Title: Semiconductor photodetecting device
Inventor: TAKAHASHI HIDEO
IPC: H01L31/10
Filed: 1989-04-25
Abstract: PURPOSE:To apparently reduce a necessary bias voltage to about one-half, and form a semiconductor photodetecting device easy to be used by constituting a driving circuit for ADP bias in a monolithic type, and mounting it on the same package as an ADP chip. CONSTITUTION:When outputs from a buffer Ib1 and a buffer Ib2 are input to a voltage multiplier, the input signal viewed from the voltage multiplier 2 fluctuates in a pulse between voltages VCC and VEE. When +VCC inputs, a transistor TR Q1 turns ON, a TR Q2 turns OFF, a TR Q3 turns OFF, and a TR Q4 turns ON. The charging current flows in the order of Q1 C2 D2 C 3 Q4. At this time, the charging voltage of a capacitor C3 becomes a value wherein the charged voltage of the capacitor C2 is added to the emitter potential of the TR Q1, because the capacitor C2 has been already charged. As a result, a voltage of 2X¦CC-VEE¦ is applied to the capacitor C3. Thereby a bias voltage necessary to a conventional avalanche photo diode ADP can be reduced apparently to about one-half.

Title: Method of repairing and executing recreation equipment
Inventor: REO SHIYUURAA
IPC: H04M11/00
Filed: 1992-04-24
Abstract: PURPOSE: To reduce the cost required for repair by indicating a fault in a component group or a component section by a signal from a terminal and sending fault information to a customer service station or a device via a telephone network. CONSTITUTION: A television receiver 1 has lots of measuring points and a voltage at each point is used to indicate a defect of a component section. A digital signal including a fault, a manufacturer, and a device model and other service data is sent to a telephone set 6 of a customer service station via a telephone line 5. Thus, the manager 9 of the customer service station decides whether or not repair is enough to cover the defect or which renewal part or component is required for the repair. A customer service repair personnel 10 carries the spare parts and is dispatched to the customer. Thus, the repair personnel carries the correct renewal part and an undesired cost relating to a repair visit is avoided.

Title: Digital-analog converter
Inventor: OOHATA MICHINOBU
IPC: H03M1/66
Filed: 1978-08-31
Abstract: PURPOSE: To decrease the width of the supply power source of the D/A converter by connecting the 2-split D/A converters in parallel via the current Miller circuit.  
     CONSTITUTION: The 1st current division circuit 31, which carries out the segment division, consists of current source 33-n to divide current IFS of constant current source 32 into IFS/2 n  (n=1∼6), current source 33-7 of IFS/64 and change-over switch S-n provided in accordance with each source 33-n. If the current division ratio of circuit 31 is set to (a), current IS 1  of line 34 becomes equal to aIFS. For current Miller circuit 20, current IS which is equal to current IS 1  flown to terminal 27 flows to terminal 28. And if division ratio of 2nd current division circuit 35 featuring the same structure as circuit 31 is set to (b), the output current of 2nd D/A converter is obtained as abIFS since the current of line 36 is aIFS. Thus the same function is obtained as that in which two D/A conversion circuit parts are piled on each other, thus decreasing the power source width down to 1/2.

Title: Corrosion-proof electric wire
Inventor: NAGAOKA SHIROO
IPC: H01B7/28
Filed: 1987-04-30
Abstract: PURPOSE:To maintain the high corrosion-proof characteristic for a long time by winding a composite tape on a stranded conductor, with its plastic porous layer coated and impregnated with a rust preventive faced to the outside. CONSTITUTION:A plastic porous tape 1 coated and impregnated with a rust preventive layer 2 on one face and a plastic tape 3 bored with many small holes 4 on both faces are laminated to form a composite tape. The composite tape with such constitution is wound on a stranded conductor with the tape 1 face faced to the outside, and a plastic insulator is coated on it to form a corrosion-proof electric wire. The rust preventive such as benztriazole BTA impregnated into the tape 1 is not brought into direct contact with a copper conductor, and the greening of the conductor surface due to the abrupt reaction between Cu<2+> and BTA does not occur. Since the rust preventive passes through the small holes 4 and reaches the conductor surface while being volatilized little by little, the high corrosion-proof characteristic is maintained for a long time.

Title: Piston ring for internal-combustion engine
Inventor: OZAWA HITOSHI
IPC: F16J9/26
Filed: 1979-08-25
Abstract: PURPOSE:To prevent the reduction in the capability of sealing the gas pressure in a combustion chamber by a method wherein Ni-Resist having a coeficient of thermal expansion approximately equal to that of aluminum alloy is used as the material for the piston rings for an internal-combustion engines. CONSTITUTION:Ni-Resist having a coefficient of thermal expansion of 18X10<-6>, which is as high as that (about 18.6X10<-6>) of aluminum alloy, is used as the material for the piston rings for the cylinder liner of an internal-combustion engine made of aluminum alloy. Accordingly, the butt joint 7 of the piston ring is larger in operation than in cooled state, and it is not increased largely even when the cylinder liner expands. In addition, since the piston ring generally gats temperature higher than the cylinder liner, the clearance between the liner and the ring becomes smaller. Accordingly, the reduction in the capability of sealing the gas pressure is prevented.
