Title: Manufacture of semiconductor device
Inventor: KINOSHITA KATSUYUKI
IPC: H01L29/73
Filed: 1980-02-07
Abstract: PURPOSE:To reduce deterioration of characteristic such as junction leak by a method wherein the level difference of Si used for mask-matching after formation of a well layer can be formed in a heat treatment process after injection of ion into the well layer. CONSTITUTION:A thermo-oxidized film 2 is formed on an N type Si semiconductor substrate 1 and further thereon a nitrified film 9 is formed. Next, by using a photoresist 3 as a mask, the film 8 located in a region where the P well layer is formed is removed. Then, by using the resist 3 and the film 9 as the mask, a boron ion is injected, through the intermediary of the film 2, into the region where the P well layer is formed. Next, after the resist 3 being removed, oxidization for intrusion of the P well layer and for formation of the level difference of Si for mask-matching applied ina subsequent process is performed simultaneously by application of heat treatment in an inactive fas containing oxygen. By forming the level difference of Si in this way without application of thermal oxidization for hours, deterioration of characteristic such as junction leak harmful for C-MOSIC can be reduced.

IPC: H01J9/227
Filed: 1982-02-03
Abstract: PURPOSE:To prevent the generation of defects on the internal surface of a panel so that an excellent phosphor surface may be obtained, by spreading aqueous sodium salt solution on the internal surface of the panel, at least, in either process out of the three, namely a photo-absorptive substance film forming process, a phosphor film forming process and a film forming process. CONSTITUTION:Aqueous solution of 0.15% sodium acetate is spread over the entire internal surface of a panel after purifying treament for the internal surface of the panel 1. Next, a black stripe 2 is formed by spreading, for instance, graphite as prescribed. Next, a phosphor film 3 is formed as prescribed by spreading a tricolor phosphor in regular order, then a bulb is formed through the prescribed process. In this way, a product is formed, and when defects are generated on the phosphor film 3, the bulb is disassembled into a panel and a funnel, and a phosphor film is over again formed on the internal surface of the panel. Thus, Moir e pattern has been never generated on this phosphor surface. In short, the concentration difference of sodium on the surface of the panel which has been hitherto generated is suppressed, so that the unevenness on the panel surface caused by hydrofluoric acid-washing is reduced and the Moir e pattern has never been generated.

Title: Electric shutter device
Inventor: MIZOGAMI KAZUNORI
IPC: G03B7/083
Filed: 1979-02-14
Abstract: PURPOSE: To achieve simpler construction and higher reliability by constituting a trigger switch with a transmission gate switch.  
     CONSTITUTION: The transmission gate switch T constituted by a P-channel MOSFET and an N-channel MOSFET is connected between a reference voltage circuit VREF and an operation amplifier OP1. Then, when a shutter release button is  pushed and the front curtain travels, the trigger signal supplied to the trigger signal  input terminal Tm becomes L level and is inverted by an inverter IN to turn OFF  the transmission gate switch T. This causes the charges having been accumulated  to be discharged by reverse bias from a photo diode SPO according to the quantity  of received light. The charges are compared with a decision voltage in the operational amplifier 2 and when they become lower than the decision voltage, an electromagnet MG is de-energized and the rear curtain travels.

In such a manner, voltage across opposite ends of the resistance R8 is monitored and measured as a pulse current. Resistance R3 is connected also between a collector of the bias current detection circuit 24 and an LD 28 to monitor voltage across the opposite ends of the resistor R3 and measure a bias current. Hereby, both pulse current and bias current are monitored and detected highly accurately.

Abstract: PURPOSE:To reduce the effect of noise by allowing a standard/non-standard detection circuit to extract a synchronizing signal and a color burst signal from a luminance signal and a chrominance signal from a comb-line filter so as to discriminate the standard/non-standard input signal. CONSTITUTION:A comb-line filter 102 separates an inputted composite video signal into a luminance signal and a chrominance carrier signal and a color demodulation circuit 106 demodulates the chrominance carrier signal into a color difference signal, which is outputted.

Furthermore, a burst lock PLL 119 extracts a color burst signal from the video signal inputted from a terminal 101 and generates and outputs a synchronized burst lock clock. Then a standard/non-standard detection circuit 121 based on them decides whether or not the inputted video signal satisfies the NTSC system and decides it to be the standard signal when satisfied and it to be the non-standard signal when not satisfied.
