Abstract: PURPOSE: To reduce the occurrence of defective dimension works by reducing the through-feed speed of works when a machine is started again after a dressing, calibrating dimensions sufficiently and normalizing the adaptation of the grinding wheel surface, stability of each part and the operation of the machine.  
     CONSTITUTION: When an operation restarting instruction signal 21 is ordered replacing a dressing starting signal 20, a gate 32 opens and a regulating wheel driving motor 11 starts running at a low speed set by a setting device 33. At the same time, a timer 22 starts and when the set time is up, gates 28 and 30 open, the motor 11 is accelerated by an accelerating or decelerating time constant generating circuit 29 along the CD line and changes to a steady opertion DE set by a steady speed setting device 27. During A'CD, works are through-fed by the regulating wheel at low speeds, dimension calibration is performed sufficiently and adaptation of the grinding wheel surface, stabilizing of each part of the machine and normalization of operation are performed.

Abstract: PURPOSE:To enhance the good product ratio of a lead shaping operation by installing the following: a lower former which shapes a lead between itself and an upper former; and a lead guide which holds the lead which has been shaped. CONSTITUTION:The following are installed: a movable unit 5 which is composed of a lead retainer 2, a cutter upper blade 3, an upper former 4 and a work retainer 9; a lower former 6; a cutter lower blade 7; and a lead guide 8. When a taping component 1 is fed, the movable unit 5 is lowered. A lead for the taping component 1 is first centered by the tip part of the upper former 4. Then, in a state that the twist of the component has been corrected by using the work retainer 9, the lead is fixed by using the lead retainer 2, and the lead is cut by using the cutter upper blade 3. In addition, the lead is shaped along the flat face of the lower former 6 from an R-face at the upper former 4, and it is held by using the lead guide 8. That is to say, since the lead is shaped and cut simultaneously, the good product ratio of the lead can be enhanced.

Title: Device and method for switching keyboard
Inventor: KAWADA TAKEAKI
IPC: G06F3/02
Filed: 1999-01-18
Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for switching keyboard with which the external keyboard of a computer is switched, without operating a virtual keyboard on a display part when the external keyboard is connected/ disconnected. SOLUTION: When a keyboard connection/disconnection detecting circuit 14 detects that an external keyboard 10 is disconnected from a main body, it is reported to an arithmetic circuit 16. Corresponding to this notice, the arithmetic circuit 16 displays a virtual keyboard on one part of the screen of a display device 20 and starts the control of the virtual keyboard on the screen by a pointing device 18. When it is detected the external keyboard 10 is connected, the arithmetic circuit 16 erases the virtual keyboard from the screen and starts using the external keyboard 10. Thus, an operator can provide similar operability, without being conscious of the presence/absence of the external keyboard 10 (without changing the setting of OS or application software).

Title: Memory block securing/releasing device
Inventor: HIROSE TOSHIO
IPC: G06F12/02
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To secure a memory block without retrieving the required number of idle memory blocks and to speed up the security of the memory block by retrieving the using frequency of free memory blocks in an allocation unit management table and securing a memory block from a frequently used allocation unit. SOLUTION: A free memory managing means 13 retrieves the most frequently used entry out of unused allocation units and sets pointer 21. When a using frequency counting means 14 adds '1' to the using frequency of the allocation unit, a using frequency changing means 15 is started at a fixed period and resets the using frequency of all entries in an allocation unit management table 22 by a value obtained by subtracting current using frequency from a fixed value. Since an allocation unit having small using frequency is changed to a leading allocation unit in the table 22 by the resetting operation a memory pool 23 can be uniformely utilized and the security speed of a memory block can be accelerated.

IPC: H01L21/336
Filed: 1986-01-20
Abstract: PURPOSE:To reduce the irregularity of a Vth even in an SOI in which crystal grain boundaries exist by performing the gate oxidation of an MOSFET at 1,100 deg.C or lower by an HCl oxidizing method to form oxide films of substantially the same thickness even for silicon layers of different azimuths. CONSTITUTION:The gate oxidation of an MOSFET is executed at 1,100 deg.C or lower by an HCl oxidizing method. In other words, oxidizing temperatures are altered to oxidize silicon wafers of planar azimuths (100) and (111). An abscissa axis of a graph indicates the oxidizing temperature, and an ordinate axis indicates the difference of the thicknesses between the oxide film of the (111) plane standardized from the oxide film thickness of (100) plane and the oxide film of the (100) plane. The difference is 45% in case of wet oxidizing method at 900 deg.C, but the difference is reduced to approx. 33% in case of the HCl oxidizing method, and when the oxidizing temperature is further raised, the thickness gradually decreases, and the thickness is reduced at 1,150 deg.C to 5%.

Title: Power transmission
Inventor: NAKAMURA HIDEAKI
IPC: F16H63/34
Filed: 1992-01-23
Abstract: PURPOSE:To certainly block the torque transmission from a output portion and improve transmission efficiency by providing a mechanism to lock the rotation of an output portion and also a mechanism to release the lock of a planetary gear mechanism having its two sections made an input portion and an output portion respectively. CONSTITUTION:When, for instance, clockwise rotating torque is input in an input shaft 5, a planetary gear 2 makes a rotation centering a shaft 6 and transmits counterclockwise rotating torque to an annular gear 3 because respective rotary drums 4, 10 have their clockwise rotation locked by means of a coil spring 23b. An outer ring 12 then enlarges the diameter of the coil spring 23b and simultaneously as the coil spring 23b locks the rotation of the annular gear 3, it releases the lock of a rotation drum 4. This results in transmitting the torque of the input shaft 5 to the output shaft 8 of the rotation drum 4 through the revolution of the planetary gear 2. On the other hand, when, for instance, clockwise rotation torque is input into the output shaft 8, the torque is not transmitted any more because the coil spring 23b locks the rotation of the rotation drum 4.
