Title: Exhaust particulates treatment equipment of internal-combustion engine
Inventor: USHIMURA MASAHARU
IPC: F02M63/00
Filed: 1983-12-15
Abstract: PURPOSE:To facilitate fuel injection quantity control in an equipment which is provided with both a burner device burning exhaust particulates and a fuel injection valve supplying the burner device with fuel, by mounting a valve by which the pressure of fuel fed to a fuel injection valve may be maintained to be a specified pressures. CONSTITUTION:A fuel passage 24 which is communicated with a pump chamber 23 is formed in the overflow outlet part 21a of a fuel injection pump 21 and communicated with both a fuel supply passage 20 connected to a fuel injection valve and a return passage 25 returning excess fuel into a fuel tank. A passage 28 which communicates the lower end part of the fuel passage 24 with the lower stream of the overflow orifice of the return passage 25 is also formed in said part 21a. A ball valve body 30a which closes the passage 28 by the force of a spring 29 is disposed in the passage 28, thereby making up a pressure regulating valve 30. The valve 30 opens the passage 28 if the pressure of fuel in the fuel passage 24 exceeds the specified value, and permits fuel to be flown into return passage 25 so as to maintain the pressure in the fuel passage 24 to be specified value.

Title: Reliability guarantee testing method for high-temperature long-life strength of ceramic parts
Inventor: USAMI SABURO
IPC: G01N3/00
Filed: 1985-10-23
Abstract: PURPOSE:To secure the reliability of the high-temperature long-life strength of a ceramic component without any nondestructive inspection by taking a guarantee test which utilizes a static fatigue limit at in-use test and the defect size dependency of low-temperature, short-time strength. CONSTITUTION:When a guarantee test of the root part 2 of the ceramic component 1 is taken, a temperature raising means 3 heats the ceramic components 1 uniformly up to 800 deg.C where this material has almost no static fatigue. A solenoid valve 5 is opened and pressurized water is blown to the root part 2 from a porous nozzle 6. The stress reaches 405MPa while the solenoid valve 5 is left open, but when the solenoid valve 5 is closed when the stress reaches 330MPa slightly higher than 320MPa, the stress decreases speedily. If no breaking sound is detected by an acoustic emission sensor 9 in the process of this guarantee test, the component is acceptable and when a sound is detected, the component is defective.

Inventor: TAKEHARA KIYOTAKA
IPC: H04M1/64
Filed: 1983-12-14
Abstract: PURPOSE:To improve the effect of crime prevention without giving any unpleasant feeling to a caller by opening a line if the voice from the caller is not detected even after the voice response is repeated after the closing of the telephone line in an automatic answering device of an user's telephone set. CONSTITUTION:When a call signal is incoming, a control section 2 detects it and transmits it to a control circuit 5, then a line closing signal is fed to the control section 2, which closes the telephone line 1. Then a response message is transmitted for a prescribed number of times from a voice response section 6, a changeover switch 8 is switched during the period when no response message is transmitted and the response from the caller is awaited. When the voice of the caller is incoming, the voice response section 6 transmits the automatic answering message. If no response comes from the caller, the telephone line 1 is opened. In using a voice by means of reproduction of a tape, the caller cannot recognize it as the voice from the automatic answering device only with listening to the voice response.

Abstract: PURPOSE:To process a work highly precisely into a desired shape by setting a product of a signal corresponding to a distance between a tool moving means and a face to be cut and a positive coefficient less than 1 as a correction signal and moving the tool moving means based on the correction signal. CONSTITUTION:In cutting processing, a distance between a tool moving means 8 which relatively moves a cutting tool 5 and a work 3, and a face to be cut 3a which is cut by a cutting tool is measured by a measurement means 4.
