Abstract: PURPOSE:To reduce the number of shift registers, to simplify a drive circuit and to reduce cost by a method wherein an output of each bit in a shift register is connected to a plurality of gate elements and one of the gate elements is selected in accordance with an external signal. CONSTITUTION:For example, a drive circuit 20a drives sixty four heating resistors. A circuit 20 comprises shift registers SR1-SR32 and AND gate elements G1-G64. Output terminals of the AND gate elements are connected to output pad H1-H64 via corresponding switching transistors. The pad H1-H64 are connected to corresponding heating resistors respectively. Thus, each output of the shift register is connected to a plurality of gate elements and one of the gate elements is selected in accordance with an external selection signal. As a result, a plurality of heating resistors can be driven by means of one shift register. Thereby, it is possible to reduce the number of the shift registers and to markedly simplify the driving circuit without generating wasteful time of printing.

Title: Method for forming optical element and apparatus therefor
Inventor: KAWAMURA EIJI
IPC: C03B11/00
Filed: 1989-11-17
Abstract: PURPOSE:To improver transferability by conveying a glass material to a heating furnace, heating and softening the glass material in the furnace, then conveying the softened glass material between forming forces and press forming the glass material. CONSTITUTION:A previously ground and polished glass material 7 is placed on a conveying tool 11, which is then conveyed just under an opening of a heating furnace 3 with a conveying pallet 12, inserted into the central part of the heating furnace 3 with a heating ejector pin 6 and heated with a heater 5 for a prescribed time. The resultant heated and softened glass material 7 is subsequently conveyed through the conveying tool 11 into a space between the cylindrical top and bottom forming forces 9 and 10 with a conveying arm 8 and press formed. Since asymmetric deformation is not caused in the glass material 7, symmetric and homogenous pressure acts on the glass material 7. Furthermore, the glass material 7 is cooled from the outer peripheral part to the central part due to the cylindrical form of the top and bottom forming forces 9 and 10. Since temperature distribution is not produced in the circumferential direction, an optical element without any astigmatism is obtained.

Title: Ashing process
Inventor: ICHIHASHI HIROCHIKA
IPC: H01L21/302
Filed: 1986-12-16
Abstract: PURPOSE:To improve the ashing rate by a method wherein a resist film is subjected to a microwave ashing process using O2 gas mixed with CF4 and N2 gas. CONSTITUTION:A resist film on wafer surface is ashing-processed with microwaves using O2 gas mixed with CF4 and N2 gas. For example, the ashing rate of O2:CF4:N2=10:X:1 of mixed reactive gas is around two times higher than that of O2:CF4=10:X:1 without adding N2 of mixed reactive gas thus increasing the ashing rate to improve the throughput. Furthermore, when Al film is patterned using a resist as a mask, Cl2 gas can be completely removed by increasing the ashing rate to reduce the Al corrosion markedly. Thus, an Al wiring can be provided with high reliability.

Filed: 1989-11-20
Abstract: PURPOSE:To thin a device and to load a cassette by providing a clamper moving with a tray on the tray and excluding the spring means of the clamper from above the tray in a tray ejected state. CONSTITUTION:The clamper 6 is held in a position where a spring means is installed at the inner side of a front panel 11 and a drop-voltage is removed in the ejected state of the tray 4. When cassette loading starts, only the tray 4 horizontally moves and the clamper 6 voltage-drops the cassette on the tray.

IPC: B60K31/04
Filed: 1992-11-11
Abstract: PURPOSE:To secure a travel feeling so smoothly even in time of going into a flat road or a downward slope from upward slope during constant speed controlling by performing such control as selecting from deceleration to acceleration and vice versa at an amplified output or as suspending the amplification of the decelerating control in synchronization with the count end of a timer otherwise. CONSTITUTION:An changeover to decelerating control takes place at an adjustable speed control transfer point T1 yet more lower than a usual transfer point T0. In addition, since this decelerating control is carried out by an amplified output, a transistor Tr10 of a bent valve switching part 10 of an actuator 5 is turned to ON at longer time than that of the usual one. As a throttle valve 4 is operated to return at a shorter time than that at the usual one, a plus deviation (overshoot) between actual car speed and memory car speed to be produced at a point of time when entering from an upward slope to a flat road can be checked to the minimum.

Title: Drying method for interior of hollow body
Inventor: SUZUKI KAZUMI
IPC: F26B3/00
Filed: 1991-11-18
Abstract: PURPOSE:To reduce the volume of a blower to a low value and shorten a drying time by a method wherein an insertion body in a shape similar to that of a hollow body is arranged in the hollow body and gas for drying is caused to flow through a gap between the hollow body and the insertion body. CONSTITUTION:A balloon 4 previously folded and expanded in a shape similar to that of a sample 1 when the balloon is filled with air is inserted through an inlet nozzle 2 in the sample 1, such as a hollow tank. Air heated by a heater 13 is fed as air for drying through a vent hole 5 to a gap between the sample 1 and the balloon 4 by means of a regulating valve 7. The air for drying fed to a gap between the sample 1 and the balloon 4 flows through the gap between the sample 1 and the balloon 4 approximately in parallel to the inner wall surface of the sample 1 and is discharged through an outlet nozzle. This method causes the flow of gas for drying through a flow passage having a low sectional area and reduces an air flow at which a given vaporizing speed is provided.
