Title: Automatic focusing system
Inventor: EGUCHI MITSUO
IPC: H04N5/232
Filed: 1981-04-13
Abstract: PURPOSE:To obtain a focused state of high accuracy with relatively simple constitution by detecting the peak position of the correlations of the intensity distributions of an object by the luminous fluxes past the different parts of a photograhic optical system. CONSTITUTION:The luminous fluxes past the two pints A, B of a photographic lens system are condensed to the two regions on the CCD placed in the positions conjugate with a film. The outputs of a CCD16 goes through an LPF24, an amplifier 25, and a binary coder 26, and the intensity distribution signal D of the object is outputted time-serially from a shift register 27. The signals thereof are equally divided to the data DA, DB for the luminous fluxes A, B by a multiplexer, and are sent to a correlerator 50 via a selector and a shift register. The output current thereof is converted to voltage by an I-V converter 51, and this voltage goes through a sample holding circuit 52, and is compared with the peak value of the circuit 52 in a peak detector 53. When it exceeds the peak value, a gate 54 opens, and the correlation position data are outputted from a counter 55, whereby focusing is accomplished. Thereby, the focused state of high accuracy is obtained with the relatively simple constitution.

Abstract: PURPOSE:To enable an epitaxial film to be deposited in high selectivity by a method wherein a sheet plasma region is formed between a plasma beam source and a counter electrode, silicon-containing gas is led in a reaction chamber and then a semiconductor substrate is impressed with specified voltage. CONSTITUTION:A wide sheet plasma region 18 in high density is formed between a plasma beam source 10 and a counter electrode 12 by the action of a magnetic field formed of a multitude of focussing coils 26, a permanent magnet for the counter electrode 12 arranged on rear side of the electrode 12 and another permanent magnet 44 arranged on the outlet of the plasma beam source 10. Next, a semiconductor substrate 16 with a silicon oxide film patterned thereon is mounted on a specimen electrode 14 in a reaction chamber 22. When silicon- containing gas is led in the reaction chamber 22, the silicon-containing gas ionizes in the plasma region 18 to collide with the semiconductor substrate 16 on the specimen electrode 14 impressed with negative voltage to the counter electrode 12 so that an epitaxial film may be deposited on the surface of the semiconductor substrate 16. Through these procedures, the epitaxially deposited film can be selectively formed.

Title: Seat attaching portion rendering seat tiltable fowardly
Inventor: EMIRIO AMUBAZU
IPC: A47C1/032
Filed: 1978-05-09
Abstract: The seat of a chair is mounted on a post or other supporting member by a seat mount which permits the seat to tilt forward (front end down) to a forward and downward rake of about 41/2 DEG . A bracket connected to the seat and located under generally the center of the seat pivots on an axle that is received and supported by a mounting plate rigidly fastened to the supporting member. Springs compressed between the mounting plate and the bracket restrain the seat from tilting down, and co-engageable stop surfaces associated with the bracket and mounting plate limit the extent of tilting of the seat (both forward and backward rake, when the latter is provided for). By joining the mounting plate and bracket by parallel front and rear axles fixed to the bracket and arranged to disengage axle-engaging surfaces on the plate, or vice versa, the seat can tilt both forward and backward; in this mode, the seat pivots or rocks on one axle, and the other axle disengages the axle-engaging surface. An optional movable blocking element can be included to disable the rearward tilt mode when desired.

Filed: 1990-03-06
Abstract: PURPOSE:To produce the above head by injection molding to an arbitrary shape with high accuracy by using plastic as the materials of 1st and 2nd sliders which clamp an electromagnetic converting element from both sides. CONSTITUTION:This magnetic head is constituted by adhering the plastic sliders A2 and B3 molded by an injection molding technique to both sides of the electromagnetic converting element 1 thereby clamping the element. A polyphenylene sulfide resin and polyimide resin are used in order to prevent the deterioration in the sliding and wear characteristics of the magnetic head and a recording medium. Since the sliders 2, 3 are made of the plastic in such a manner, the injection molding technique is usable and the mass production of the head to the arbitrary shapes with the good accuracy is possible. The production cost of the magnetic head is thus reduced.
