Title: Liquid crystal display
Inventor: OKAZAKI NETSUO
IPC: G02F1/137
Filed: 1982-01-13
Abstract: PURPOSE:To reduce visual angle dependability of transmittivity in case when voltage is applied, so that uniform display can be executed even if it is seen from any direction, by setting rise directions of a liquid crystal molecule in case when voltage is applied, of a TN type double layer GH cell, to anti-parallel to each other. CONSTITUTION:Liquid crystal layers 21, 22 are oriented in the direction as  indicated with an arrow, and rise directions 201, 202 of a liquid crystal molecule in case when voltage is applied are made anti-parallel to each other. Also, visual angle dependence of the first layer and the second layer is negated and  averaged, therefore, visual angle dependence of transmittivity becomes small,  and becomes almost constant as to the whole circumference. The liquid crystal molecule and a dichroic dystuff molecule in the liquid crystals 21, 22 are capable of modulating 2 polarizations making a right angle to each other, by each  layer, because the orienting direction on the surface of the opposed substrate is  formed so as to make a right angle, in each layer, and the orienting direction  on the boundary surface of both the layers is set to a right angle.

Abstract: PROBLEM TO BE SOLVED: To surely detect a position even for a position detection mark with an extremely small amount of recess and projection change (level difference). SOLUTION: A member for limiting the luminous flux of illumination where a plurality of light transmission parts 32A-32J and 33A-33I are formed symmetrically to a light axis is arranged on a lighting system pupil surface (Fourier transform surface for a position detection mark) and a member for limiting the luminous flux for image-forming where a region which is conjugate with the light transmission parts 32A-32J and 33A-33I and a region including the periphery is light-screening parts 34A-34J and 35A-35I is arranged on an image- forming system pupil surface.  0-order diffraction light out of diffraction light due to the position detection mark of illumination light from, for example, one light transmission part 32E is screened by a corresponding light-screening part 34E and other diffraction beams 35A-36C and 37A-37D are transmitted and utilized as luminous flux for image-forming, thus effectively utilizing only the diffraction light and forming the image of the position detection mark.

Title: Method for drawing and annealing copper or copper alloy
Inventor: MATSUMOTO HARUO
IPC: C22F1/00
Filed: 1988-01-13
Abstract: PURPOSE:To prevent deposition at the time of annealing and also to prevent discoloration after drawing or annealing by carrying out drawing and annealing under the application of silicone oil or silicone oil and light oil. CONSTITUTION:At the time of drawing and annealing copper or a copper alloy, silicone oil or mixed oil of silicone oil and light oil is applied as a lubricating oil at the time of drawing, or, this oil or mixed oil is applied prior to annealing after drawing. By this method, the occurrence of deposition in the course of annealing is eliminated and productivity is improved. Moreover, since the film of silicone oil remains even after annealing, no discoloration occurs even if this copper or copper alloy is allowed to stand in the air for a long period.

Title: Method for measuring mean staying time of visitor
Inventor: NOSAKA TOSHIYUKI
IPC: G07C9/00
Filed: 1994-01-19
Abstract: PURPOSE:To improve arithmetic precision when the mean staying time of visitors is calculated based on the entry time and exiting time of the visitors. CONSTITUTION:A store entry sensor 1 outputs a detection signal when detecting a visitor entering the store and a store exiting sensor 2 outputs a detection signal when detecting a visitor exiting from the store. A store entry memory 11 cumulates the entry elapsed time from the measurement start time (service start time) of the visitor to the entry time. A store exiting memory 12 cumulates the exiting elapsed time from the measurement start time of exiting persons up to the current point to the exiting time. A store entry counter 13 counts entering visitors and a store exiting counter 14 counts exiting visitors. A main arithmetic circuit 8 adds the cumulative exiting elapsed time from the store exiting memory 11 and the value obtained by multiplying the numeral, obtained by subtracting the measurement start time from the current time, by the number of staying visitors at the present point of time, and subtracts the cumulative entry elapsed time from the store entry memory 11, and then divides the arithmetic value by the number of entering visitors to find the mean staying time.

Abstract: PURPOSE:To remove echo signals by controlling the switch on the input side with the AND output signal between the output of a variable threshold controlling circuit which detects the trailing edge of an input signal and the output generated during the period the out circuit of a multifrequency signal receiver is in operation. CONSTITUTION:Since a multifrequency signal inputted into terminal IN includes echo signals between gaps of digit signals, these echo signals are inputted into variable threshold controlling circuit 30 through switch 33, amplifier 1 and band elasing filter 2. Circuit 30 compares the maximum value of the input signal with the output of the rectifier which generates variable threshold signal whose value is lower than the maximum value and, when the variable threshold is higher, circuit 30 detects the trailing edge of input signal and enters it into AND gate 31. The output generated during the period the out circuit which actuates after confirming that the input signal is effective is operating is inputted into gate 31 and the output of the gate 31 is entered into delay switching circuit 32. Circuit 32 outputs signals only the period echo signals are continued to be outputted to control switch 33 by opening the switch so as to remove echo signals equivalently.

When similarly, as to remaining areas 3, 4, they are expanded till they are made coincident with the ruled line part 5 subject to thinning processing and the screen processing is applied and the result is synthesized. Thus, a defect such as the production of blank between areas or between an area and a ruled line part, or an excess of overlap of two kinds of tint patterns at the border and the production of high density line is avoided.

IPC: H03K17/04
Filed: 1980-01-18
Abstract: PURPOSE:To make it possible to change over the voltage quickly, by switching through using a high speed pulse generator which contains a pulse transformer and a switching element. CONSTITUTION:When transistor TR2 is in off condition, the voltage of power source 1 is almost impressed on load 3. Then a pulse voltage is impressed through pulse transformer 7 in the direction which contradicts the voltage impressed on load 3 and, at the same time, a voltage is impressed on TR2 through driving circuit 6 so that TR2 will turn on. By this, the voltage of load 3 is contradicted quickly by the pulse voltage impressed from transformer 7 having a quick built-up. Then TR2 is turned on at the time when the pulse voltage from transformer 7 is almost dimin ished, and both ends of load 3 are shorted. By this, the voltage can be changed over quickly by switching through using a high speed pulse generator containing a pulse transformer and a switching element.
