Title: Earthquake-resisting wall
Inventor: MATSUI CHIAKI
IPC: E04H9/02
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent the shearing bending due to a horizontal load, and to easily adjust the yield strength to the shearing force and the bending rigidity in the horizontal direction. SOLUTION: A steel plate 3, which is connected to an upper and a lower large beams 2 forming a framework of a building, is provided with plural slits 4 extended in the vertical direction. Since an intermediate part of the steel plate 3 is divided by the slits 4, bending yield strength to the shearing bending yield strength is reduced so as to prevent the shearing bending of the steel plate 3, and the stabilized restoring force characteristic after the yielding can be obtained. Since the yield strength and the rigidity can be easily adjusted by changing plate thickness of the steel plate 3, and width, length, number and space of the slits, design of the structure in consideration of the vibration characteristic of the framework can be easily performed.  Consequently, the structure is simplified, and its manufacture is facilitated, and work executing properties are improved because of the steel plate wall.

Abstract: PURPOSE:To secure the stable brake feeling in which the brake releasing time point is fitted with each road surface by detecting the deceleration speed of a chassis due to the start of brake and correcting the set level according to the chassis deceleration speed. CONSTITUTION:The speed of a wheel 4 on brake application for a car is detected by a wheel sensor 8, and the acceleration/deceleration speed is obtained by an electronic control unit 12 on the basis of the detected value, and when the acceleration/deceleration speed exceeds a set value, an instruction 11 for suppressing a wheel brake 5 is outputted. The brake power is adjusted by driving the actuators 3a, 3b, and 3c of a driving means. When the chassis deceleration speed detected by a chassis deceleration speed detecting means increases, the set level is corrected to a large value by a correcting means. With such constitution, on a high frictional road surface, the set level increases, and the gentle control fitted with the brake state is performed, and on a low frictional road surface, the set level reduced, and the gentle control fitted with the brake state is performed.

Abstract: PURPOSE:To remove an error in measurement and the lowering of sensitivity by a method wherein at least a part on a signal optical path and a reference optical path exposed in a space wherein a magnetic field is measured is constructed of a conductively-covered fiber and a conductive cover of the fiber on the signal optical path is electrified by an alternating current. CONSTITUTION:A construction is made in such a manner that a magnetic field sensing part 3 of a Lorentz force type is provided on a signal optical path of an interference system, while a reference fiber part 4 in the same condition as the above is provided on a reference optical path, and a current for measuring a magnetic field is applied to a conductive cover of the sensing fiber part, while no current is applied to the conductive cover of the reference fiber part. In this construction, the sensitivity to the magnetic field is generated only in the sensing fiber, but the sensitivity to disturbance, such as vibration or temperature, other than the magnetic field is equal both in the sensing fiber and in the reference fiber. Accordingly, an effect produced by the disturbance, such as the vibration or the temperature, other than the magnetic field is offset in the interference system, and only the effect of the magnetic field can be obtained as an output of the interference system.

Title: Digital phase comparison method
Inventor: TSUCHIYAMA YOSHIRO
IPC: G05D13/62
Filed: 1985-12-18
Abstract: PURPOSE:To increase the loop gain of a phase control system by obtaining the arriving time intervals of reference signals to convert them into the time intervals of the frequencies of the PG signals obtained by a rotary phase detector PG and calculating the arriving time point of the reference signal to define the difference between both arriving time points as a phase difference. CONSTITUTION:A digital phase comparator of a VTR, etc., consists of a 1/4 divider 21, a triple multiplier 22, a sawtooth wave generator 23 and a sample holding circuit 24. A rotary head drum 26 is driven and controlled by a speed control circuit 25. The rotary phase is detected by a detector 27 and supplied to the circuit 24. Then the generator 23 is reset by the signal obtained by dividing the vertical synchronizing signal by the divider 21 and multiplying it through the multiplier 22. Thus the sawtooth waves are obtained. These sawtooth waves are sampled/held by the PG signal sent from the detector 27 and the phase error value is obtained. This error value is sent to the circuit 25 for modulation of the speed reference signal. Thus it is possible to perform the phase comparison with the frequency of the PG signal, as it is.

Title: Satellite broadcast receiver
Inventor: HOSOKAWA HIROHISA
IPC: H04N5/44
Filed: 1990-10-22
Abstract: PURPOSE:To improve the operability by providing a signal presence or absence discrimination means discriminating the presence or absence of a broadcast equivalent to a receiving channel to the receiver and selecting only a channel discriminated to have a broadcast. CONSTITUTION:When a channel-up key is depressed while an 11th channel is selected, a control section 19 selects at first 13th channel and checks an output of a voltage comparator 23 to discriminate the presence or absence of a broadcast. Since the 13th channel has not broadcast at present, the voltage comparator 23 outputs a signal representing the absence of broadcast. The control section 9 judges the absence of broadcast and selects a succeeding channel, i.e., 15th channel. Since the 15th channel has a broadcast, a signal representing the presence of broadcast is outputted. The control section 9 judges the presence of broadcast and stops the channel selection while selecting the 15th channel.

Abstract: PURPOSE:To prevent the deterioration of the picture quality of radiation pictures by scattered radiations by taking the radiation picture of an object by placing a structure constituted of alternately arranged radiopaque and radiotransparent members between the object and a stimulable phosphor and correcting the reading value of the shadow part of the radiotransparent members near the shadow part of the radiopaque members on the basis of the reading value of the shadow part of the radiopaque members. CONSTITUTION:A structure 4 constituted of alternately arranged radiopaque members 2 and radiotransparent members 3 is placed between an object 12 and stimulable phosphor 1. At the time of reading the latent image formed in the phosphor 1, the amount of scattered radiations reaching the part of the phosphor 1 in the shade of the radiopaque members 2 is found directly or through prescribed arithmetic operation from the reading value of the part. Then the found amount of scattered radiations is subtracted from the reading value of the shadow part of the radiotransparent members 3 near the shadow part of the members 2. Therefore, clear radiation pictures can be obtained by removing the influence of the scattered radiations from the reading value of the stimulable phosphor 1.
