Patent JP-H03161113-A (JP)
Title: Extrusion press apparatus
Inventor: MAEDA TAKUMA
IPC: B21C23/21
Filed: 1989-11-17
Abstract: PURPOSE:To reduce the retreating time of a ram, to reduce the idle time and to improve the working rate by connecting a hydraulic oil pulling-out valve with the rear of an extruding cylinder. CONSTITUTION:Hydraulic oil pressure in the extruding cylinder is extruded by opening and closing small-sized valves V9 and V10 used exclusively for extruding pressure especially without opening and closing a prefill valve 66. Besides, since the hydraulic oil pressure can be introduced by opening a valve V12 in the same way as the valves V9 and V10, the backward and forward movement of the ram 58 can be carried out smoothly in a short time. In this way, the idle time can be reduced.

Title: Gps receiver
Inventor: KIDA HIROYUKI
IPC: G01S19/36
Filed: 1994-11-08
Abstract: PURPOSE: To reduce the size and cost of a fault diagnosing function which detects the fault of a GPS receiver by detecting the internal temperature of the receiver by estimating the internal temperature by detecting the deviation of the oscillation frequency of a crystal oscillation circuit on the basis of electric waves from a GPS satellite. CONSTITUTION: When the oscillation frequency of a crystal oscillation circuit 4 is measured based on the frequency of an intermediate-frequency signal contained in electric signals received from a GPS satellite by inputting the oscillation frequency of the circuit 4 which is not compensated in temperature to a receiving processing section 3, the deviation of the oscillation frequency of the circuit 4 can be detected. The internal temperature of a GPS receiver is estimated by inputting the deviation of the frequency to a receiver temperature estimating section 5 and estimated temperature is sent to an abnormality detecting and warning section 6.  When it is estimated that the temperature estimating information sent from the section 5 is deviated from a prescribed temperature zone, for example, from -10 deg.C to 40 deg.C, the section 6 discriminates that a fault occurs in the receiver and issues a warning by actuating an alarm, etc. Since the self-diagnosing function is constituted by utilizing the software of a CPU, the number of circuits to be added can be minimized.

Filed: 1990-11-06
Abstract: PURPOSE:To obtain easily desired anisotropic water permeability by constraining the direction that the coefficients of permeability must be reduced in concrete structures having the different coefficients of permeability in the mutually orthogonal directions while mixing an additive and generating gas. CONSTITUTION:The direction that the coefficient of permeability must be made smaller than others is constrained by a pair of form boards 10. Aluminum powder is added together with cement, water and aggregate, thus acquiring placing concrete. When concrete C is placed between the form boards 10, aluminum powder and calcium hydroxide in concrete C are reacted chemically, and hydrogen gas is generated. The hydrogen gas is moved in the direction that it is not constrained by the form boards 10, and fine capillary air gaps are formed, thus increasing the coefficient of permeability. Accordingly, a concrete structure having desired anisotropic water permeability can be manufactured easily by the normal kneading of concrete.

CONSTITUTION:Voltage in proportion to the drop voltage of a resistor R1 due to load current is set to be applied to an electricity quantity estimation recorder 15, and when the load current flowing to the resistor R1 is changed, then the drop voltage of the resistor R1 is changed, and the applied voltage of the electricity quantity estima tion recorder 15 is also changed. For example, when the load current is greatly used on shaving off heavy whiskers or on pushing a face strongly against a shaver, then the drop voltage of the resistor R1 is increased, and so the applied voltage to the electricity quantity estimation recorder 15 is also increased, and the moving quantity of electrolyte 11 for showing an estimation time is increased. In other words, when the load current is increased and a shaving cutter is quickly consumed, then an estima tion quantity according to it is increased, and the exchanging time of the external shaving cutter 8 of the shaver can be specified more properly.
