Abstract: PURPOSE:To minimize connection loss and to facilitate alignment at the time of connection by changing the height and width of a core where light propagates, to a taper shape in a light propagation direction at the input and output ends of the optical waveguide and near these ends. CONSTITUTION:A photoresist film 104 consisting of an org. material which is a photosensitive agent is applied on a core layer 102 on which grooves 103 are formed. The photoresist film 104 is applied at a large film thickness in the parts of the right and left grooves 103 in such a manner that the film thickness of the photoresist is tapered 112 at this time. The thickness of the photoresist film 104 is tapered, for example, about 3mum near the center of the substrate 101 and about 5mum near the grooves 103. The entire part is etched 6mum by a dry etching method using gaseous fluorine. The core layer 102 at the incident end and near the end is then worked into a taper shape. Further, the core layer is dry-etched by the gaseous fluorine, thereby, the waveguide having the core layer 109 expanded in the core layer 102 to the tapered shape on both height and width directions is formed.

Filed: 1988-08-02
Abstract: PURPOSE:To reduce the radiation dose rate nearby control rod drive hydraulic pressure devices(HCU) and to diassemble and inspect the HCUs in an area where a radiation atmosphere is low by arranging scrum discharge headers among HCU groups at intervals of four arrays.

Title: Master alloy for composition regulation, for use in recasting of zinc alloy metal mold
Inventor: KUBOTA KOHEI
IPC: B22C9/00
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To easily and simply repeat recasting of a metal mold by specifying Al content in a master alloy for composition regulation. SOLUTION: In this master alloy, it is preferable to limit Al content to 20-50% by weight. When used zinc alloy metal mold is recast, usually slag is formed by 3-5wt.%. In this case, when a master alloy of <20% Al content is used, the amount of an alloy to be added becomes inevitably larger than the amount of the slag formed and costs are increased. Further, when Al content exceeds 50%, the melting point of the master alloy becomes >=560 deg.C. Accordingly, at a molten alloy temp. of 430-450 deg.C used at the ordinary operation, the master alloy of >50% Al content is of no practical use because the length of time from the addition of the master alloy to the molten alloy to melting is extended. It is undesirable to raise the molten alloy temp. to >450 deg.C for the purpose of shortening the melting time, because a melting pot is attacked.

Title: Revolution speed change detecting device
Inventor: ICHINOSEKI JUICHI
IPC: G09B9/54
Filed: 1989-07-26
Abstract: PURPOSE:To detect the change of the speed of revolution and to confirm the speed of revolution of before the change and after the change by storing revolution speed data sent from a after-change revolution speed data storage means and outputting it as new before-change revolution speed data. CONSTITUTION:A revolution speed change detecting means 10 outputs a revolution speed changing signal, and when input revolution speed data gets out of a prescribed fluctuation range, reference revolution speed data is set again to the input revolution speed data of its time point. Also, when the revolution speed change is detected, an after-change revolution speed data storage means 11 sends the previous revolution speed data being in a stable state, stored until that time to the next stage, stores the present new input revolution speed data which becomes a stable state and outputs it as after-change revolution speed data. Subsequently, when the revolution speed change is detected, a before- change revolution speed data storage means 12 stores the revolution speed data sent from the after-change revolution speed data storage means 11 and outputs it as new before-change revolution speed data. In such a way, the change of the speed of revolution is detected, and the speed of revolution of before the change and after the change is obtained.

Title: Valve device for gas appliance
Inventor: INAGAKI HIDEO
IPC: F23N1/00
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To prevent the half opened state of a valve caused by the exhaustion of a battery so as to improve safety by making the difference between the valve opening driving force of an electric valve opening means and the valve opening force of energizing a valve element in a valve opening direction, smallest in a valve opening start position of a valve element. SOLUTION: A position of valve opening force first becoming lower than valve opening force by a spring 21 or the like in the case of the valve opening force of a push solenoid 30 being lowered by the exhaustion of a dry battery is made a valve opening start position of a valve element 20, that is, the difference between the valve opening driving force of the push solenoid 30 and the valve opening force by the spring 21 and gas pressure is made minimum in the valve opening start position. Between the valve opening start position and a fully opened position, the increase degree of the valve opening force therefore becomes larger than the increase degree of the valve opening force, and the grade of valve opening force and that of valve opening force are not reversed during valve opening.  A valve is not therefore opened in completely by the exhaustion of the dry battery so as to improve the safety of a gas appliance.

Abstract: PURPOSE:To obtain a high speed bi-polar transistor by forming an emitter layer, a base layer, and an isolation oxide film by self-alignment. CONSTITUTION:An N<-> epitaxial layer 12 are superposed on an N<+> buried layer 11 of a P type Si substrate 10 and then surrounded by an SiO2 13. A P<-> type single crystal 14, a P<-> type poly Si 16, an N<+> single crystal 15, and an N<+> poly Si 17 are laminated by molecular beam epitaxial method, and an Si3N4 mask 18 is applied. The N<+> layer 17 is selectively removed with a solution whose rate of etching of the N<+> layer to the P<-> layer is 5 or more, and thus the side wall of the N<+> emitter layer 15 is exposed. Next, the P<-> layer 16 is changed into a P<+> layer 16' by ion implantation, and is then covered with a thermal oxide film 19'. At this time, a P<+> layer 20 is generated in the base 14. An SiO2 on the film 16' is removed by anisotropic etching, thus making the film 19 remain selectively, Mo, etc. are vapor-deposited and annealed, resulting in providing an MoSi 21. Then, it is covered with an SiO2 film 22, and electrode 23 and 24 are laid by providing apertures. This constitution makes the distance between the base and the emitter shortened, then enables to reduce the external base resistance, therefore to obtain the excellent high speed bi-polar element.

Title: Current driving circuit and magnetic disk device using said circuit
Inventor: SATO NAOKI
IPC: G11B5/09
Filed: 1989-07-28
Abstract: PURPOSE:To prevent the destruction of a transistor against the instantaneous rise of a collector potential by providing a means detecting the collector potential of the transistor and a floating constant voltage generation means and a means controlling a base potential. CONSTITUTION:The collector potential VQC of the transistor Q driving a current suddenly rises when a pulse current IP is disconnected and it intends to become more than the CE withstand voltage of the transistor Q. At that time, the collector potential VQC is detected in the collector potential detection means. When the rise of VQC exceeds the voltage of the constant voltage generation means, VQB is raised in the base potential control means by adjusting it to the rise. Consequently, the potential VCE between the collector and the emitter of the transistor Q is held less than a prescribed value, and is set lest is exceeds CE withstand voltage. Thus, the collector terminal voltage of the transistor Q which supplies the pulse current IP to a recording head L suddenly rises by a flyback voltage generated when the pulse current IP is turned off, and is prevented from exceeding CE withstand voltage.
