Title: Anti-skid control unit
Inventor: MATSUDA TOSHIROU
IPC: B60T8/1761
Filed: 1983-11-17
Abstract: PURPOSE:To extend the time until the switchover to the next pressure reduction mode, thoroughly recover a liquid with a pump, and quickly reduce the pressure under the pressure reduction mode by forcibly switching to a hold mode for a fixed time in the middle of a pressure boost mode. CONSTITUTION:When the wheel acceleration/deceleration speed alphaw reaches a preset deceleration b1 due to an increase of the brake liquid pressure, the output of a comparator 18 is increased to H. As a result of an H output of the comparator 18, the input B of the first timer 48 of a timer 24 is decreased to an L level to activate it, and an H signal is outputted. An EV valve 5 is closed for a fixed time due to the H output of this timer 24, and the liquid is sealed in a wheel cylinder and is kept at a fixed liquid pressure. When the output of the timer 24 is cut off, the pressure boost mode is again resumed. Accordingly, by having a hold mode for a fixed time in the middle of the pressure boost mode, the time until the next pressure reduction mode is extended, and the recovery time of the liquid from the wheel cylinder by a decompression pump can be thoroughly secured, thus the pressure reduction control in the pressure reduction mode is performed quickly.

Title: Lead titanate and its precursor, and production of lead titanate
Inventor: KINUGASA MASANORI
IPC: C01G23/00
Filed: 1989-08-21
Abstract: PURPOSE:To obtain lead titanate comprising fine and uniform particles with low flocculation property with using a cheap material by mixing and bringing into reaction an amorphous titanate oxide compd. and lead oxide by mechanochemical method to obtain a specified state and then baking the mixture. CONSTITUTION:An amorphous titanate oxide compd. and lead (II) oxide are mixed to react mechanochemically till the mixture shows an amorphous state by a X-ray diffraction profile and an exothermic peak at 400-495 deg.C by a differential thermal analysis curve. Then the reaction mixture (precursor) is baked at <=495 deg.C to obtain lead titanate having <=0.2mum particles size. This powder obtained by baking the precursor of lead titanate at <=495 deg.C is a simple substance of lead titanate shoeing no peak of impurity such as lead oxide by the X-ray diffraction pattern. Since the lead titanate is baked at low temp., growth of particles is limited and has low flocculation property compared to lead titanate baked at high temp.

Title: Inspecting device for trolley line
Inventor: SAKURAI SHIGEMI
IPC: B60M1/00
Filed: 1983-11-15
Abstract: PURPOSE:To detect a feeding defect due to the uniform wear of a trolley line, the loosening of a connection part, etc., by connecting a load circuit for inspection nearly equivalent to an actual load and a power source for inspection nearly equivalent to an actual power source to the trolley line. CONSTITUTION:A load circuit 3 is connected between a couple of current collectors 2 which come into sliding contact with trolley lines 1, and the same load current flow in a rated state or actual use state. When a supply current from a constant current source 4a is all supplied to the load circuit normally, a specific voltage VL is developed across the load circuit 3. Therefore, a voltage measuring means 5a sets a voltage value in normal operation and compares the measured result to judge a normal state when the both coincide with each other or an abnormal state when not, thereby checking on the state of the trolley line 1 nearly in the actual use state.

Abstract: PURPOSE:To easily and surely retrieve a short-circuited point on a printed board by supplying the AC signal with a prescribed frequency between the two circuit patterns which are respectively short-circuited among the plural circuit patterns formed on an insulating board. CONSTITUTION:After clips 5 and 5a are connected with the two circuit patterns 7 on the printed board 6, the AC signal with the prescribed frequency is supplied from an AC signal generation circuit 2. And then, by tracing whether or not there is a short-circuited point on the pattern 7 by a probe 11, in the case that there is not a short-circuited point on the pattern 7, the AC signal does not flow on the pattern 7, so that the change of a magnetic field is not detected in the probe 11 and there are no changes in a meter 13. But in the case that there is a short-circuited point on the pattern 7, since the magnetic field is generated along the short-circuited electric current, the magnetic field is detected by tracing with the probe 11, and the intensity is displayed in the meter 13 through a magnetic field detecting circuit 10, then, it is ascertained that the pattern 7 which is located near the probe 11 is short-circuited.

Abstract: PROBLEM TO BE SOLVED: To obtain a spectroscopically split ray of light by avoiding the fluctuation of the spectroscopically split wavelength caused by the temperature fluctuation of a spectroscope element composed of a birefringent crystal by measuring the temperature fluctuation of the element and correcting the frequency of the ray of light by using the difference between the measured temperature of the element and a reference temperature as a frequency controlling and correcting signal. SOLUTION: A temperature measuring element 4 measures the temperature of a spectroscope element 1 composed of a birefringent crystal and outputs a frequency controlling and correcting signal a2 . A frequency controlling signal superposing circuit 5 inputs the signal a2 and outputs a frequency controlling superposing signal a3 by superposing the signal a2 upon a frequency controlling signal a1 . A frequency generating device 3 applies acoustic vibrations to the element 1 by impressing a high frequency generated based on the signal a3 upon a high-frequency vibrator 2.  Since the signal a1 is inputted to the generating device 3 as a superposing signal a3 ' corrected with a correcting signal a2 ' and the generated high frequency is corrected when the temperature of the element 1 detected with the measuring element 4 is higher than a reference temperature, the same spectrally split wavelength as the frequency at the reference temperature is obtained.
