Patent JP-S62264674-A (JP)
Title: Substrate for forming solar cell or circuit
Inventor: ONO JUN
IPC: H01L21/52
Filed: 1986-05-13
Abstract: PURPOSE:To obtain a flexible substrate having improved strength and flatness suitable for forming circuits, by coating one face of an austenite stainless steel plate having a thickness of 0.3mm or below with enamel. CONSTITUTION:At least one face of an austenite stainless steel plate having a thickness of 0.3mm or below is coated with enamel to provide a substrate for solar cells or the like. Since the austenite stainless steel starts recrystallization at a temperature of 900-950 deg.C, it is not softened during a baking process carried out at a temperature of about 820 deg.C for treating the enamel. Further, the 0.3 mm thick material is cold rolled such that it is finally worked at least by 50% or more, in order to prevent deformation or strain caused by sandblasting the material for improving its adhesion properties with the enamel and to ensure sufficient strength. The cold rolled material may be annealed for one to ten minutes at a temperature of 400-800 deg.C for the purpose of eliminating strain, whereby the flatness of the stainless steel plate coated with enamel is further improved.

Title: Rotational driving device for optical disk
Inventor: ASHIBE NOBORU
IPC: H02K5/22
Filed: 1994-04-21
Abstract: PURPOSE:To prevent generation of torsional resonance by coupling a disk table and one end of a rotor case and integrally and rotationally driving both. CONSTITUTION:The disk table 9 to be mounted with the disk is integrally mounted above a bearing 6 on the upper side of a shaft 7. One end of the cylindrical rotor case 5 is coupled to the outer peripheral edge on the rear surface side of the disk table 9. A disk cable 9 is mounted directly to one end of the rotor case 5, by which the rotor case 5 and the disk table 9 are integrally rotated; in addition, the size between the rotor case 5 as the driving part of the shaft 7 and the disk table 9 as the output part attains an extremely small value and, therefore, the torsional resonance which is heretofore the cause for a disk access defect is prevented. The area where a pickup device enters is sufficiently assured by notching the bracket part 1a of the holder 1 to a semicircular shape.

Title: Control device for engine
Inventor: AKIYAMA SUSUMU
IPC: F02D41/24
Filed: 1984-05-28
Abstract: PURPOSE:To secure engine control information on a fuel injection quantity and so on in a simple operation state, by expressing a suction air flow rate with pulse duration width of a pulse-form detection signal, while using a digital- formed detecting output signal out of an air flow detector. CONSTITUTION:When a heating current to a temperature sensitive element 17 is in a constant state, temperature of the temperature sensitive element 17 rises in a state corresponding to air flow inside a suction pipe 13. Therefore, a time interval ranging from the setting time of a flip-flop (F.F)34 to the time being reset comes into a state of being conformable to the air flow. That is to say, the time interval the F.F34 being set is one corresponding to the suction air flow whereby time width of a pulse-form signal to be produced in response to the set/ reset of the F.F34 comes into a state of being conformable to the air flow. An output signal out of the F.F34 comes to an air flow detection signal so that it is expressed with the time width and period. This signal is fed to an engine control unit as the output signal of an air flow measuring device and used for operation control of a fuel injection quantity.

IPC: G09G3/06
Filed: 1988-04-30
Abstract: PURPOSE:To unify brightness with simple circuit constitution by driving anode segments and grids of a 2nd fluorescent display part in synchronism with the time-division driving of at least one grid of a 1st fluorescent display part. CONSTITUTION:A synchronous control part 4 drives the anode segments and grids of the 2nd fluorescent display part 1c in synchronism with the time-division driving of one grid of the 1st fluorescent display part 1b. At this time, the synchronous control circuit 4 generates a synchronous driving signal by using the output signal of a grid control circuit 3 to the fluorescent display part 1b. Consequently, a circuit for generating the synchronizing signal need not be provided and the fluorescent display parts 1b and 1c are both driven dynamically, so a circuit for unifying the brightness need not be provided either, so the circuit is simplified. Further, when the fluorescent display part 1c is driven, the frequency of the synchronization with the time-division driving of the grids of the fluorescent display part 1b is varied to easily adjust and unify the brightness of the fluorescent display part 1c.

Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To control temperature of thermoelements within an upper limit despite of high exhaust gas temperature and ensure the power generation efficiency under low exhaust gas temperature for an exhaust heat recovery power generation system employing the thermoelements. SOLUTION: Thermoelements 4 and cooling jackets 5 are arranged on both sides of an exhaust pipe 3 and fastened by bolts 7 which penetrate the exhaust pipe 3 and the cooling jackets 5, so as to sandwich in these from outside of the cooling jackets 5. For making the bolts 7, a material having a larger thermal expansion coefficient than those of the exhaust pipe 3 and the thermoelements 4 is selected. Accordingly, when the exhaust temperature has become high, the contact pressure between the thermoelements 4 and the exhaust pipe 3 decreases, and the thermal heat resistance increases. As a result, a temperature rise which exceeds an upper limit of the thermoelements 4 can be prevented.
