IPC: B29L31/34
Filed: 1991-04-26
Abstract: PURPOSE:To coat a photoresist simply and in a short time by a method wherein, in a low-pressure atmosphere, a filmlike photoresist is placed on the main surface of a semiconductor wafer in which uneven parts have been formed on the surface, the atmosphere is then returned to normal atmosphere and the photoresist is pasted. CONSTITUTION:A filmlike photoresist 3 is placed on the main surface of a semiconductor wafer in which a second layer 2 provided with uneven parts has been formed on a first layer 1. When the filmlike photoresist is placed on the semiconductor wafer in which the uneven parts have been formed, it is essential that is placed in a low-pressure atmosphere. When the photoresist is placed in the low-pressure atmosphere, air reservoirs 4 which have been produced between the second layer 2 and the filmlike photoresist 3 are crushed due to a pressure difference when the atmosphere is later returned to normal atmosphere; the photoresist 3 is brought into close contact with the surface of the second layer 2. When the filmlike photoresist is placed in a low-pressure state and the atmosphere is later returned to normal atmosphere, the photoresist can be pasted on many semiconductor wafers at a time, and the wafers can be treated in large quantities.

Title: Phase locked oscillation circuit
Inventor: MAKINO SHINYA
IPC: H03L7/14
Filed: 1987-05-20
Abstract: PURPOSE:To prevent the phase of an output clock signal from being fluctuated even if missing of pulse exists in an input clock signal by applying self-running to a voltage controlled crystal oscillator succeedingly in the control state just before the occurrence of missing of pulse at the detection of missing of pulse. CONSTITUTION:A missing pulse detection circuit 10 detects missing of pulse in an input clock signal A and a gate signal generating circuit 11 receiving a detection signal E generates a gate signal F after the missing of pulse is finished and a period of a prescribed bit or over in the output clock signal B elapses. A charge pump circuit 12A is kept to a high impedance state to bring the voltage controlled crystal oscillator 16 into the self-running state, and the phase of the output clock signal B obtained by applying frequency- division 17 to the oscillation output for a period where missing of pulse is consecutive is kept to the phase before the missing of pulse takes place. Thus, even if missing of pulse takes place in the input clock signal, the stable output clock signal without phase fluctuation is outputted succeedingly.

Title: Contactless switch
Inventor: SATO KATSURA
IPC: H03K17/78
Filed: 1988-05-20
Abstract: PURPOSE:To limit the ON time of a semiconductor element in accordance with a load current and to prevent the breakage of a contactless switch by comparing the overload signal with the sawtooth wave signal superposed on an input signal and controlling a photocoupler. CONSTITUTION:When the DC signals S are supplied to the terminals 1a and 1b, the signals S are superposed on the sawtooth wave signal Sn produced by a sawtooth wave signal generating circuit 12 and the output of a comparator 13 is set at 'H'. A photocoupler 3 is turned on by an 'H' signal and a triac 7 is triggered. Thus a current I flows to a load 11. The secondary side voltage of a transformer 16 is rectified and smoothed and the voltage ES is applied to one terminal of the comparator 13. The voltage of an overload detecting circuit 14 rises up to Eh from ES when the current I exceeds a rated level. Thus the output Eo of the comparator 13 is set at 'H' only when Sn>Eh is satisfied and triggers the triac 7. The load current I is controlled by the voltage Eh since this Eh is proportional to the current I. Then the current flowing to a contactless switch is automatically controlled. As a result, the thermal breakage of said switch due to the overcurrent of a semiconductor element can be avoided.
