resistance RP a gate GP the control current source 2 as long as the potential VA of the anode A is a one that the control current source 2 can operate. Thus the resistance RP causes a drop in a voltage, and MP operates with the emitter of QP as a source and its collector as a drain. A base current is allowed to flow through a route of the anode A in the PNPN switch 1 MP the base of QN the cathode K. After the base current flows in QN, the switch 1 is conducted. The same holds of the control current source 3. As the switch 1 can be driven by an electric field, resistances RN and RP are made at high level to reduce the drive currents of the current sources 2 and 3. Hence the current that leaks to a load line side from a control system can be reduced.
