Title: Piezoelectric oscillator using composite vibrator
Inventor: HIRAMA KOICHI
IPC: H03B5/32
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To obtain a highly stable quartz oscillator which uses no thermostatic chamber by connecting a specific number of piezoelectric vibrators having radial frequency temperature characteristics in parallel and setting the peak temperature and peak frequency of the vibrators flat. SOLUTION: This oscillator consists of a parallel connection of four LC series circuits and a parallel connection of the parallel capacity C01 +C02 +C03 +C04 of four BT-cut crystal vibrators, an amplifier load capacity CL, and a load resistance -RL. The crystal vibrators #1 and #4 have mutually equal equivalent inductance L and peak frequency fT and their peak temperatures are set to t1 and t2 respectively. Further, vibrators #2 and #3 have mutually equal equivalent inductance KL and peak frequency fT2 and their peak temperatures are set to t2 and t3 . At this time, the peak temperatures of the vibrators #2 and #3 are arranged symmetrically at points a half of the temperature difference between the temperatures t2 and t3 away from the midpoint between the peak temperatures t1 and t4 of the vibrators #1 and #4.  Consequently, the highly stable oscillator is constituted which has about 10-8 at 5 to 45 deg.C.

Title: Method for preventing inhomogeneous distribution of developer
Inventor: MATSUOKA MAKOTO
IPC: G03G15/08
Filed: 1988-11-30
Abstract: PURPOSE:To obtain uniform development concentration by rotating an agitator when a process cartridge is replaced. CONSTITUTION:When an upper main body 1b is closed, the agitator 13 incorporated in a developer storage part is rotated for a specific period. Namely, even if a developer is located one-sidedly at the time of the replacement of the process cartridge, the one-sided presence of the developer 15 is uniformed by rotating the agitator at the time of the replacement of the process cartridge and the distribution is uniformed to eliminate the one-sided presence of the developer 15. Thus, the developer is distributed automatically and uniformly at the time of the replacement of the processor to eliminate the one-sided presence of the developer and an irregularity in the development concentration is also eliminated to obtain the uniform development density.

Filed: 1986-12-19
Abstract: PURPOSE:To obtain an electromagnetic actuator capable of working with small coil magnetomotive force by providing a coil exciting a self-maintaining magnetic circuit and a movable iron core becoming a parallel magnetic path to the attraction part of a movable plunger for magnetization of a permanent magnet and the coil. CONSTITUTION:When a current is conducted for a moment to a coil 25 in the direction generating magnetization in the same direction with the magnetization of a permanent magnet 16, a movable plunger 18 is is attracted stronger and maintained while a movable iron core 22 is also attracted and maintained up to the position abutting against the stepped parts 20 and 21 while overcoming the reaction force of a spring 27. When the excitation of the coil 25 is released in said condition, magnetic flux of the permanent magnet 16 is shunted to a circuit passing through the attraction part 19 of the movable plunger 18 and to a circuit passing through the movable iron core 22. Consequently, attracting and maintaining force reduces so as to work in a repelling condition by the force of a spring 26. In order to make the movable plunger 18 actuate in a repelling direction, it is sufficient enough to have coil excitation to the extent of reinforcing the magnetization of the permanent magnet so that a small coil current as compared with the case, where excitation is performed in the reverse direction as practiced in the conventional method can be sufficed well.

Filed: 1987-11-30
Abstract: PURPOSE:To eliminate the danger of the overheating of a bomb main body by melting a plug and discharging the gas corresponding to the temperature of a heating place suitably when the abnormal overheating of the place, which has the danger of heating, is detected with the discharging of the gas from a gas bomb. CONSTITUTION:A discharging port 10 of a gas bomb 9, in which the gas is filled, is sealed by a plug 11 composed of a low melting point alloy and a heating wire 8 is arranged near the discharging port 10. When an abnormal overheating occurs at detecting object places 1 and 2 of the abnormal overheating and the temperature arrives at the operating temperature, for example, 150 deg.C of a heat sensitizing element 5, the heating wire 8 is heated by a battery 7, a plug 11 is melted by the heat and internal gas is discharged from the discharging port 10 of the gas bomb. By detecting the gas with a gas detector 12, it is detected that the abnormal overheating occurs. Thus, since the heating wire 8 conducted at the time of the overheating is provided at the discharging port 10, it is not necessary to heat the bomb main body excessively, and since the internal pressure is increased and thus, the generation of a dangerous condition can be evaded.

Title: Alternating current linear servomotor
Inventor: MIZUNO TSUTOMU
IPC: H02K41/03
Filed: 1989-11-27
Abstract: PURPOSE:To facilitate positioning control by lessening a gap between the permanent magnet of a stator and the armature of a needle and enhancing the thrust or braking force at the tine of acceleration or emergency stop and enlarging the gap and reducing the thrust ripple and the detention force at the time of positioning. CONSTITUTION:A piezoelectric actuator 19 consisting of laminated piezoelectric materials such as ceramic expands and contracts depending on increase and decrease in the applied voltage. That is, when the voltage applied to the piezoelectric actuator 19 is increased a gap (g) between an armature 15 and a permanent magnet 9 enlarges and when the voltage is lowered the gap (g) lessens. Therefore, when a motor is accelerated or stopped in an emergency, the voltage applied to the piezoelectric actuator 19 is lowered to lessen the gap and, at the time of positioning, the voltage is increased to enlarge the gap. Thereby the acceleration time and braking time can be shortened and positioning control can be facilitated.

Next, after giving a binder in the blended mat, it is made into a sheet-shaped substance with high density through compression. As binders, it is preferred to employ resin such as epoxy resin, unsaturate polyester resin and PVA resin, and it is preferable that the adhesive rate is in the range of 0.1 - 20wt%. In the next place, the blended sheet substance obtained herein is superimposed and laminated with the thermoplastic sheet substance and then they are heated and pressed at the temperature of softening and melting temperature or higher of the thermoplastic resin.

Abstract: PURPOSE:To enter an operation state without any trouble even when memory contents are destroyed by providing an operating voltage detecting circuit, a hold voltage detecting circuit, and a trigger circuit which generates a trigger signal, and checking data in a memory with the trigger signal when respective modes are changed. CONSTITUTION:A microcomputer 1 controls the whole telephone set and also judges whether or not a commercial power source is higher than an operating voltage and whether or not the voltage of a back-up battery 8 is higher than a memory hold voltage through two detecting circuits 11 and 12.
