Title: Voltage control circuit
Inventor: NAKAMURA TAKASHI
IPC: H02H11/00
Filed: 1981-06-01
Abstract: PURPOSE:To prevent the malfunction of a voltage control circuit, by controlling the allowable level especially the lower limit level of the power supply voltage and at the same time detecting the fault of the ambient temperature. CONSTITUTION:The power supply voltage V-X is applied to a diode 1, a coil 2 and across a thermistor 3. When the voltage V-X has a fluctuation outside the lower limit of the allowable level, the current flowing to the coil 2 from the diode 1 is lowered suddenly. The driving energization of a magnetic reply switch 4 is lowered down to an open region. Thus a switch 4 is turned off. When the ambient temperature is higher than the upper limit level, the value of the current flowing to the coil 2 is lowered by the positive characteristics of the thermistor 3. As a result, the switch 4 is turned off.

IPC: G03F7/16
Filed: 1987-04-06
Abstract: PURPOSE:To prevent a scattered photoresist from readhering to a semiconductor substrate by a method wherein a length of a gap between an eave at a tip part of a conical-shaped barrier at an upper cup and a plane face of the semiconductor substrate is set within a prescribed range. CONSTITUTION:A semiconductor substrate 1 which is held by a rotary chuck 8 is covered with a conical-shaped barrier 4; a lower part 4c of the barrier 4 is connected to a discharge hole 5; while an annular eave 4b is hung at the inside of a tip part of the barrier 4.

Title: Repeat controller
Inventor: OSONE MASANORI
IPC: G05B21/02
Filed: 1987-04-06
Abstract: PURPOSE:To prevent the titled device from being influenced by a deviation between the preceding period and the succeeding period by allowing the device to execute operation for adding values respectively equal to the initial and final values of a data string in a current period out of the prescribed data strings outputted from an adder respectively by the necessary number of stages. CONSTITUTION:A control variable and an objective value are inputted to a subtractor 1 to calculate a control deviation and the deviation is stored in memory array E(0)-E(499) by a sampler 2 every period of 2msec. Then, the contents of a memory array W(0)-W(499) calculated in the preceding period are added to the contents of the memory array E(0)-E(499) by an adder 3 in accordance with E(I)+W(I) Q(6+1), 0<=I<=499 and the added contents are stored in Q(6)-Q(505). In this case, the same value of the Q(6) is stored in the Q(0)-Q(5) and the same value of the Q(505) is stored in Q(506)-Q(511) (operation based upon a arithmetic unit 4). An LPF5 calculates its output W from the value of the Q. The calculated result is the current period W(I) and stored up to the preceding period. The W(I) does not include the control deviation of the preceding period or the succeeding period.

Abstract: PURPOSE:To suppress the generation of bird's beaks to the minimum, and moreover, to eliminate the crystal defect, which is caused due to a stress to generate at the time of oxidation, by a method wherein, before the field oxide film is formed, frame-shaped withstand oxidation thin films are formed outside of the nitride films, which are the masking materials and are formed on the element regions. CONSTITUTION:An Si substrate 1 is prepared and after a thermal oxide film 2 is formed thereon, a nitride film 3 is deposited. Then, after a polycrystalline Si film 4 is deposited, a diffusion of phosphorus is performed, a patterning of resists 5 is performed and the resists 5 are selectively left. An etching is performed on the polycrystalline Si film 4 using the resists 5 as masks, and moreover, the etching is performed on the nitride film 3 as well. After the resists 5 are removed, an oxide film 6 is formed and after the oxide film on the Si substrate 1 is removed by performing a wet etching, a nitride film 7 is deposited. When an etching is anisotropically performed on the nitride film 7, the thin frame-shaped nitride films 7 are formed on the sidewalls of the nitride films 3 under the overhangs. After that, when the oxide films 6 and the poly-Si films 4 are removed, nitride film-shaped films are obtained. Then, when an oxidation is performed using the nitride films as masks, a field oxide film 8 is formed, yet the oxide film 8 obtainable at this time is one, which does not stretch to the lateral directions so much and has a sufficiently thick film thickness.

Title: Signal processing unit and level conversion circuit
Inventor: UEDA MASAHIRO
IPC: H03K19/086
Filed: 1994-04-22
Abstract: PURPOSE:To process an ECL level high frequency signal by a signal processing unit operating at a CMOS level and to reduce the power consumption. CONSTITUTION:A pre-processing circuit 31 applies serial/parallel conversion to an intermediate signal M2 at a PECL level. The serial/parallel conversion at the PECL level processes a high frequency signal. A level conversion circuit 12 implements conversion between the ECL level and the PECL level having the same logic level and consumes less power than the conversion between the ECL level and the PECL level with different levels. Furthermore, since level conversion is applied not to a parallel signal but to a serial signal, it is consumes less power. After an intermediate signal M3 being a parallel signal is obtained, the conversion to a CMOS level is implemented by a level conversion circuit 13. Thus, an intermediate signal M4 has a CMOS level and its frequency is low.

Abstract: PURPOSE:To increase the yield and the production efficiency in a resist pattern fabrication process by forming a protective film for covering a photoresist layer on the substrate to perform projecting exposure and development. CONSTITUTION:The whole surface of the semiconductor wafer on which a thermal oxide film is formed is coated with nonvolak-group positive photoresist by spin coating to form a resist layer. As a polyvinyl alcohol solution is being dropped on the circumferential part, the wafer is rotatd to form an annular protective film on the resist layer followed by pattern transfer by a projection- type exposure device and development to achieve fabrication of the resist pattern. Consequently, adhesion of foreign matter to the exposure device does not occur at all and neither does the patterning failure. For the protective film, hydroxypropyl cellulose, polyvinyl pyrrolidone, copolymer of methyl vinyl ether and maleic anhydride and cyclized polyisoprene are preferable.

Filed: 1986-04-14
Abstract: PURPOSE:To allow subscribers in the same slave station to have a talk by intra-station switching without using any radio circuit by transmitting a charging signal over a control channel. CONSTITUTION:When a logic circuit 4 detects subscribers who talk over a speaking channel being subscriber terminals belonging to the same office, the subscriber number of an originating subscriber terminal is inserted into the subscriber number area of an up control channel and the talk between the detected subscriber terminals is allowed by intra-station switching without any intervention of a radio circuit. A key station which receives the up control channel detects the originating subscriber number in the subscriber number area and inserts the originating subscriber number and a charging signal into the subscriber number area and charging signal area of a down control channel. Consequently, the slave station sends out the specific charging data over the down control channel.
