Title: Connecting terminal device
Inventor: MORI TATSUYOSHI
IPC: H01R13/44
Filed: 1992-08-18
Abstract: PURPOSE:To reduce the number of part items. and improve the assembling property, and reduce cost by forming a groove hole in the installation surface, and providing a cantilever guard support piece and a connecting terminal piece, which can be displaced elastically. CONSTITUTION:Under the condition that a battery is not installed to the installation surface 2, a guard part 7x of a terminal housing opening part 6x projects from the installation surface 2, and a contact terminal part 8x is covered with the guard part 7x to prevent the short of the contact part 8x. On the other hand, under the condition that a battery Eb is installed to the installation surface 2, the guard part 7x is pushed by the battery Eb, and a guard support piece 3x is displaced elastically. At this stage, since the battery Eb abuts on the installation surface 2, the projecting side end of the guard part 7x is pushed to a position of the installation surface 2. Consequently, a connecting terminal piece 4x made of plate spring material is displaced elastically, and the contact terminal part 8x provided in the tip side thereof contacts with a terminal part, to which a contact terminal part contacts, provided in the battery Eb side, and they are connected. Contact failure is thereby prevented to secure the stabilized electrifying condition.

Filed: 1983-12-21
Abstract: PURPOSE:To improve the efficiency of distance measurement by superposing two upper and lower work films one over another and simultaneously taking measurements of distance. CONSTITUTION:Two work films 1 and 1' are shifted in the directions of an X and an Y axis respectively to superpose patterns one over another, and a photosensitive layer 10 is positioned on the reverse surface side of each base 9 to project light thereupon by a distance measuring machine. At this time, when the pattern of one work film is put in focus optically, the other is out of focus and they are recognized easily and distinctively. The distance of the guide hole 4' of the work film 1' is measured on the basis of the position of the guide hole 4 of the work film 1 to input the distance to a computer, and the distances of sampling patterns 5 and 5', 6 and 6', 7 and 7', and 8 and 8' are measured similarly and inputted to the computers, thereby making a return to the guide hole 4 as the origin. In this example, the distance measurement for inspecting the position shift between patterns of two work film is carried out in a short time, e.g. 9min in total.

Title: Emergency cooling system for atomic reactor
Inventor: ARAKI HIDEFUMI
IPC: G21C15/18
Filed: 1992-09-10
Abstract: PURPOSE:To lessen an area where cooling water becomes hot in temperature by setting a water filling pipe in such a way that the pipe has a section which allows cooling water to flow upward within the water filling pipe of a cooling system so as to allow it to be poured. CONSTITUTION:In normal operations, since coolant flowing within a pressure container 2 is high in temperature, cooling water in a piping line 30 is naturally circulated by convection within the line because of convection heat transfer from the communication section of the container 2. Cooling water located in a place lower in level than the communication section is formed into cooling blocks, so that each temperature lamination is thereby formed within the pipe line 30. By this constitution, cooling water within a piping line 32 is increased in temperature mainly because of heat transfer, but the increase is small as compared with that of natural convection. Therefore, the loss in the heating value of the container 2 is reduced. Even if coolant is lost from the container 2 because of failures, hot and high pressure vapor within the container 2 is emitted to a pressure restraining pool 5 and a dry well 3 with both an escape valve and pressure reducing valve released, a check valve 29 is opened when pressure is lowered down to pressure which enables coolant to be poured in, and cooling water within a gravity fall water container 26 is poured in the container 2, so that a furnace core 1 is thereby kept submerged. In this case, since temperature within the piping line is low, water will never be boiled within the piping line, water can thereby be poured in a liquid phase.

Title: Photocoupler circuit
Inventor: OTSUKA YOSHIHIRO
IPC: H03H11/02
Filed: 1987-09-25
Abstract: PURPOSE:To obtain an output which does not completely depend on the current transfer ratio of a photocoupler by providing a photoelectric current amplifying circuit to drive the light emitting element of the photocoupler with a current to superimpose an alternating current, logarithmicly convert the photoelectric current output from a light receiving element and further, reversely logarithmicly convert only an alternating current component. CONSTITUTION:By an LED driving circuit B1, a current IF(AC) due to an alternating current signal and a direct current bias current IF(DC) flow at the LED and a light signal L in proportion to the current to superimpose two currents is transferred to a photodetector PD. In a logarithmic amplifier A1, a transistor Q4 is operated at a base ground and a light current IP is converted to a voltage output V01 by the logarithmic amplifier A1. A reverse logarithmic amplifier A2 is combined to an integrating circuit I1 and operated as an alternating current amplifier. Consequently, the output of a light-receiving element is in proportion to IF(AC)/IF(DC) only, does not completely depend on the current transfer ratio to fluctuate due to the dispersion and the change with the passage of time and temperature change between the photocoupler and the product, and therefore, the output signal in proportion to the input signal stably can be obtained.

Abstract: PURPOSE:To decrease the noises to be induced in a magnetic head provided to the rear surface of the surface to be recorded with information by providing a superconducting layer on a substrate consisting of a glass or nonconductor high-polymer molding. CONSTITUTION:The superconducting layer 2 consisting of a superconducting material and having, for example, several mum thickness and a magnetic recording layer 3 are provided on the substrate 11 consisting of the glass or nonconductor high-polymer molding. The superconducting materials are the oxides of, for example, La, Ba, Cu, the oxides of La, Lr, Cu and the oxides of Y, Ba, Cu, for example, ceramics superconductors and metal superconductors such as (Y, Ba)3Cu2O7. The magnetic fields generated by the magnetic head at the time of recording information arrive at the magnetic recording layer 3 and magnetize the magnetic recording layer 3 but since there is the superconducting layer 2 between the magnetic recording layer 3 and the substrate 11, the magnetic fields generated by the magnetic head are shielded by the superconducting layer 2. The substrate is thus prevented from being affected by the magnetic fields generated by the magnetic head. The influence of the magnetic fields from the magnetic head which makes recording to the magnetic head placed on the rear surface of the surface to be recorded with the information and the induction of the noises therein are prevented in this way.

Abstract: PURPOSE:To obtain a semiconductor memory device, which has a large product yield and can operate with small energy consumption, by providing a switching means to apply an operating current to a redundant circuit to be used, and to interrupt the operating current at the redundant circuit not to be used. CONSTITUTION:When a reference voltage VCS1 of an address comparing circuit 6 is set at the negative voltage, the transistor (TR) of a constant current source is interrupted.

Consequently, even when the number of defective word lines is smaller than the number of the redundant word lines WL (R) and the unused redundant circuit exists, the product yield can be made larger and the energy consumption is made smaller by making the reference voltage VCS1 negative.
