Title: Control valve of departure clutch
Inventor: SHIMAMOTO MASAO
IPC: F16D48/02
Filed: 1985-02-09
Abstract: PURPOSE:To control for smooth departure without shock by acting clutch back pressure and solenoid pressure in the mutually opposite directions with respect to a spool, and making the land diameter of the spool receiving the clutch back pressure larger than that of the spool receiving the solenoid pressure. CONSTITUTION:During stopping, a solenoid 40 is turned off, so that low oil pressure balanced with the spring force of a spring 13 acts upon a piston chamber 7 of a departure clutch 1 through an oil path 33.

Title: Floppy disk drive control system
Inventor: AKASHI KAZUO
IPC: G11B19/00
Filed: 1983-02-16
Abstract: PURPOSE:To prevent the service life of a floppy disk from being waste uselessly by the constitution that an idle seek is executed periodically or unperiodically to a floppy disk driving FDD other than a designated objective in the processing to the designated floppy disk driving FDD. CONSTITUTION:Suppose that a command taking an FDD5 as an FDD processing objective is given to an FDC4. The FDC4 discriminates the propriety of a given command, and when the discrimination is YES, whether or not an idel seek flag is set is discriminated. This flag is set in the timer processing routine in the FDC4 and this routine is started by an interruption signal generated at each prescribed time from a programmable timer 3. When it is discriminated that the flag is set, the FDC4 designates an FDD6 being other than the processing objective and discriminates whether or not the current track of the FDD6 is the innermost circumference track, and when it is NO, the FDC4 makes the FDD6 seek a track inward by one track and when YES, the FDC4 makes the FDD6 seek a track outward in the outermost circumferential position. Then, the FDC4 returns the drive from the FDD6 to the FDD5, thereby applying processing corresponding to the command. Thus, the disk is not run for a long period on the same current track.

Title: Semiconductor device
Inventor: YANAGA MASATAKA
IPC: H01L23/28
Filed: 1986-02-06
Abstract: PURPOSE:To improve the bondability of a resin to a heat sink plate, to strengthen against a mechanical stress and a thermal stress and to further improve moisture resistance of a semiconductor device by forming a groove having a contracted portion narrowed in the width of the groove in a lateral sectional shape in the heat sink plate. CONSTITUTION:A semiconductor element is placed apporoximately at the center on the upper surface of a heat sink plate 1, the semiconductor element 3 is connected via fine metal wirings 5 with leads 4, and sealed with resin 6. A groove 2 is formed to surround the placing portion of the element 3 on the plate 1, and the lateral sectional shape of the groove 2 is narrowed in an inlet, widened in the width of the groove in a deep portion and contracted in an inlet. Thus, the wide portion of the groove of the deep portion is suppressed in the sealing resin in the depthwise direction of the groove to strengthen the bonding strength of the plate 1 to the resin 6. Since the bonding strength of the resin 6 to the plate 1 is thus increased, the invasion of water immersed from the boundary between the resin 6 and the plate 1 is decelerated, and even if a mechanical stress and a thermal stress are applied to a semiconductor device, it can prevent the resin and the plate from displacing in the depthwise direction of the groove.
