Abstract: PURPOSE:To stably feed stacked sheets irrespective of the amount by making a sheet stacking member touched or detouched with a specified angle with respect to a feed roller by means of a spring. CONSTITUTION:A middle plate 2 is arranged in a cassette frame 1, which plate 2 is fitted in a fitting part 3a, of a link member 3 by means of both end pins 2a so as to be able to turn freely, which link member 3 is also fitted to a pin 4a of the frame 1. The middle plate 2 is supported to move freely in the vertical direction while maintaining horizontal conditions with respect to the frame 1 by means of the link member 3. A pressing spring 5 is provided on the under surface of the middle plate 2, and the center of a feeding roller 6, the fitting part 3a1, and the pressing spring 5 are aligned on the same vertical line. Accordingly, the sheet loaded on the cassette frame 1, regardless of the loaded amount, can be stably fed only changing the rotated angle of the link member 3, by the movement of the middle plate 2 to abut onto the feeding roller 6 in the vertical direction maintaining horizontal condition.

Title: Electrophotographic sensitive body
Inventor: YOKOYAMA MASAAKI
IPC: G03G5/05
Filed: 1989-10-31
Abstract: PURPOSE:To enhance stability of a photosensitive body at the time of repeating electric charging-exposure operations and to suppress rises of surface potential and residual potential by incorporating a high molecular weight polycyclic hindered phenol in organic polysilane. CONSTITUTION:For example, a charge generating layer 2 is formed on a conductive substrate 1, and on this layer 2 is formed a charge transfer layer 3 made of the organic polysilane composition as a charge transfer material containing the high molecular weight polycyclic hindered phenol. When the photosensitive material containing the polysilane as the charge transfer material undergoes repeated charging-exposure operations, both of surface potential and residual potential rise considerably. The addition of the phenol permits it to react preferentially with a component deteriorating the surface, thus preventing deterioration of the polysilane itself, suppressing rise of the surface potential and residual potential at the time of repeating charging-exposure operations, and stabilizing electrophotographic characteristics for a long period.

IPC: H02M7/48
Filed: 1994-10-21
Abstract: PURPOSE: To obtain a DC-AC inverter whose output voltage can be changed without changing the value of the input voltage with an adjustable back-light. CONSTITUTION: A DC voltage source 3 composed of a diode D1 and capacitor C3 is connected to one end (on a transistor Q2 side) of a feedback winding Nf for oscillating transistors Q1 and Q2. The diode D1 is connected to the capacitor C3 in a direction in which such a voltage that can reversely biases the transistors Q1 and Q2 can be obtained. A serial circuit of a variable resistor R2 and a resistor R3 is connected as a variable impedance circuit between the connecting point of the voltage source 3 with the capacitor 3 and diode D1 and the other end (transistor Q1 side) of the winding Nf. Therefore, a highly reliable small-sized high-efficiency DC-AC converter can be obtained at a low cost, because no DC-DC converter is required for changing the value of the input voltage.

IPC: B30B9/32
Filed: 1990-10-22
Abstract: PURPOSE:To prevent a can treating device from damage and to improve the efficiency by discriminating the weight of the can and avoiding a press load exceeding a prescribed, value. CONSTITUTION:When a can exceeding a prescribed weight is inserted, a spring 14 shrinks, a stopper 8 rotates and a lever 81 shuts the light of a photocell 15 to send a signal to a controller 12. A can which is judged to be too large in weight is inserted by the actuation of a release part 9 into a defectives recovering box 62. A step 102 discriminates whether it is a metal or not and decides whether it can be pressed or not. A movable press base 3 is divided into a member 29 transmitting the drive of a motor 5 and a member 26 abutting on the can 4 and performs press working and an elastic member 30 is clamped and pressed. Consequently, when a spray can containing combustible gas, a comparatively light and incompressible lump, etc., for example, are guided and pressed between a press base 2 and a movable press 3, the elastic member 30 exceeding a prescribed force is surely safe.

Title: Fiber-optic-sagnac interferometer for measuring rotational speed
Inventor: PEETAA GURORUMAN
IPC: G01C19/72
Filed: 1991-10-30
Abstract: PURPOSE: To further improve a fiber optic gyro which is lowered in the carrier frequency of a read signal by proper modulation or keying of a light source. CONSTITUTION: The light from the light source 1 crosses a first directional coupler 2 and a polariscope 3, and a 2nd directional coupler splits it into two partial light beams, which pass through a fiber coil 5 in mutually opposite directions. A phase modulator 6 fitted preferably to one end of the fiber coil imposes additional phase modulation on both the partial light beams. The phase modulator 6 is operated with a driving signal 8, which extends to general time- dependent phase modulation imposed on an interferometer array. As a result of a Sagnac phase generated by the modulation and an inertia rotating speed, the read signal is obtained by an optical detector 7 connected to the directional coupler 2 on a read channel 9. A current making the light source 1 operate is supplied through a line 10.
