Title: Magnetic bubble memory device controller
Inventor: CHIBA SHINSAKU
IPC: G11C29/56
Filed: 1983-04-22
Abstract: PURPOSE:To attain easily the analysis of defect at the generation of data error of a magnetic bubble memory device by reading an error data directly from a host computer so as to specify a minor loop having an error depending on the read. CONSTITUTION:When an operation mode switching input terminal 10 is in the normal operating mode (e.g., an ''H'' level), an error correcting circuit 8 conducts error correction to an error possible for correction. Further, as to an error impossible for correction, it is not required to move the data to the memory of the host computer 1. However, when the operating mode switching input terminal 10 represents the test operation mode (e.g., an ''L'' level), the error correcting circuit 8 detects only an error as to the error possible for correction and does not correct the data and moves the data to the memory of the host computer 1 while the error is generated. Thus, the data ia compared with the written data so as to specify the minor loop having an error.

Title: Semiconductor testing device
Inventor: YAMASHITA KAZUHIRO
IPC: G01R31/319
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To make preventible a prolonged testing time by testing in the state that a PLL circuit is phase-locked for the period from a pattern stop to the next pattern start when a plurality of patterns are continuously generated. SOLUTION: CLK 120 is continuously supplied to a clock pin 41 by RATE 210 until after lock end, a phase synchronization of a PLL circuit 45 is started and DATA 620 is output by a GATE 400 to test. After pattern stop, the GATE 400 is cut off and CLR 310 is not output and the RATE 210 does not terminate and continuously outputs CLK 120. So the RATE 210 is terminated at the GATE 400 and the DATA 620 is fixed. Until the next pattern starts, CLR 310 is not outputted from the CLR 300 and previous data are not cleared. Until the next pattern starts, CLR 300 is outputted as CLR 310 and previous data are cleared. These steps are repeated to continuously generate the pattern and the whole block is tested.

Title: Device for hot rolling sheet bar for thin sheet
Inventor: NAKAGAWA KICHIZAEMON
IPC: B21B1/26
Filed: 1983-04-21
Abstract: PURPOSE:To lower the heating temperature of a raw material slab by reducing the temperature drop of a sheet bar, by installing a winding device, a transferring device, and an unwinding device of a hot-rolled sheet-bar between a roughing mill and a finishing mill in a hot rolling devce of a sheet bar for a thin sheet. CONSTITUTION:After removing the scales sticking to a steel slab by a vertical scale breeker 2, while heating the slab by a heating furnace, the slab is rough rolled into a hot rolled sheet bar 10 by a group of roughing mills 4 and is wound up into a coil by a winding device 12. The coil recovers its temperature by its own heat to make the temperature of the whole coil uniform, and the front and rear ends of the bar 10 are settled at almost the same temperatures. The coil is unwound, after inserting it into an unwinding device 14 by a transferring device 16, to remove its scales by a descaler 6 thereby hot rolling it into a sheet bar for a thin sheet by a group of finishing mills 8. Because of the small temperature drop at the rear end of the bar 10 entering the finishing mills 8; the heating temperature of the slab can be lowered as compared with a conventional process, and an energy required for heating the slab is saved.

Title: Controlling circuit for fan motor
Inventor: OKUI ISAMU
IPC: H02P7/288
Filed: 1986-03-31
Abstract: PURPOSE:To improve an air cooling effect while saving labor by inversely proportioning the number of revolution of a motor to supply voltage. CONSTITUTION:A Zener diode 34 supplies a base for a first transistor 32 with stabilized voltage. Resistors 38 and 39 provide a base for a second transistor 33 with voltage obtained by dividing the voltage of a DC power supply 1. The first transistor 32 is mounted to a radiator plate for load. Consequently, a fan motor 31 is not turned or is rotated at low speed on the no-load or light-load of the DC power supply l. When load currents increase and the voltage of the DC power supply l drops, on the other hand, the base voltage Vb of the second trarsistor 33 is lowered and the collector currents of the transistor 32 are augmented, and the number of revolution of the fan motor 31 is increased in inverse proportion to supply voltage.

Title: Pressure sensor
Inventor: SHOJI MASATO
IPC: G01L9/16
Filed: 1989-03-23
Abstract: PURPOSE:To achieve a higher temperature characteristic by providing a non- deformation part of a body with a pressure chamber of a deformation part and a hollow part as well. CONSTITUTION:A pressure is transmitted to a pressure chamber 3 at a pressure introduction port 2 to apply a pressure in such a direction as to expand the chamber 3. As a result, a deformation part 4 is deformed, causing an amorphous magnetic alloy 7 to deform as fastened on the surface thereof. With the deformation thereof, a magnetic permeability of the alloy 7 changes by a reverse magnetostrictive effect. This change of the permeability is detected with a pressure detection coil 8 as change in inductance and a pressure is obtained by taking a difference from a differential coil 9 with a detection circuit 3. A non-deformation part 5 is provided with a hollow part 6 as large as the pressure chamber 3 to make the part 4 the same as the part 5 in structure. Thus, when the alloy 7 is bonded at a high temperature, a heat distortion becomes equal between the parts 4 and 5 to equalize the behaviors of both the parts with respect to temperature thereby obtaining a pressure sensor with a better temperature characteristic.

IPC: G01C17/30
Filed: 1980-05-28
Abstract: PURPOSE:To individually and independently detect the component with a north aspect and the component with an east aspect, which are in the azimuth direction, by means of a simple signal processing, by a method wherein an output of a coil driven from a synchronizing motor is synchronously detected. CONSTITUTION:A power source 3 generates a sine wave output, and drives a synchronous motor 2. The axis relation of the synchronous motor 2 to a coil 1 is set so that the outputs of the power source 3 and the coil 1 are in-phase when a device is positioned facing north. The output of the coil 1 is amplified so that an amplitude is made uniform by means of an AGC amplifier 4. A synchronous detector 6 outputs a product of the output of the AGC amplifier 4 and the output of the driving power source 3. A synchronous detector 7 outputs a product of the output of the AGC amplifier 4 and an output of a 90 deg. phase shifter 5. The outputs of the synchronous detectors 6 and 7 are applied to low-pass filters 8 and 9 to produce a component with the north aspect and a component with the east aspect which are in the advancing direction.

Title: Steel strip minimal in occurrence of plane strain at the time of heat treatment and its production
Inventor: SAWADA TOYOAKI
IPC: B21B1/22
Filed: 1988-03-25
Abstract: PURPOSE:To manufacture a steel strip in which uniform hardenability is secured and the occurrence of plane strain due to hardening treatment is reduced by previously forming nicks in the surface to carry out surface roughening at the time of subjecting a high-carbon steel strip to hardening treatment. CONSTITUTION:At the time of applying hardening treatment to a strip of high- carbon steel containing >0.35wt.% C for use in cutting tool material and spring material, nicks running parallel to the longitudinal direction or diagonal or netlike nicks are formed in the surface of the steel strip to 0.1-100mum depth at spaces of <=5mm by using a grinding roll stretching in the direction perpendicular to the longitudinal direction of the continuously traveling steel strip or a grinding roll forming 30-90 deg. angle (theta) of gradient with the longitudinal direction of the steel strip or further using a grinding roll inclined at the same angle (Q1, Q2), by which the surface is roughened. Since the surface is not smooth, heat radiation rate at the surface is uniformized at the time of heating in a heating surface and the whole steel sheet is uniformly heated and, as a result, a heat-treated steel sheet free from plane strain, such as sheet warpage, at the time of hardening can be obtained in high yield.
