Title: Electron beam device
Inventor: OKUMURA MASAHIDE
IPC: H01J37/22
Filed: 1988-04-15
Abstract: PURPOSE:To easily search the visual field by modulating the intensity of a CRT with one or both of the generated rectangular signal and the information signal when the magnitude of the information signal generated from a sample exceeds the preset level. CONSTITUTION:The secondary electrons generated when an electron beam 3 is radiated to a sample 2 are detected by a detector 25 and amplified by an amplifier 26 to the preset level into the intensity modulation signal of a CRT 29. When a switch 31 is set to the S2 side and the voltage of a comparison power source 34 is adjusted, the portion at the end of a sample holder on the screen of the CRT 29 where an image or the like has been seen is illuminated with the uniform brightness, the voltage of the comparison power source 34 is fixed at this time. A sample bed is moved, when the brightly illuminated portion is observed on the CRT screen, the sample bed is stopped there, the switch 31 is again set to the S1 side, the magnifying factor is adjusted, and the portion can be observed with the desired magnifying factor. The visual field can be easily searched.

Title: Carriage lock mechanism of magnetic disk device
Inventor: TAKIZAWA TOSHIMITSU
IPC: G11B21/02
Filed: 1991-03-29
Abstract: PURPOSE:To improve the lock torque in the lock area in no operation time and to surely lock the device by rapidly increasing the shortest distance from a magnetic member in accordance with separation of the carriage of a magnetic attracting type carriage lock mechanism from the specified position. CONSTITUTION:In the state that the carriage 25 stops at the lock position in no operation time, the distance between the attracted member 32 and a projecting part 29a is narrowed and also the confronting area of both is increased, hence improving the lock torque to surely lock the carriage 25. On the other hand, when the carriage 25 separates from the lock position in the operation time, the variation rate between the member 32 for a rotary angle of the carriage 25 and the projecting part 29a is increased and the lock torque can be damped quickly. Thus the offset torque at the seek area is suppressed and the control at the seek time is made easily.

Title: Ignition control device for internal combustion engine
Inventor: MIYATA SHIGETOSHI
IPC: F02P5/155
Filed: 1990-04-09
Abstract: PURPOSE:To keep the primary current of a primary coil constant, and thereby enhance control accuracy in ignition regardless of environmental temperature by connecting a fixed resistor to a thermister in parallel, in which the resistor is disposed in an environmental field identical to that of the thermister. CONSTITUTION:Since a fixed resistor 21 is connected to a thermister 10 in parallel, the resistance value of the thermister 10 is decreased as an environment is increased in temperature, meanwhile, the resistance value of the fixed resistor 21 is measured, the combined resistance value of the thermister 10 and the fixed resistor 21 is changed at a decrement rate smaller than that of the single thermister 10 even if the environment is high in temperature. This thereby enables the apparent constant of the thermister 10 to be made smaller than that of former ones by means of the fixed resistor 21 even if the constant of the thermister 10 is actually restricted. Accordingly, primary current can be made roughly constant regardless of change in environmental temperature. In the range of low environmental temperature in particular, the resistance value of the fixed resistor 21 exerts great influence thereon, primary current can thereby be made constant.

Title: Take-up mechanism for thermal transfer printer
Inventor: OSUMI MAKOTO
IPC: B41J2/325
Filed: 1985-04-30
Abstract: PURPOSE:To make it possible to smoothly perform the taking-up of a thermal transfer ink sheet even if a taken-up amount becomes much, by providing a means for detecting the diameter of the thermal ink sheet or the number of rotations of a take-up roll and a means for stepwise changing take-up torque or the number of rotations when the diameter of the take-up roll reaches a definite amount or more or the number of rotations reach a definite amount or less. CONSTITUTION:When the diameter of a thermal ink sheet 5 becomes large as the taking-up thereof advances, the thermal ink sheet 5 is contacted with the actuator 28 of a detection means 26 and, when the actuator 28 is contacted with a base part 27 after the taking-up is further advanced, the supply of a current to a solenoid operation device 20a is stopped and an armature 21 is separated from a gear 17. The gear 17 races and a gear 18 is connected to a drive shaft 19 to transmit torque of rotation. Because (r) and (d) become large as the take-up diameter of the thermal ink sheet becomes larger, the number (n) of rotations of the take-up shaft 13 become small and the tension (f) of the thermal ink sheet also becomes small. Because the torque of rotation is large even if tension becomes small, the separation of the thermal ink sheet 5 and image forming paper is not damaged and can be smoothly separated.

Abstract: PROBLEM TO BE SOLVED: To obtain a high single crystal yield by controlling heat flows in the side direction and in the bottom direction of the single crystal of a compound semiconductor toward a heat flow in the top direction of the single crystal in the growth process of the single crystal of a compound semiconductor. SOLUTION: In this method for storing a compound semiconductor in a quartz ampule 1 and heating the compound semiconductor to produce a single crystal of a compound semiconductor in a boat 2 for growing a single crystal, since the exchange of heat in the crystal growth is controlled by radiation and an opaque part 4 is formed from the bottom of the quartz ampule 1 to the sides of the boat 2 for growing a single crystal, scattering occurs in heat radiation to the crystal side and the crystal bottom, heat radiation transmitting the quartz ampule 1 is reduced to control heat flows toward the crystal side and the crystal bottom. Heat is efficiently released to the crystal top by a transparent part 3 formed at the upper part of the quart ampule 1 so that a heat flow toward the crystal top is more dominant that those toward the crystal side and the crystal bottom.  Consequently a preferable solid-liquid interface is formed to raise a single crystal yield.
