Title: Semiconductor integrated circuit for light reception
Inventor: NARA MASAAKI
IPC: H01L31/10
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To improve the use efficiency of a light reception element, by making the light reception element in a cross form by means of excepting an area which is not irradiated with light in the light reception element. SOLUTION: A light reception element part 1 is formed in a cross form, and pads 3 are arranged in the light reception element part 1 of the cross form. The size of the cross form of the light reception element part 1 is made so that the use rate of the light reception element part becomes high against an area which is irradiated with light and all light irradiated through an opening part can be received. Thus, a light reception element area which is not irradiated with light is reduced, an area which is irradiated with light increases against the whole light reception element area and the use rate of the light reception element can be improved. Then, a pad (d) is adjacently arranged to the light reception element part 1 from a pad (a) for a signal processing part 2.  Thus, arrangement efficiency is improved and the size of a semiconductor integrated circuit can be reduced since the area which does not totally function as the light reception element at all before can be used.

Title: Cassette loading device
Inventor: MIHARA MASATO
IPC: G11B15/675
Filed: 1990-03-30
Abstract: PURPOSE:To unlock a door lock by a door lock member without providing any special unlocking means by unlocking the door lock by an operation piece which engages the gear of a driving force transmitting means which moves a holder. CONSTITUTION:A door lock releasing mechanism 240 controls a lock member 241 into a locked state when a cassette is not inserted. When the inserted cassette is moved to a specific loading position, the door lock releasing mechanism 240 operates the operation piece associatively with the rotation of the gear of the driving force-transmitting mechanism 400 to turn and control the lock member 241 from the locked state to the unlocked state, wherein the member is held. Consequently, the door lock is released by the door lock member 241 by the simple constitution without using any extra lock-releasing means such as a solenoid, so that the cassette can be ejected.

Title: Overload prevention circuit in x-ray device
Inventor: KANEKO KAZUO
IPC: H05G1/54
Filed: 1982-05-20
Abstract: PURPOSE:To accurately prevent the overload of an x-ray tube, such as the fault location of a switching circuit and excessive current of tube current by detection the input current of a high voltage transformer and cutting off a power supply circuit system using the detection current as the tube current conversion signal. CONSTITUTION:A signal (a) that is proportional to the current of a camera tube is obtained by detecting the input current of a high voltage transformer 11 and current/ voltage-converting it. A comparator compares the said detection signal (a) with the tube current reference voltage (f) from a tube current selection circuit 37 consisting of variable resistors 27 to 31 and changeover switches 32 to 36. When the detection signal (a) is larger than the reference voltage (f), a signal is output. A relay 38 is excited by the output signal and opens and controls a contact 38a inserted in the power supply circuit of an electromagnetic relay 21. Accordingly, a relay contact 21a provided at the front stage of a switching circuit 10 is opened and the input power supply of the high voltage transformer 11 is cut off. As a result, an x-ray tube can be prevented from being overloaded by detecting the input current of the high voltage transformer and the fault location of the switching circuit and the overload and excessive current for the x-ray tube.

Title: Capacitor protector
Inventor: OKADA YASUHIDE
IPC: H02H7/16
Filed: 1988-04-07
Abstract: PURPOSE:To prevent insulation breakdown, by removing a capacitor from a system when an electrostatic capacity obtained based on the voltage applied onto a self-recovery capacitor and the current flowing at that time and converted to a capacity corresponding to a standard temperature is lower than a predetermined level. CONSTITUTION:A self-recovery capacitor 1 is connected in parallel with a power source system L through a switch 3, a CT4 and a power factor improvement/surge current prevention reactor 2. Capacitance of the capacitor 1 is calculated 10 based on the voltage V of an output voltmeter 8 for a PT5 connected in parallel with the capacitor 1 and the current A of an ammeter 7 connected with the CT4. Temperature of that time is obtained through a thermometer 6 arranged closely to the capacitor 1, and the calculated capacitance is corrected to a value corresponding to a standard temperature through a reference temperature correcting section 11. The corrected capacitance is fed to a comparison output section 12, and when the capacitance is dropped below a predetermined level the switch 3 is opened to disconnect the capacitor 1 from the system. By such arrangement, insulation breakdown can be prevented.

Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetically encodable card by preparing a dispersion solution having ferromagnetic particles dispersed into an organic fluid medium, and closely mixing the dispersion solution with thermoplastic resin plasticized with the organic fluid medium to prepare a composite material. SOLUTION: Ferromagnetic particles such as γ-Fe2 O3 are dispersed into an organic fluid medium such as phosphoric ester to prepare a dispersion solution, and then the dispersion solution is mixed with thermoplastic resin such as polystyrene to prepare a composite material. During preparation of this composite material, a dispersing agent such as a product of phosphoric ester is included therein, but another of various types of dispersing agents may be used. In order to obtain a white color reflecting surface suitable for accommodation of image, etc., for example, particles of α-alumina are added to pigment containing metal oxide or oxide mixture or metallic carbonate, e.g. zinc oxide for providing an anti-friction characteristic to thereby form a composite material. The composite material is formed into a magnetically encodable card.  Since the magnetic particles are entirely uniformly dispersed, a magnetic signal in the card will not reduced even after the card is used many times.
