Title: Auto-focusing system
Inventor: YANAI TOSHIAKI
IPC: G01N21/94
Filed: 1987-03-02
Abstract: PURPOSE:To stably perform the focusing control between an observation optical system and a wafer surface with a high precision by detecting the out-of-focus state in accordance with a contrast ratio of two variable density stripe patterns projected on the wafer surface. CONSTITUTION:A projection optical system 30 fixed to an observation optical system 16 which observes a wafer surface 12, two variable density patterns 22 and 24 projected on the wafer surface by the projection optical system 30, a two-dimensional image sensor 32 which picks up images of parts of the wafer surface where variable density patterns are projected, and a focusing control means 35 are provided. This means 35 takes the output signal of the two-dimensional image sensor 32 as the input to obtain an average contrast ratio of two variable density stripe patterns projected to the wafer surface and controls a driving means, which relatively moves the wafer and the observation optical system 16, so that the contrast ratio is about one. Since dark and light parts of two variable density stripe patterns are arranged on the wafer surface with a width longer than that of a circuit pattern in a direction inclined to the direction of the circuit pattern, the focusing control between the wafer surface and the observation optical system is stably performed with a high precision.

CONSTITUTION:A multiplexer 104 is controlled by a control signal F3 of the same signal as a basic clock, a control signal F3 selects an I signal C3 at a 'H' level, when the inverting signal of the control signal F3 is the 'H' level, selects a Q signal C2, and during the image period of an input chrominance signal C0, a chrominance signal C1 is supplied through a multiplexer 105 to a multiplier 106 at every half period of the basic clock. Consequently, during the image period, a Q signal C2 and an I signal C3 are inputted as a multiplicand to a multiplier 106 and the second matrix coefficients RQ2'-BI2' are inputted as a multiplier respectively. The color difference signal obtained in such a way is equal to the signal using a smoothing circuit conventionally.

Abstract: PROBLEM TO BE SOLVED: To enhance room temperature rising characteristics of a heater and to ensure comfortableness of gentle heating depending on the number of tatami mats by providing a switch for previously switching the heating capacity depending on the number of tatami mats. SOLUTION: When the room temperature is lower than a specified level, the maximum combustion quantity is switched to a level higher, by a specified amount, than a maximum combustion quantity set by a switch 8 depending on the number of tatami mats.

Abstract: PURPOSE:To realize favorable heat sealing by a method wherein the titled film consists of random copolymer of propylene and ethylene, the content of ethylene ingredient of which is 0.5-7.0wt%, shows a specified endothermic peak. CONSTITUTION:The titled film consists of random copolymer of propylene and ethylene, the content of ethylene ingredient of which is 0.5-7.0% by weight, and shows an intrinsic endothermic peak P0 and, in addition, another high temperature peak P2 on the temperature side higher than the endothermic peak in a differential scanning calorimetrical analysis. the existence of the high temperature peak P2 in a curve, which indicates the results of measurements of heat absorption in an orthogonal co-ordinates with temperature as the abscissa and with heat absorption as the ordinate, means that the titled film has the same crystal structure as that representing itself as the intrinsic peak P0 and, in addition, another crystal structure having a melting point higher than that of said crystal structure. The above-mentioned composite crystal structure widens the temperature range from the start to the finish of melting of the film during heating, resulting in enabling to realize favorable heat sealing.

Filed: 1983-03-22
Abstract: PURPOSE:To prevent unnecessary operation during photography by providing a detecting means which detects whether a film pack is loaded or not to a film photographing device which has an instant photographic film feeder. CONSTITUTION:The output of a built-in battery is detected through openings 1a and 1b in the back cover of the film pack. This battery voltage is applied across resistances R1 and R2 to turn on and off a transistor (TR) T1 through a resistance R3. A signal 6 is at LOW when the film pack is loaded or at HIGH when not according to the ON-OFF operation of the TRT1. The battery decision level varies with the value of the R1 and this level is set properly to decide on not only whether the film pack is loaded or not, but also whether a old film pack is loaded or not. Thus, this device prevents unnecessary operation and misoperation in instant photography.

Abstract: PURPOSE:To produce the glass capsule in which superfine particles are confined without flocculation of the superfine particles between each other by heating a raw material for the superfine particles to evaporate in an inert gas and heating a glass raw material to evaporate in the presence of such superfine particles. CONSTITUTION:A raw material target 4 which is the raw material of the superfine particles is placed in an evaporation chamber 1 and is irradiated with a laser beam through a window 5 to heat the raw material to evaporate. The superfine particles are formed when the evaporated raw material is rapidly cooled by the inert gas from an introducing pipe 6.

The pressure in the evaporation chamber 1 is highest, the pressure in the reaction chamber 2 is lower than this pressure and the pressure in a capturing chamber 3 is further lower and, therefore, the products are introduced into this capturing chamber 3. Then, the desired glass capsule superfine particles are stuck on a quartz substrate 11 in the capturing chamber 3.
