Patent JP-H02264521-A (JP)
Title: Moving quantity detector
Inventor: ISHII SATORU
IPC: G01D5/36
Filed: 1989-04-03
Abstract: PURPOSE:To allow the detector to output a stable output up to a DC region and to respond to up to a high frequency region by providing a 1st amplification means amplifying a low frequency component, a 2nd amplification means amplifying a high frequency component, and an adder means synthesizing outputs of both the amplification means. CONSTITUTION:A signal detected by a photodiode 4 is converted into a voltage by a resistor 6, a low frequency component of an electric signal is amplified by a 1st amplification means 7 and a high frequency component of the electric signal is amplified by a 2nd amplification means 9. Then outputs of the means 7, 9 are added by an adder means 10 and the resulting output is outputted. In this case, the sum of the transfer functions of the means 7, 9 is nearly a real number in the vicinity of the frequency where frequency bands cross together. Moreover, when the electric signal in response to the moving quantity and moving speed of an object has a sufficiently lower frequency than the cross point of the frequency band, the output of the means 9 is not added. Thus, the stable characteristic up to the DC region is attained and response up to a high frequency region is obtained.

Title: Diaphragm setting device in case of flash photographing
Inventor: TAKAGI MASAAKI
IPC: G03B7/16
Filed: 1983-05-16
Abstract: PURPOSE:To make a special mechanism unnecessary for setting a diaphragm at the time of a flash photographing by providing opposingly a light emitting element on a field luminance detecting photodetector, and setting its light emitting quantity by a distance and a film sensitivity. CONSTITUTION:A light emitting element LED2 is provided opposingly to a field luminance detecting photodetector SPD, and a driving current of the light emitting element is set by a distance operating circuit LO. At the time of a flash photographing, switches S2, S3 are closed, and the light emitting element emits a light by the driving current corresponding to a distance. As a result, the emitted light is made incident to the photodetector through a light guide 2 and a photodetecting diaphragm 3 interlocking with opening of a diaphragm-combined shutter, and the collector potential of a transistor Q3 drops following the opening of the shutter. When this potential reaches a prescribed value, a comparator CM2 is inverted, a flash light is emitted, and the shutter is closed.

Title: Improvement of ground
Inventor: FUKAYA KAZUO
IPC: E02D3/12
Filed: 1983-05-16
Abstract: PURPOSE:To prevent the poor joining of the already improved soil with newly improved soil by a method in which when a cement-based hardening agent slurry is injected into soft ground and mixed the ground by stirring, the temperature of the improved soil immediately after being mixed is kept lower than that of the soft ground in such a way as to keep the initial period strength of the ground low. CONSTITUTION:When a cement-based hardening agent slurry is injected into soft ground and mixed with stirring, the temperature of improved soil immediately after being mixed is kept lower than that of soft ground by means of a cooler. In this case, the temperature of the improved soil is kept at 10-15 deg.C preferably. Since the development of the initial-period strength of the improved soil can be temporarily suppressed, the poor joining of the already improved soil and newly improved soil damage to the construction machine can be prevented.

Namely, '1' is simultaneously written in respective banks, their outputs are turned to a negative mode, data for respective banks are read out, and when all outputs are '0', the banks are decided as normal. When all the outputs are not '0', the existence of a defective position is judged.

Abstract: PURPOSE:To make magnetic flux density high on a part where a seal is formed by restraining toner and to surely prevent the toner from leaking at a low cost without especially enhancing accuracy on process and assembling by magnetically connecting a magnetic sealing member to a magnet roller and forming a magnetic circuit. CONSTITUTION:Since the magnet roller 7 extends outside the toner carrying part of a sleeve 4, the toner leaking toward a side part enters a gap part between the end edge of the magnet roller and the annular part 10a of the seal member 10. The magnetic flux exists on the gap part between the end edge of the roller 7 and the annular part 10a of the member 10 with high density, the toner reaching the part is controlled to be accumulated. In this case, the magnetic flux generated from the roller 7 is converged on the annular part 10a of the member 10, then is returned to the roller 7 through a connecting part, the annular part, and a shaft part 7a. Consequently, magnetic resistance can be made small by adequately setting saturated magnetic flux amount on the connecting part and the annular part.
