Title: Air spring with built-in preload chamber and pressure reducing chamber
Inventor: OKAMOTO AKIO
IPC: F16F9/05
Filed: 1990-05-14
Abstract: PURPOSE:To surely perform air supply action by building a mechanism, in which air, compressed by a preload piston of relatively small suction activity, is once accumulated in a preload chamber and automatically supplied into a pressure reducing chamber as necessary, in an air spring. CONSTITUTION:In an air spring where car height is in a neutral point or less, at each time lower side air pressure is increased larger than the upper side air pressure of a piston 19 in a pressure reducing chamber 21 by repetition of up/down motion of a hollow piston 13, lower side air is drawn out to an upper side via a press-in fine hole 17, ring groove of a pull valve 15 and a flowout fine hole 14. Simultaneously by a preload piston 20, compressed air in a suction chamber 30 is once accumulated in a preload chamber 24 because of high air pressure in the chamber 21, next by changing the piston 13 to be lowered, a ring groove and the fine hole 17 are closed by the valve 15, and at each time a pressure of air in the chamber 21 by its volumetric expansion is decreased lower than the pressure of air in a chamber 24, accumulated air in the chamber 24 is moved into the chamber 21 to return the car height to the neutral point.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic tape cassette and the assembling method of the magnetic tape cassette attaining the improvement of efficiency of the assembling work by preventing a reel spring from floating when the reel spring for pressurizing the tape reel is fixed to a cassette half. SOLUTION: In the magnetic tape cassette 1, a groove part 4 is formed on the upper half cassette 2 and a notch 3d is formed on a base end part 3b of the leaf spring 3 to impart the elasticity in the horizontal width direction. When the base end part 3b is fitted into the groove part 4, the base end part 2b in the horizontal width direction is shortened, and after the insertion, it is restrained to the groove part 4 in the outside direction of the base end part 3b by the elasticity to prevent the reel spring 3 from floating. Consequently, the fixing work of the reel spring 3 is efficiently and accurately performed, then the assembling work of the magnetic tape cassette is efficiently carried out.

Title: Controller for heat sensing recording
Inventor: SAITOU TAKASHI
IPC: H04N1/23
Filed: 1981-08-11
Abstract: PURPOSE:To make the recording density constant, by adjusting energy applied for recording with the change in the ambient temperature of a recording head and the characteristics of the recording head. CONSTITUTION:A voltage corresponding to the temperature around the head main body is outputted from a thermister 1 and a temperature detection section 8 is provided with a plurality of comparators 6 comparing the said voltage with a plurality of threshold values. An output of the said comparators is one input to a storage circuit 9 and a digital signal determined with the characteristics of the recording head is another input and one set of outputs is obtained from a storage circuit 9. This output presets a counter 13. In this case, the carry signal of the counter 13 is at low level and the output of an inerter 15 is at high level. This introduces an enable signal to count a clock CK2. When the count value reaches a preset value, a carry signal is produced to stop the counting. Thus, the output of the inverter 15 goes to low level, which in turn makes the output of an AND circuit low in the level, allowing to stop the driving of the head.

Title: Magnet type measuring method for strain
Inventor: FUKUI KIYOSHI
IPC: G01B7/24
Filed: 1979-09-29
Abstract: PURPOSE: To enable measurement of the absolute value of tensile strain and compression strain by pressing the magnetic poles of a U-shaped iron core with input and output coils wound round it upon a surface whereon the measurement is performed in such a manner that the poles are positioned at a right angle to the loading direction of a metal material to be measured.  
     CONSTITUTION: Magnetic poles 4 and 5 are formed by winding an input coil 1 and an output coil 2 round the U-shaped iron core 3. The coil 1 is connected with an oscillator which gives the alternate voltage of proper frequency thereto, while the coil 2 is connected with a detector for detecting the output. The magnetic poles 4 and 5 are pressed on a surface 7 whereon the measurement is performed in such a manner that the U-shaped plane of the iron core 3 has the direction B-B perpendicular to the loading direction A-A. By this constitution, the magnetic permeability of a metal material 6 changes rectilineally in proportion to the magnitude of the stress generated through the change in the tensile load as shown in the figure. The compression load also brings about similar change, although the direction thereof is reverse. Therefore, the absolute values of tensile strain and compression strain themselves can be measured.

Title: Device for controlling elevator
Inventor: YONEMOTO MASASHI
IPC: B66B1/28
Filed: 1988-05-24
Abstract: PURPOSE:To carry out a power saving operation without deteriorating operation efficiency by providing a means of measuring the generating interval of calls, a means of judging the operating pattern of an elevator, and a means of setting the speed command value of the elevator and carrying out the power saving operation only when a long story floor operation is feasible. CONSTITUTION:Generally, since calls are always generated at the time of operating an elevator with high frequency, the central arithmetic unit 2a of a speed command device 2 carries out the control of ordinary operating times. On the other hand, when the number of riders is reduced causing the operating times of the elevator to be lowered, the number of calls is also reduced. In this case, the generating interval (T) of the calls is detected. Then, by comparing this call generating interval T with a previously set defined value (T0), when T>T0, it is determined to be a slack hour and, when a full speed operation is feasible, a speed command with a lowered acceleration is generated to carry out a power saving operation. Particularly, at the time of operating between long story floors, since the full-speed traveling term is longer than an accelerating/ decelerating term, the increase in traveling time caused by the reduction of acceleration is small.
