Title: Pneumatic safety radial tire
Inventor: KAWABATA MISAO
IPC: B60C17/00
Filed: 1992-02-21
Abstract: PURPOSE:To promote the facilitation of judgment in the presence of flat tire running hysteresis by installing a marker of the flat tire running hysteresis in an inner part of side rubber nearby an inside surface or outside surface or outer surface of a sidewall part where grounding occurs in the state that a tire is punctured. CONSTITUTION:A marker layer 9 of flat tire running hysteresis, where a property of the sidewall part 7 is varied if it grounds in a state of being punctured and receives a strong compressive strain, is installed in the inside surface of this sidewall part 7. Therefore, the presence of flat tire running is easily discrinable from appearance, thus safety management for high speed running is achievable in this way.

Title: System for controlling magnetic bubble memory
Inventor: KANEKO KEIICHI
IPC: G11C11/14
Filed: 1982-03-08
Abstract: PURPOSE:To prevent malfunction at the time of releasing the power-on reset, by controlling the power-on reset circuit of a magnetic bubble memory circuit with a clock generator. CONSTITUTION:When the voltage (1) gradually is increased and reached a specific voltage VREF after making an input power supply, the gate of a power-on reset circuit 8 is opened and a voltage (2) is outputted. A clock generator 9 starts the operation simultaneously with the making of the power supply and outputs a clock pulse (3). Disturbed pulses at the initial stage are cut (4) by an NAND gate 13 and counted by a counter 14, and, after the number of clocks N required for making the power-on set for returning a sequencer, etc., to the  initial stage is counted, a power-on reset release signal (5) is delivered, and  thus, the normal operation is started. In this way, malfunction at the time of  power-on is prevented.

Filed: 1989-02-15
Abstract: PURPOSE:To allow the easy analysis and measurement utilizing a piezoelectric element by integrating the piezoelectric element and a container for a sample to be inspected to a cylindrical shape in appearance. CONSTITUTION:The test tube-shaped container 1 made of plastic has the structure to allow division to two parts, upper and lower. An AT-cut crystal resonator 2 is inserted therebetween and is fixed by a resin. An electrode A3 is provided on the surface in contact with a soln. on the AT-cut crystal resonator 2 and an electrode B 4 on the surface not in contact with the soln. The outside wall of the container 1 is provided with a measuring instrument connecting terminal B 6 for connecting the electrode A 3 and a measuring instrument connecting terminal A 5 for connecting the electrode B 4. Only the one surface of the piezoelectric element eventually comes into contact with the sample to be inspected when the sample to be inspected is put into the container 1. The piezoelectric element is changed in its resonance frequency and loss resistance by receiving the influence of the viscoelasticity and density of the material in contact with the surface of the element and a weight change, such as adsorption of the material onto the surface. The viscosity, etc., of the sample to be inspected are, therefore, measured by measuring the resonance frequency and loss resistance.

Title: Control device for turbine bypass valve
Inventor: KAMIKASEDA KOUICHI
IPC: F01D17/00
Filed: 1987-02-20
Abstract: PURPOSE:To make it possible to maintain pressure in a factory steam system stably, by memorizing the total flow of main steam in the normal operation and controlling a turbine bypass valve to make that total flow of main steam to flow into a turbine bypass line in the case of a turbine trip. CONSTITUTION:When a trip of a back pressure turbine 3 occurs in a steady operation of the back pressure turbine 3, an adjusting valve 2 is wholly closed by a control device which is not indicated in the illustration, a timer 74 is started and a switch 72 is changed over to (b) side during a certain time. In this time, a flow detector 8 detects zero of a steam flow and an output of an adder 752 which adds this detected signal to a signal which indicates a flow of turbine bypass steam and comes from an opening/flow converter 751, goes down drastically, but the above output is output to a turbine bypass valve 5 by the function of a delay unit 753 after being delayed a preset time. Thus the total flow of steam before the occasion of the turbine trip is allowed to flow into the turbine bypass line and a flow of steam to a factory steam system is maintained at a constant flow level.
