Title: Servo control system for stepping motor of floppy disc drive
Inventor: CHIYOU SEIKAN
IPC: G11B5/265
Filed: 1988-12-08
Abstract: PURPOSE: To facilitate servo control of a stepping motor without recording a separate burst signal on a data track by comparing the level of prescribed signals each read out through an erasing head and thereby moving the head from a prescribed center line of the track to the inside or the outside of a disket. CONSTITUTION: With a ferrite core separated of two erasing heads, and with the erasing heads provided with a data reading function each by winding a coil, an FDD is allowed to read out data only at the time of a seek operation, so that a signal is detected from the erasing head at the time of track seek. In other words, detected signals are compared, with the head moved from the center of the track or in the direction toward the outside, so that the head is confirmed to be positioned in the center of the track at the point where the waveform of these detected signals are both at the '0' level (seek completion point); therefore, the track servo control is made possible of the stepping motor without recording separate burst signals on the data track.

Title: Fixed-focus camera
Inventor: KOIKE KAZUMI
IPC: G03C3/00
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To provide a fixed-focus camera capable of compensating the focal position of a photographing lens made of resin with a simple constitution. SOLUTION: A pin 31 provided in the photographing lens 20 made of resin projects from a cam hole 34 formed to be inclined to a lens holder 25 and a lens presser 26, and is put between a leaf spring 39 and an optical path length compensator 38 where a hysteresis loop is drawn in a temperature area different from the temperature range of the use circumstances of the camera and which consists of shape memory alloy. When ambient temperature rises, the compensator 38 is flexibly deformed and presses the pin 31 toward an end 34a side. Thus, the lens 20 is turned along the cam hole 34 and extended to a subject side, and the focal position of the lens 20 is compensated on a film surface. The displacement amount Q of the compensator 38 gets small with the fall of the ambient temperature, and the pin 31 is pressed back to an end 34b side by the spring 39.  Thus, the lens 20 is moved to the film surface side, and the focal position of the lens 20 is compensated on the film surface.

Title: Gas discharge tube lighting system
Inventor: ODA ISAMU
IPC: H05B41/282
Filed: 1987-12-11
Abstract: PURPOSE:To make it possible to automatically start a Townsend discharge and to control the amount of ultraviolet rays after lighting by applying a composite wave form of a dc voltage and a pulse voltage to a gap between the anode and cathode of a gas discharge tube. CONSTITUTION:Ionizing a gas sealed in a discharge tube by means of a dc voltage applied to the gap between the anode and cathode, and limiting the value of the dc voltage to the lowest necessary for sustaining charged particles produced by ionization, the charged particles remaining in the tube after the application of the dc voltage are continuously excited by pulsed voltages. A breakdown occurs at the time of build-up by this excitation and a current flows through the discharge tube. As a result, a shift of energy lever of the charged particles occurs, and ultraviolet rays are emitted to cause a phosphor to emit light. Combining the application times of the dc voltage and pulsed voltage in this way, the discharge can be automatically started and the amount of ultraviolet rays can be controlled.

Title: Toner particle for color
Inventor: NOGUCHI KOJI
IPC: G03G9/09
Filed: 1986-12-24
Abstract: PURPOSE:To obtain high reproducibility of color toner and sharp and beautiful projected images even by an OHP by forming a transparent coating layer consisting of a chromatic coloring agent on the surface of toner particles consisting of a transparent resin. CONSTITUTION:The transparent coating layer consisting of the chromatic coloring agent is formed on the surface of the toner particles consisting of the substantially transparent resin. Such resin is exemplified by an acrylic resin. The color tone is insufficient if the content of the chromatic coloring agent forming the coating layer is below 1wt.% of the toner particles. The chromatic coloring agent liberated from the surface of the toner particles is exposed and induces scumming if the content exceeds 10wt.%. Such cases are, therefore, undesirable. The chromatic coloring agent to form the coating layer may be not only the coloring agent of single color but also a mixture or combination of plural kinds of colors. The reproduction of the color toner is thereby extremely facilitated and even if the original picture image is projected by the OHP (overhead projector), the color toner thereof is surely reproduced.
