Title: Modulator of anti-lock device
Inventor: MITSUIDE YUKIMASA
IPC: B60T13/40
Filed: 1988-12-28
Abstract: PURPOSE:To prevent excessive inflow of air into a back chamber during anti- lock control operation and to prevent excessive rise of pressure in a liquid chamber when an air pressure piston is returned by providing a throttle passage in a communicating path connecting a back pressure chamber of a large- diameter cylinder and an exhaust passage. CONSTITUTION:A back pressure chamber 24 of a large-diameter cylinder portion 20 is connected to an exhaust passage 35 by a communicating path 38, and a throttle passage 44 is interposed in the communicating path 38. Accordingly, air introduced into the back chamber 24 is controlled by the throttle passage 44 to keep excessive air from inflowing into the back chamber 24, so that an air pressure piston 21 will not retreat excessively. Anti-lock control is released, and when a decay valve 32 is closed, the back pressure of the back chamber 24 becomes zero, so that the air pressure piston 21 is just pushed back from its stop position in the advancing direction, but liquid pressure of a liquid chamber 13 will not be increased remarkably.

Title: Magnetic head and its manufacturing method
Inventor: MAEKAWA NOBUAKI
IPC: G11B5/187
Filed: 1990-11-28
Abstract: PURPOSE:To enable stable recording and reproducing by constituting the magnetic head in such a manner that the width of a magnetic head core to be in contact with a magnetic tape is narrowed in the direction of a gap depth. CONSTITUTION:The magnetic head is provided with a head gap 1, a head notch 2 made of glass, a head sliding direction surface 3 and a coil 4. Then, the core width 5 of the head tip 1 is shaped to be narrowed in the direction of the gap depth. Consequently, even when abrasion of the head is progressed after using the magnetic head for a long time, and a radius of curvature in the head sliding direction is enlarged, floating of the tape can be diminished provided the core width is narrower than the initial case. By this method, contact between the head and the magnetic tape is kept stable, and good recording and reproducing are feasible.
