Title: Bush insertion jig
Inventor: KANBARA YOSHITAKA
IPC: G01B5/00
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To provide a bush insertion jig which can markedly enhance positioning accuracy of a bush in a through hole. SOLUTION: By using a platelike and irregular-shaped seat body 21, in which side parts 26a, 26b specifying a central position on an outer peripheral face are formed and a jig main body 20a having a fitting shaft 22 protruding from this seat body 21, a cylindrical bush 9a is held at a fixed attitude, and the bush 9a is inserted into a through hole 10 by aligning the side parts 26a, 26b of the jig main body 20a with each part of a marking-off line 11 marked at an opening fringe of the through hole 10. Consequently, it is possible to change the positioning work liable to cause an error into the work that merely aligns a position with the marking-off line 11 of the through hole 10 so as to perform position alignment of the bush 9a with high accuracy.

Title: Proximity fuse
Inventor: HIDAKA YOSHINORI
IPC: F42C13/04
Filed: 1989-11-13
Abstract: PURPOSE:To obtain a fuse having a function for eliminating an erroneous operation, saturation of a receiver system due to reflection wave from the ground or sea surface by using a variable attenuator inversely proportional to the square of a distance in attenuation amount, and maintaining a reception signal input to a mixer due to a reflected wave constant irrespective of a distance to the ground or sea surface. CONSTITUTION:The output of an integrator 21 is so controlled as to include information of a distance from a missile to the ground or sea surface by a tracing loop and hence to be inversely proportional to the square of a distance from the missile to the ground or sea surface in the attenuation amount of a variable attenuator 17 by a function generator 22. Thus, a reception input due to a reflected wave from the ground or sea surface to a mixer 6 is attenuated inversely proportionally to the square of the distance from the missile to the ground or sea surface by the operation of the attenuator 17. Since the intensity of the wave from the ground or sea surface is inversely proportional to the square of the distance, the reception power due to the wafer to the mixer 6 is not varied according to the distance from the missile to the ground or sea surface by the use of the attenuator 17.

Title: Optical transmission system
Inventor: TAKEHIRA MITSUSHI
IPC: H04B10/548
Filed: 1986-12-09
Abstract: PURPOSE:To suppress the deterioration of the S/N of a supervisory control signal sent even at multi-relay state by utilizing it that the fluctuation of a light passing through an optical transmission line is caused in response to the change in the stimulated light wavelength. CONSTITUTION:When a signal whose stimulated light wavelength is modulated by a repeater 7 passes through an optical fiber 6, a delay difference of a wavelength due to the dispersion by the optical fiber is caused. In receiving and amplifying a transmission signal by an APD module 5 of a repeater 8, the phase of the transmission signal is fluctuated in response to the modulation frequency of the stimulated wavelength. The phase change is detected and recovered by a phase detection recovery circuit 2 of the repeater 8, the stimulated wavelength of a laser module 3 is modulated again and the information is sent to the next repeater. Thus, the deterioration in the S/N of a supervisory control signal due to phase modulation is prevented even at multi-relay processing.

Title: Transistor
Inventor: TOKURA YASUHIRO
IPC: H01L29/201
Filed: 1988-11-21
Abstract: PURPOSE:To obtain functions of a phototransistor to be controlled by an external magnetic field with high controllability and high speed response by externally applying a magnetic field to arrive the part of electrons passing a semiconductor crystalline layer at a third electrode layer. CONSTITUTION:If a magnetic field 17 of a direction perpendicular to the arraying direction of step faces A1-A6 of a semiconductor crystalline substrate 1 is applied, electrons are bent in response to the intensity of the magnetic field. Thus, part of the electrons is arrived at a third electrode layer 16 through a semiconductor crystalline layer 7. The other part of the electrons tend to be introduced into the second semiconductor layer 5 of a first superlattice 3, but since the layer 5 operates as a barrier layer, the electrons are reflected on the layer 5, and the part is arrived at a third electrode layer 6. Thus, the functions of a phototransistor to be controlled by the external magnetic field are obtained by high controllability and high speed response.

Title: Semiconductor memory
Inventor: NOGAMI KAZUTAKA
IPC: G11C11/407
Filed: 1988-11-21
Abstract: PURPOSE:To shorten cycle time in a semiconductor memory by outputting a row decoded signal by a row address, synchronizing the row decoded signal with a synchronizing signal, and latching the row decoded signal when the row address is inputted to a memory cell array, and a word line is driven according to the row address. CONSTITUTION:The row address is applied to a row decoder 11 and sent to a latch 12 as the row decoded signal. The latch 12 fetches the row decoded signal synchronously with a synchronizing clock signal phi and drives a word line 13. On the other hand, a column address is applied to a column decoder 16 and sent to a latch 17 as a column decoded signal. The latch 17 fetches the column decoded signal synchronously with the synchronizing clock signal phiand outputs the signal through an input/output circuit 19 to a bit line 18 as a column selecting signal. Thus, the row and column decoded signals are applied to a memory cell array 14, and the cell data of an address corresponding to the applied signals are outputted through the bit line 18 and the input/output circuit 19 to a data line 20.

Abstract: PURPOSE: To make it possible to integrally roll a skin material into a resin when a molding operation is performed by first, removing the surplus end of the skin material by shearing at the open edge of a female half of a die and the outer edge of a male half during an ongoing die clamping, and rolling the edge part of the skin material into the molding part of a wooden end surface of the male half of the die along the molding part to supply the molten resin. CONSTITUTION: After thermally curing a skin material 20, the material 20 is vacuum- sucked into a female half 1a of a die by a vacuum hole 2, and the female half 1a is caused to descend and simultaneously a molten resin begins to be injected from the gate 3 of the male half 1b. In this case, the surplus end of the skin material 20 is cut off by the blade 5a of the female half 1a and the shearing blade 5b of the male half 1b. Next, the edge part of the skin material 20 is rolled inwardly along the inner surface of a curved groove-like wooden surface molding part 7 on the outer periphery of the male part 1b in a process up to a die clamping step. On the other hand, the molten resin to be supplied into a cavity part from the gate 3 reaches the wooden end surface molding part 7 on the outer periphery of the male half 1b.  Then, the resin finds its way into the interior of the skin material 20 and spreads pressing the skin material 20 against the inner peripheral surface of the cavity.

Title: Air-conditioner auxiliary device
Inventor: KADOKAWA MASARU
IPC: B60H1/22
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To enhance airtightness between each door opening and closing an opening in an adsorbent chamber and the opening. SOLUTION: When auxiliary heating is not perfomed, doors 3a, 3b are closed, and air inside an adsorbent chamber 2 is sucked by means of a vacuum pump 6. The pressure within the adsorbent chamber 2 is thus made lower than atmospheric pressure, and forces oriented toward both inlets 2a, 2b are made to work on the doors 3a, 3b by the differential pressure between the inside and outside of the adsorbent chamber 2. The doors 3a, 3b are therefore pressed by the inlets 2a, 2b, so airtightenss between them can be enhanced.
