Title: Flow control valve for antilock
Inventor: NOKUBO SEIJI
IPC: B60T8/40
Filed: 1988-09-24
Abstract: PURPOSE:To prevent the sticking of a piston due to the rusting thereof by causing a relative shift between the spool and the enclosure thereof via the operation of a movable body on every brake operation with brake fluid pressure. CONSTITUTION:A flow control valve 103 is so constituted that the one end thereof having a small diameter is inserted in the spool housing chamber of an enclosure 31, and kept in contact with the front end of a spool 32 in a direction energized with a spring 34, and the other end having a large diameter is provided with a piston 10 inserted in a piston chamber 12 and a spring 11 for detaching the piston 10 from the spool 32 for being retained with the force of the spring 11 during the non- application of braking operation. At the time of braking operation, the piston 10 is shifted down by a stoke of L on a fluid pressure differential working on both ends thereof and the spool 32 is forcibly moved toward the side of a decompression chamber 36 by the same distance as the piston 10. Both pressurized faces of the piton 10 are continuous to each other via an internal passage 10a. When the pressurized area differential of both ends is so determined as to obtain piston thrust overcoming the force of the spring 11 during the application of relatively low braking pressure Pn, the operation of the valve 103 is ensured even in non-antilock operation. According to this construction, it is possible to prevent the sticking of the piston 10 due to the rusting of the spool 32.

CONSTITUTION:A book 1 is placed on a book cassette 2 mounted on an original platen 5 with the copied face (f) facing upward. When a copy command switch is depressed, the original platen 5 starts moving at uniform speed. During the process, the distance between a distance measuring instrument 7 and the copied face (f) of the book 1 is measured by the distance measuring instrument 7. In this case, an arithmetic means that calculates the rate of change of distance from the reference plane of image forming of the original by the output of the distance measuring means and positional information of the direction of exposure scanning of the distance measuring means and a charge erasing means that erases the charge of an area on the photosensitive body corresponding to the area of large rate of change that does not required copying are provided. At the same time, the relative movement of an original mounting means and an original illuminating means is made possible.

Title: Spatter preventing method of consumable electrode type arc welding
Inventor: SUZUKI HIROSHI
IPC: B23K9/00
Filed: 1984-11-14
Abstract: PURPOSE:To prevent effectively the generation of a spatter even within the range of a welding current pulse frequency, in which the generation of a spatter is hardly prevented, by giving an ultrasonic oscillation to a welding wire being a consumable electrode in case of a consumable electrode type arc welding. CONSTITUTION:An oscillation is given indirectly to a welding wire 1 by attaching an ultrasonic wave oscillator 7 to a wire guide 3 incorporated in a welding torch 2. Even in case of a one pulse one droplet welding by a conventional pulse power source, the generation of a spatter increased suddenly in a range in which a pulse frequency is other than 200-300Hz. By giving the ultrasonic oscillation, the generation of a spatter is lowered within the range of 200-300Hz, and it is lowered enough even in other range. In this regard, the ultrasonic wave oscillator 7 can be attached to the wire guide 3 placed near the torch 2, too.

In addition, inductance is obtained from the detected electric angle, coil resistance is obtained from the inductance value and the measured current value, and the coil temperature is estimated based on the coil resistance value. If an error between the estimated coil temperature and the coil temperature measured by the thermistor 80 exceeds a predetermined value, abnormality occurring in the thermistor 80 is determined.
