Title: Controller for brake booster and recording medium
Inventor: OOKA MASAKI
IPC: F02D29/02
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a controller for a brake booster and a recording medium capable of ensuring the negative pressure of the constant pressure chamber of the brake booster without causing a problem such as an engine stall upon start at low temperature or when the load of an engine such as an air conditioner is large. SOLUTION: In step 120, an ordinary ISC controlled variable DISC is calculated. In step 130, the negative pressure of an engine is low, so that a booster negative pressure deciding process is carried out to decide whether or not the negative pressure of a booster is low. In step 140, in order to increase or decrease the quantity of intake air, a DISC correction process is carried out for correcting the ISC controlled variable DISC. In step 150, a process is performed for outputting the ISC controlled variable DISC corrected by the DISC correction process. The opening and closing state of an ISC valve 19 is adjusted corresponding to the output value of the ISC controlled variable DISC to control the increase or decrease of the quantity of auxiliary air.

Title: Corona discharge wire
Inventor: OKABE YASUSHI
IPC: H01T19/00
Filed: 1989-11-20
Abstract: PURPOSE:To allow the execution of a corona discharge with a low impressed voltage by providing projecting parts on the outer periphery of the corona discharge wire. CONSTITUTION:The corona discharge wire 5 for executing the corona discharge by receiving a high voltage has the projecting parts 5b on the outer periphery. This corona discharge wire 5 makes corona discharge toward an object when the voltage is impressed thereto. Since the front ends of the projecting parts 5b provided on the outer periphery of the wire has the radius of curvature smaller than the radius of curvature of the outer periphery of the wire, the discharge is executed from the front ends of the projecting parts 5b. Thus, the corona discharge is eventually started with the lower voltage than with the corona discharge wire which is not provided with the projecting parts.

Title: Defect detecting device for shield layer of shielded electric conductor
Inventor: IGARASHI MIKIO
IPC: G01R31/02
Filed: 1986-12-20
Abstract: PURPOSE:To detect the defect of a shield layer automatically by applying an AC signal between a core conductor and the shield layer and detecting a leak signal, and comparing the detected AC signal level with the signal level of a specific reference voltage source. CONSTITUTION:The AC signal generated by amplifying the output of an oscillator 52 by an amplifier 53 up to a specific level is supplied to between the core conductor 4 and shield layer 6 of a shielded electric conductor 1. Here, if the shield layer 6 has a defect 6' owing to the trouble of a manufacturing device and there is a part where the outer periphery of an insulating coating 5 is not covered, the AC signal supplied to the core conductor 4 is not cut off by the shield layer 6, but leaks much to the side of a detection electrode 71, which generates a large-level signal. The level of the input terminal IN of a comparing circuit 74 rises and the circuit 74 generates an output, which turns on a warning lap 76 and also generates a contact signal 77. Thus, the defect of the shield layer in the manufacture line of the shielded electric conductor can be detected automatically.

Title: Scale removing method of steel
Inventor: KONDO YASUMITSU
IPC: C21D1/82
Filed: 1999-10-25
Abstract: PROBLEM TO BE SOLVED: To efficiently remove surface oxide scales of a hot worked steel and a heat treated steel such as a hot rolled steel plate without any pickling like a conventional method, or considerably reducing the load in the pickling. SOLUTION: The steel having oxide scales of >=5 μm in thickness is cooled by passing its Ar3 transformation point at the cooling speed of >=10 deg.C/sec. The steel having the oxide scale of >=1 μm in thickness is cooled by passing its Ar3 transformation point at the cooling speed of >=10 deg.C/sec. while descaling the steel with the high-pressure water and/or bending the steel at the radius of curvature of <=500 mm. Since scales can be removed during the cooling in hot working facilities or heat treatment facilities, a conventional pickling facility can be dispensed with, or considerably simplified if necessary, and its load is also considerably reduced.
