Title: Photo interrupter
Inventor: ANDO TETSUYA
IPC: H01L31/12
Filed: 1987-03-05
Abstract: PURPOSE:To expand the setting distance between light emitting and light receiving elements by connecting a circuit driving the light emitting element by a pulse current, and a circuit connecting a peak hold or a pulse width conversion type amplifier to the light receiving element in parallel, thereby increasing the sensitivity. CONSTITUTION:A capacitor C of a proper capacitance C is connected in parallel with the light emitting element 1 and a pulse driving circuit A. The mean value of the driving current flowing to the element 1 is decreased by the pulse current driving and the light emitting current is set remarkably larger at an instantaneous value. Since the photodetection current is also a pulse current, a differentiation circuit is provided to the emitter of the light receiving element 2 and the peak hold or pulse width conversion type current amplifier B is connected in series, the output is formed to be of integration type, thereby increasing the change in the total current I0. In the total current I0=I1+I2, since the relation of I1=current I'1 of element 1, input current I'2 of amplifier B>>current I''2 of element 2, the result of I0=I'1+I'2 is obtained and because of I'1<<I'2, the relation of I0 I'2 is obtained, and the rate of change is very excellent. Thus, a proper photo interrupter is obtained.

Abstract: PURPOSE:To improve uniformity and stability of a temperature by providing a cavity resonator incorporating an egg type plasma lamp at a first focus of an elliptical mirror and formed of a radio wave shielding plate at the side end of the first focus, and a high frequency oscillator. CONSTITUTION:A microwave power of high frequency is applied from a high frequency oscillator 7 to a cup-like cavity resonator 5 formed at its end of an elliptical mirror l of a radio wave shielding plate 4 through a waveguide 6 and a rotary fitting 15.

The light is reflected on the inner surface of the mirror 1 and condensed to a sample 8 of a second focus. Thus, the sample is highly heated to be melted. When the sample 8 is lifted while being slowly rotated, a crystal is grown. Since the lamp 2 can correct distribution of light at the second focus to uniformly condense it due to the egg shape of a light source, the entire periphery of the sample can be uniformly heated, and its high speed rotation is not required.

Title: Gas feeding nozzle for radical reaction type precision processing apparatus and manufacture of gas feeding nozzle
Inventor: NAGAOKA HITOSHI
IPC: H01L21/301
Filed: 1993-03-12
Abstract: PURPOSE:To feed a reactive gas into the bottom of a deep channel by a method wherein a pair of nozzle half bodies wherein gas flow recessed parts are subjected to an etching process on the inner side of a jointed periphery so as to leave a lot of jointing projections, are integrally jointed by forming a gas flow path and a gas ejection opening between the pair of the gas flow recessed parts by the facing gas flow recessed parts. CONSTITUTION:Nozzle half bodies 1c and 2c is formed by etching-processing gas flow recessed parts 1c and 2c where a lot of jointing projections 1e and 2e are scattered. The nozzle half bodies 1 and 2 are faced each other and pressure transmitting tools 8 with the approximately same thermal expansion coefficient as those of the bodies are brought into contact with the outer faces and the nozzle half bodies l and 2 are pressed by means of bolts 9 to perform diffusion jointing and thereby to prepare a gas feeding nozzle with a gas flow path T communicating with gas inlets 1b and 2b and a gas ejecting opening. As a result, there is no possibility to expand significantly the nozzle outerward caused by the pressure of the reactive gas. Therefore, even when the cut channel becomes deep, the outer face of the nozzle is prevented from being brought into contact with the wall face of the cut channel to be able to feed smoothly the reactive gas into the bottom of the deep channel.
