Title: Ceramic electronic parts and manufacture thereof
Inventor: KAWAHATA KIYUUICHI
IPC: H01G4/232
Filed: 1990-05-17
Abstract: PURPOSE:To effectively prevent the generation of cracks and the like, by absorbing the stress caused by the deflection of a circuit board and the like, in the bonding interface between an Ni-plated layer and an outside plated layer. CONSTITUTION:The stress caused by the deflection of a printed circuit board 6 is applied to solder 7a, 7b and a laminated capacitor 11. Ni-plated layers 14a, 14b and layers 15a, 15b are not rigidly bonded in the capacitor 11, so that the layer 14b and the layer 15b and separated and an air gap 17 is formed when large stress is applied. The same phenomenon is generated between the layer 14a and the layer 15a. As the result that the gap 17 is formed, the stress caused by the deflection of a substrate 6 is absorbed by a lamination plated film part, so that large stress is not applied to an electronic parts element body 12. Thereby the generation of cracks in the electronic parts element body 12 can effectively be prevented.

Title: Multi-cylinder 4-cycle engine
Inventor: ISAKA YOSHIHARU
IPC: F02B75/18
Filed: 1983-07-14
Abstract: PURPOSE:In a multi-cylinder engine whose ignition intervals are irregular, to increase an output of the engine as a whole by heightening the compression ratio of at least one cylinder having a suction valve which opens at high rotational speeds and accordingly enhancing the heat efficiency of this cylinder. CONSTITUTION:Since a suction valve 13 of a first cylinder opens and closes in the range of lower rotational speeds than those at which a suction valve 13 of a second cylinder is operated, the period of time for which the valve opens is so short that a suction amount is insufficient. The compression ratio is consequently reduced to cause a decrease in the heat efficiency. For this reason, a cylinder head 6 is shallowly scooped out so as to reduce the volume of a combustion chamber 7 and heighten the compression ratio. As a result, even if an amount of fresh air aspirated into the cylinder is insufficient compared with that aspirated into the other cylinder, the heat efficiency of this cylinder is heightened to cause an increase in an output of the engine as a whole.

Title: Measurement of distance
Inventor: ARAI TAKAFUMI
IPC: G01B11/00
Filed: 1987-05-26
Abstract: PURPOSE:To enable the highly accurate measurement of a distance, by a method wherein an object to be measured is introduced into a photosensor and the amount of passage of this object is subjected to addition or subtraction to measure a distance of passage thereof. CONSTITUTION:A long polyamide thread 1 of a diameter 0.3mm, for instance, is introduced into a reflection-type highly sensitive photosensor 2 and made to pass therethrough rapidly by 100m, the amount of passage of the thread 1 is detected by a counter 3, and thereby it is identified that the amount is 100m. Since the thread 1, which is an object to be measured, is introduced in between beams projected and reflected between a projector 4 and a reflector 5 in the photosensor 2, such a slippage error as occurs between a pulley and the object in a method of passage via the pulley is not produced, and thus a distance measurement with high accuracy can be realized.

Abstract: PURPOSE:To shorten the transmission distance of an optical fiber by controlling the operating point of the optical modulator while changing a direct current bias to be impressed to an electrode corresponding to the change of an output electric signal photodetected and converted by a photodetector. CONSTITUTION:When the operating point is deviated, a beam radiated from a joining point 22 of branched optical waveguides 2a and 2b is taken out as a monitor beam at the back of a substrate 1.
