Inventor: KAWASAKI KIKUO
IPC: G03G15/00
Filed: 1978-11-06
Abstract: PURPOSE: To simplify the constitution and detect securely and at high sensitivity, by detecting presence or absence of copying paper by means of signal detector used commonly by LEDs which light up sequentially through program control and corresponding photo detectors.  
     CONSTITUTION: LED1, 1A... disposed in specified plural positions in the copying route, being connected to amplifier circuits 4, 4A... structured in Darlington connection of transistors, light up pulses sequentially through a minicomputer which controls the copying machine. Photo transistors 2, 2A... corresponding to LED1, 1A... detect the reflected lights of pulse lights from LED1, 1A... through the copying paper, and presence or absence of copying paper is detected according to the lighting of LED1, 1A... by a common comparator 6 in which the reference value is set. Therefore, in a simple constitution using a common comparator circuit, presence or absence of copying paper may be detected securely and at high sensitivity by intermittent light emission by large current due to pulses.

Title: Impact printer head
Inventor: TORISAWA AKIRA
IPC: B41J2/28
Filed: 1986-06-13
Abstract: PURPOSE:To enable a high-speed recording, by a construction wherein longitudinal effect type piezoelectric elements are disposed so as to allow armatures to move in a recording direction. CONSTITUTION:In a non-printing condition, armatures 4 are depressed to be in contact with longitudinal effect type piezoelectric elements 9 due to the rebounding force of springs 10. In this condition, according to a recording command, for example, the voltage of the longitudinal effect type piezoelectric elements is simultaneously applied to both coils 1, whereby cores 3 attract plungers 2 along with the extension of the longitudinal effect type piezoelectric elements 9, then the armatures 4 displace leftward in the figure due to the synergistic effect. As a result, wires 6 move forward and conduct a recording action. Since the conduction to the coils 1 and the longitudinal effect type piezoelectric elements 9 is cut after the wires 6 have completed the recording action, the wires 6 return to its original condition due to the resilience from the platen side and the rebound of the springs 10, and the armatures 4 are depressed against the longitudinal effect type piezoelectric elements 9. After that, the same action is repeated for recording.

Title: Setting method for cutting conditions of cutter and equipment therefor
Inventor: NAGAHIRO MASAJI
IPC: B23D55/00
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To efficiently establish cutting conditions by automatically reproducing once adjusted optimum cutting conditions. SOLUTION: In cutting a work by relatively keeping a saw blade housing 5 having a band saw towards and away from the work W by means of a fluid pressure cylinder 41, the flow rate and pressure of a working fluid for working the fluid pressure cylinder are adjusted by means of a flow control valve and a pressure regulating valve to establish cutting conditions. In rotating a cutting speed adjusting dial 67 for working the flow control valve by a worker to adjust the cutting speed of a cutting tool, a speed adjusting clutch 75 for transmitting the rotation of a speed adjusting motor 73 to the cutting speed adjusting dial 67 is turned off to previously store the rotating position of the cutting speed adjusting dial as setting data on a memory 95.  In interrupting an automatic operation, the speed adjusting clutch 75 is turned on to rotate the cutting speed adjusting dial by means of a cutting speed adjusting dial rotating device. Thus, the rotating position is automatically set to the rotating position based on the setting date previously stored on the memory 95.

Title: Polarizing element
Inventor: ITO YOSHITAKA
IPC: G02F1/139
Filed: 1989-05-30
Abstract: PURPOSE:To improve the efficiency of conversion to light polarized in one direction to make a polarizing element compact and low-cost by constituting the element of a means, which condenses only one of two linearly polarized components whose planes of polarization are orthogonal to each other, and a polarization plane rotating means where twisted nematic liquid crystal to rotate the plane of polarization at 90 deg. is arranged. CONSTITUTION:Ordinary ray components of light 101 made incident on the polarizing element go straightly as shown by an arrow 104 without refraction on the boundary surface between a double reflection layer 102 and an isotropic layer 103, but extraordinary ray components are refracted in accordance with the change of the refractive index on the boundary surface and are spatially collected and are focused on TN type liquid crystal elements 107 and 108 which give a phase difference. Since the direction of polarization of extraordinary ray components is rotated at 90 deg. when they are transmitted through the liquid crystal element part 107 to which an electric field is applied, this direction of polarization is equalized to that of ordinary ray components. Consequently, incident rays are scarcely absorbed, and exit light 110 whose direction of polarization is satisfactorily equalized is obtained. Thus, the compact and inexpensive polarizing element is obtained which efficiently converts light to light polarized in one direction.
