Filed: 1989-05-22
Abstract: PURPOSE:To prevent temporary temperature decrease of specimens during transferring between each of the fixed hot plates, by providing movable hot plates moving so as to synchronize the specimens while keeping a specified gap dust above the specimens. CONSTITUTION:Movable hot plates 8, 9 are heated at, e.g. the temperature equal to that of fixed hot plates 2-4. A conveying apparatus 10 is provided, and the. hot plates 8, 9 move so as to synchronize the movement of specimens during transferring between each of the fixed hot plates 2-4, while keeping a constant gap just above the specimens. For example, if the movable hot plates 8, 9 are larger or equal to the specimens, the plates can shield wholly the specimens 5 from cold air shower 7 blown against from above, and can heat wholly the specimens 5 from the above, while the specimens 5 are transferred between each of the fixed hot plates. Thereby temporary temperature decrease of the specimens during transferring between each of the fixed hot plates 2-4 can be prevented, so that the following are surely achieved; the increase of adhesion between a substrate and resist, the stabilization of resist sensitivity during photolithography process, and the permeation prevention of developer into a pattern at the time of development.

Title: Original reader
Inventor: NAGASAWA KIYOTO
IPC: H04N1/04
Filed: 1987-05-26
Abstract: PURPOSE:To reduce the influence of dust or a flaw, by providing a shading correction data fetch mode and an ordinary read mode, and changing a read picture element size in a sub scan direction between those modes. CONSTITUTION:An original oscillation output OSC is inputted to a frequency divider 21, and is frequency-divided to 1/256, on one side, and is changed to a picture clock VCLK by a signal FSHD representing a shading mode. Since the FSHD is set at a low level in a normal mode, the OSC is selected as it is as the VCLK. And since the FSHD goes to a high level in the shading mode, a pulse in which the OSC is frequency-divided to 1/256 can be obtained as the VCLK, and a shift pulse SH is also provided with a cycle of 256 times the cycle in the normal mode. Therefore, a picture element size W goes to a size of 256 times the size in the normal mode. Thus, since a large size of the read picture element size W can be selected in the shading mode, the influence of the dust or the flaw scattered sporadically can he reduced.

Abstract: PROBLEM TO BE SOLVED: To estimate deterioration of a dry seal part and to predict in advance the trip timing of a compressor and effect a planned stop, in the method for managing soundness of the dry gas seal part of a compressor. SOLUTION: Gas is fed to a dry gas seal part 100 of a compressor 80 through a gas inlet 54 for seal and flows out from an outlet 55 and is guided to a flare. Detecting signals from a flow meter 65 and a pressure gauge 40 are inputted to a computing device 43 via A/D converters 41 and 42. Data on a primary gas leakage amount or a pressure previously obtained from past operation is accumulated at a memory device 44, an approximation curve to a compressor trip time is established from the data by the computing device 43 and stored at the memory device 44. A time, starting from a present point of time and ending to the time when trip occurs is predicted, and further a plurality of leak amounts or pressures at an arbitrary time are measured. From the measurements, a curve during operation is also predicted and two types of data are compared with each other.  When a predicted curve during operation is drastically different from an approximation curve, it is previously decided in advance that abnormality of gas seal will occurred.

Filed: 1982-07-20
Abstract: PURPOSE:To offer the semiconductor device excluded with conduction noise, avalanche noise and moreover, easy to manufacture by a method wherein the device is constructed of semiconductor pellets of the plural sheets having P-N junctions and to perform high-frequency action and laminated between a pair of electrodes arranging the rectifying directions thereof, and a high resistor consisting of a semiconductor interposed between the electrodes adjoining to the cathode side thereof. CONSTITUTION:Depletion layers are formed though a little in P-N junctions of the respective silicon pellets 4a-4n to make junction capacitances to exist, and when a voltage is applied, and junction capacitances are charged to reach conduction, a time constant expressed by the product of junction capacitance and resistance is enlarged because of interposition of the high resistor 6, and forward recovery time is elongated. Accordingly, the current rise rate di/dt at forward recovery time is reduced, a counter electromotive voltage is reduced, and conduction noise is not generated. Moreover, when a reversely directional voltage is applied, the avalanches are generated locally in the silicon pellets 4a-4n on the anode side because of ununiformity of the alloted voltage rate, and even when pulse noise is generated, because the peak value thereof is limited by the high resistor 6, it is not transmitted to a Braun tube as avalanche noise.

Title: Data processor
Inventor: DEGUCHI MASASHI
IPC: G06F12/08
Filed: 1987-05-25
Abstract: PURPOSE:To reduce the disturbance of a pipeline in a pipeline processing by inhibiting the access of a cache memory when an operand access attribute is written. CONSTITUTION:An operand fetch controller 13 changes the access control of a cache memory 11 and an address conversion buffer 12 by an operand access attribute. Thus the processing speed is increased in a pipeline process where the memory 11 and the buffer 12 are used. The memory 11 includes an associative part 200 and a data part 201 and gives an access to the part 200 when a writing operation is carried out with an operand fetching action to update a logical address. Thus the cache updating performed by an advance instruction is limited to the part 201 only. As a result, the same control is possible as a case where a physical address is stored in the part 200.

IPC: H04N9/45
Filed: 1980-09-11
Abstract: PURPOSE: To suitably cope with a frequency shift or a color burst, by constituting the frequency variable range of a voltage control type oscillator smaller than the repeated frequency of the color burst in a PLL type color synchronizing circuit.  
     CONSTITUTION: A chrominance subcarrier output of a voltage controlled type oscillator 5 is provided to a phase comparator 9 through a tinting circuit 6 and a phase shifter 7. The comparator 9 compares phase of the color burst extracted by a burst gate 8 and the chrominance subcarrier, and provides its output to the oscillator 5 through an LPF 10. Also, a sweeping circuit 11 outputs a stepping sweep voltage wave-form to the oscillator 5. By this circuit configuration, a frequency variable range Δf of the oscillator 5 is set so as to be ΔfH against the repeated frequency fH  of the color burst. In this way, even in case of the oscillator 5 using an LiTa vibrator, a malfunction of a color synchronizing circuit by an adjacent frequency component is not caused. Also, when an output of the comparator 9 is made to pass  through the LPF 10, the frequency lead-in range is narrowed, and the noise resisting characteristic in a weak electric field is improved.
