Title: Method for releasing plastic molded foam
Inventor: SASAKI KISOZOU
IPC: B29C33/46
Filed: 1987-02-02
Abstract: PURPOSE:To easily release a plastic molded foam at low cost without noise by a method wherein air is blown in a hole, which is bored almost at the center of the plastic molded foam and covered with an air nozzle. CONSTITUTION:A pin 4, the diameter of which gradually diminishes towards the tip and at the tip of which a recessed part 5 is formed, is formed on the top force of a molding tool. The recessed part 5 has a constricted part 6 in the middle. A gently conically projected part 8 is formed on a bottom force 7 at the position corresponding to the pin 4. Accordingly, urethane resin enters the recessed part 5 of the pin 4 at molding, and the resin in the recessed part 5 and flash, which is developed between the pin and the bottom force, are removed as they adhere to the pin 4, by pulling out the pin 4 together with the top force. After that, air 10 flows through a hole 3, strikes against the projected part 8 of the bottom force, flows along the slope of the projected part 8 and enters the boundary part of a urethane sheet pad and the bottom force, resulting in allowing the urethane sheet pad to be bloated.

Title: Device for driving objective lens
Inventor: MORIMOTO SHINJI
IPC: G02B26/10
Filed: 1985-02-07
Abstract: PURPOSE:To avoid completely the influence of impact in the tracking direction even when an objective lens drive device acts by coupling two mobile parts with a flat spring and constituting such that the center of gravity of an entire mobile part is located in the center of the axis of a base. CONSTITUTION:The 1st movable part between a lens 1 and a lens holder 2 and the 2nd mobile part 3 capable of moving only in the tracking direction by means of an axis 5 are coupled with the flat spring 4, and the center of gravity of the entire mobile part G is located on the axis 5 of the base 13. Magnetic circuits 9a and 9c adjust drive forces F1 and F2 caused by a coil 12 not so as to apply undue force to the flat spring 4, and the impact in the tracking direction Tr is caused not to affect the mobile part. A drive force F3 drives the center of gravity g1 of the 1st mobile part in a focusing direction F0, however, the turbulence of the mobile part will not occur, because the flat spring 4 is jointed to an extending line l from the center of gravity. Accordingly the impact in the direction vertical against the optical axis can be eliminated even while the objective lens drive device supported by a fixing part is acting.

Filed: 1989-01-31
Abstract: PURPOSE:To improve the processing efficiency of an executing part by writing a transfer processing instruction directly to an instruction register while the condition of the executing part is held and transferring the value of a buffer memory on a memory to a comparative register. CONSTITUTION:An I/O request control part 305 informs an executing part 100 that an I/O request is activated when one of coincidence signal lines 414-484 from a pulse generator 400 is made active ('1'). The executing part 100 writes an instruction code to execute the I/O request processing directly to an instruction register 108 while the states of a program counter 101, a PSW 102 and a general register 103 are maintained, the values of control words 291-298 on a memory 200 are referred to, and a processing configuration is discriminated. For example, when the coincidence signal line 414 is made into '1', one data on a buffer memory 270 is transferred to a comparative register 411 when the control word 291 is '1'. Thus, the processing efficiency of the executing part is high, and even when the pulse generator is made into multichannel, the processing efficiency of the executing part is not lowered.

Filed: 1983-02-14
Abstract: PURPOSE:To provide the titled mechanism capable of reducing consumption of electric power, wherein only magnetic attracting force is utilized when changing the direction of a hammer bank equipped with a printing head. CONSTITUTION:A movable coil 11 is fitted to one end of the hammer bank 8, while an iron piece 12 is fitted to the other end, and both the coil 11 and the iron piece 12 a placed in a magnetic fild of permanent magnets 14. A rightward movement of the hammer bank 8 is effected by a straight forward force generated when passing an electric current to the coil 11 and an attracting force exerted on the iron piece 12, while a leftward movement is effected by an attracting force exerted on the iron piece 12 (a force so exerted as to bring back the iron piece 12 into the magnetic field which force is generated when the iron piece 12 tends to move out of the magnetic field due to inertia). By these forces, the hammer bank 8 is braked, stopped and is again accelerated in the reverse direction, whereby a shuttle returning is effected.

Title: Control device for automatic transmission
Inventor: YOSHIMURA HIROSHI
IPC: F16H61/16
Filed: 1989-01-31
Abstract: PURPOSE:To improve unstability of a control following a study control by inhibiting study correction by a study correcting means, which corrects the selection characteristic so that the change characteristic of a speed change condition is placed in a predetermined condition, when a temperature of oil is decreased to not more than a predetermined value. CONSTITUTION:A control device for an automatic transmission A, in speed change time of a speed change gear mechanism B, switches by the action of a selecting means H the supply-discharge characteristic of operating fluid to a friction element C, that is, whether or not the fluid is supplied and discharged through an orifice F, changing the change characteristic of a speed change condition corresponding to the friction element C in the change speed of its engaging condition. A detecting means J detects this speed change condition, and so that its change characteristic is placed in a predetermined condition, the selection characteristic of the selecting means H is study-corrected by a study correcting means K correcting the automatic transmission A for its between- solid error or the like. Now when a temperature of oil, detected by a detecting means L, is in a low value not more than the predetermined value, study correction is inhibited by a study correction inhibiting means M. Thus preventing unstability of a control following an increase of viscosity of the operating fluid, a speed change shock can be avoided from its increase.

Filed: 1993-02-10
Abstract: PURPOSE:To enable high-speed coordinate detection processing by specifying an output voltage value at the time of not pushing down an analog touch panel at a certain potential out of an available input range by pull-down or pull-up resistors. CONSTITUTION:This device is provided with a Y axis analog touch panel 11 and an X axis analog touch panel 12, and voltage input terminals ANX and ANY corresponding to the X and Y coordinates of a control part 10 are pulled down by pull-down resistors 15 and 16. Therefore, when a pen is not pushed down, the potential of the ANY terminal becomes almost close to 0V and when the potential of the ANY terminal is in a prescribed range, pen DOWN can be judged. It is similar to the ANX terminal as well. When the respective potentials are in the prescribed range, a coordinate value is calculated from an A/D converted value. Thus, it is not necessary to perform pen DOWN detection before coordinate detection, not only a push-down detection circuit is unnecessitated but also processing speed is accelerated and high describing can be sufficiently followed up.
