Title: Disc cartridge clamp structure
Inventor: YAMAMOTO EIJI
IPC: G11B17/03
Filed: 1984-10-08
Abstract: PURPOSE:To attain accurately the center positioning by providing a clamp interposed and fixed tightly between the fringe of it and the fringe part of the turn table a disc. CONSTITUTION:When a disc 5 is inserted in the device and lowered by a loading structure initial it touches a leveler 1, there is a possibility that the disc may stay slanting because it is just touching the leveler 1. Next, when a clamp 3 comes down and touches and depresses the leveler 1 down, the disc 5 goes down by its own weight and stays on a turn table 2. While pressing down the leveler 1, the upper clamp 3 touches the center hole of the disc 5 with its taper part, and makes center positioning. And, fringe parts of the clamp 3 and the turn table 2 interposes the disc 5 between them and fix it.

IPC: G11C11/401
Filed: 1994-09-05
Abstract: PURPOSE: To avoid destruction of memory elements by forming a word line selecting and controlling circuit and making simultaneous writing into the same address impossible. CONSTITUTION: When the write enable signals,. WEI and WEJ, are at the H- level, the write enable(WE) registers, 13 and 21, outputted at the H-level is obtained. As the results, the AND circuit 90 works as a buffer for the output of the write pulse generator 14. And the outputs of the NOR circuit 81 and NAND circuit 91 come to be at the L- and H-levels respectively and the AND circuit 92 buffers the output of the write pulse generator 22. The write pulse generators, 14 and 22, maintain the row decoders, 16 and 24, in their inactive states since their respective write enable signals. WEI and WEJ, are at the H-level. Consequently, the writing of data Io to In , Jo to Jn , are made impossible without being limited to the I-port and the J-port.

A valve control circuit 10 controls the regulation valve 3 corresponding to said difference voltage. When the output voltage rises and the difference voltage becomes zero, since the output voltage becomes a value smaller by the pressure corresponding to the predetermined voltage E3 than the set voltage, the output pressure is allowed to coincide with the set pressure on and after by minute pressure control bellows 6 while the display of a display device 11 is being observed.

Title: Fixation of wind shield for timepiece
Inventor: UMEZAWA SEIJI
IPC: G04B39/02
Filed: 1987-08-27
Abstract: PURPOSE:To prevent protrusion of a both-sided adhesive tape from a fixation part of a wind shield and to diminish a width of the part, by trimming off an outer circle of the both-sided adhesive tape and by half-blanking an inner circle of the tape. CONSTITUTION:A both-sided adhesive tape 100 is set on a fixation part 210 of a wind shield of a watch case 200 with its condition of an inner circle 140 half blanked and a protecting paper 130 to be left on an upper surface of the tape 100. Using a cutting edge 510 having a shape corresponding to a shape of the trimmed off inner circle 120, a chisel 500 is pushed into the tape 100 from above the protection paper 130 and thereby the inner circle 140 is removed leaving the outer circle 150 at the fixation part 210. Thereafter, the protection paper 120 is taken off and the wind shield for a watch is downwardly stuck and fixed from above the tape 100. The outer circle 150 does not protrude into an inner side of the case and can diminish a width of the fixation part 150, because a force of the chisel 500 does not work on the fixation part 150 during this process.

Title: Semiconductor device
Inventor: KUKIMOTO YOSHIHIRO
IPC: H03K17/08
Filed: 1993-08-26
Abstract: PURPOSE:To quickly execute overcurrent limiting operation by constituting a circuit for feeding back a change in output voltage to the gate of an output transistor(TR) of an n-ch MOS TR and a constant voltage element. CONSTITUTION:If abnormality occurs in a load 5 connected to an output terminal 6 in an output ON state, e.g. when the terminal 6 is shortcircuited with a power supply VDD inn a low resistance state, the voltage of the terminal 6 is suddenly boosted and a current flowing into an output TR 4 is increased. However when the threshold voltage of the n-ch MOS TR 3 is dropped, the gate voltage of the TR 3 is dropped up to (the VF of a constant voltage element 2 + the ON voltage of the TR 3) to control the current flowing into the TR 4. A current value to be limited can be determined by changing the number of states of the constant voltage element 2, a diode in this case.

Title: Heat exchanger
Inventor: SAWADA TAKASHI
IPC: F28F1/12
Filed: 1986-09-09
Abstract: PURPOSE:To improve heat exchange performance and provide freedom in shape and raise reliability by making heat exchange between a heating medium which flows in a pipe passage and the air which flows through pores in a porous metal and, after building a pipe passage, forming the porous metal tight contacting with the pipe passage. CONSTITUTION:A porous metal 5 which has continuous pores covers the external face of a pipe passage 4 with tight contact between them. When this is used for room heating the heating medium flowing through the pipe passage 4 and the air which flows in the external face of the porous metal 5 exchange heat between them to transfer heat from the heat medium to the air. At this time because the rate of porosity of the porous metal 5 which works as fin is made small, the air flow is disturbed and the heat conduction is improved and the heat exchange performance becomes better. Further, there is not necessity to connect the pipe passage 4 with welding but only bending of a single pipe is required with the possibility of providing a desired shape of heat exchanger. It is, therefore, possible to make a circular heat exchanger and it is possible to provide a shape of heat exchanger that fits the circular flow such as that from a propeller fan.

Abstract: PURPOSE:To improve the reduction effect in the central part of a steel stock by starting rolling of the stock heated to a temp. higher than the Ac3 point, cooling the stock so that temps. at the surface and in the central part down to respectively specific temps., then reheating the stock up to a prescribed temp. range, and continuing the rolling. CONSTITUTION:A cast steel stock is heated to a temp. higher than the Ac3 point and rolling of the stock is started. At that time, the stock is cooled so that a surface temp. is at a temp. lower than the Ar1 point and a central part temp. keeps a temp. higher than Ar3 point. Then, the stock is reheated so that the surface temp. is at a temp. in the range higher than the Ac1 point + 20 deg.C and lower than the Ac3 point and the rolling is continued. Hence, the stock surface layer part transforms from ferrite to austenite during the temp. rising and the central part is an austenitic phase or is in a state where the part is transforming to ferrite. Therefore, the central part bears a strong draft and the drafting effect is improved because a large difference between deformation resistances of the surface layer and central parts is generated.
