Abstract: PURPOSE:To suppress not only the noise but also vibration of a pulse motor by supporting the pulse motor on a support frame through an elastic buffer body and supporting the end part of the motor shaft having a pulley mounted thereto by the shaft support part integrally constituted along with the support frame through a bearing. CONSTITUTION:A ball bearing 24 is fixed to the shaft support part 23 integrally constituted along with a support frame 13 and formed by bending a part of the support frame 13 and the end part of a motor shaft 16A is supported by the ball bearing 24. The constitution mounting a carriage motor (pulse motor) 6 to the support frame 13 through a rubber damper 14 is the same as a conventional example but, herein, by pref. using rubber having hardness (JIS A-scale) of 40-60 deg. as the rubber 14A of the rubber damper 14, noise reducing effect can be enhanced still more. The shaft support member having the shape matched with that of the shaft support part 23 may be formed as a separate body to be fixed to the support frame 13.

Title: Powder extinguisher and its preparation
Inventor: TAKAHASHI HIROYUKI
IPC: A62D1/00
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To enable accurately reaching to a combusting object without being fanned by a flame wind of a fire caused by pelletizing a fire extinguishing material finely granulated. SOLUTION: Each composition of fire extinguishing agent is crushed singly or in a mixed state to be granulated and a fire extinguishing material obtained is pelletized. Even when the force of a fire of a combusting object is very large, the fire extinguishing agent discharged can reach an object to be extinguished accurately and in a short time without being fanned by the force of the fire. This eliminates an excess of the fire extinguishing agents more than a prescribed quantity while realizing an initial extinguishing in a short time, especially further enhancing the fire extinguishing efficiency in the fire of wood or oil.

Title: Driver for disk contained in cartridge
Inventor: NISHITANI TADASHI
IPC: G11B17/043
Filed: 1990-02-07
Abstract: PURPOSE:To prevent a large force from being delivered to a shutter even when the shutter is in contact with a drive shaft by adopting a shape of an end of a guide slot of a receiving frame to be a slot expanded in the loading direction of a cartridge so as not to disturb the movement of an operating pin. CONSTITUTION:An end of an operating pin guide slot 6a of a cartridge receiving frame 6 is devised to be a slot expanded so as not to disturb the movement of an operating pin 8a in the loading direction of a cartridge 1. Thus, even when the operating pin 8a is depressed at a front face of a projection ridge of a shutter 2, no large force is exerted to the operating pin 8a. Then a rising position lock member 13 is turned while being depressed by the cartridge 1 and moved by a spring force of a slide frame 11 to descend the cartridge receiving frame 6 and even when the shutter 2 is in contact with a drive shaft 7a, since the cartridge loading port is supported by a lower support cam 11b and the loading depth is supported by a vertical clip cam 11c, the cartridge receiving frame 6 is tilted to jump up the cartridge loading port. Thus, no large force is exerted even when the shutter is in contact with a drive shaft and a damage to the drive shaft or the shutter is precluded.

Abstract: PURPOSE:To achieve high-speed control over the extent of a phase shift by reducing insertion loss by varying the gains of the 1st and 2nd gate input signals by gate biases by using a dual gate FET, and weighting and synthesizing them. CONSTITUTION:After an input signal is branched into two, the phase of one branched signal is shifted by 90 deg. through a pi/2 phase shifter 8, amplitude and polarity switching are performed by balanced modulators consisting of elements 7, 9 and 10, and 7', 9' and 10', and two sequence of signals are synthesized at a part 11 with a 90 deg. phase difference. Through the operation of the former modulator, the input signal to the branching circuit 7 is branched into two, and one signal is shifted in phase by 180 deg. through a pi phase shifter 9 and inputted to the 1st and 2nd gates of a dual gate FET10 to weight and synthesize two 180 deg. out-of-phase signals. The FET has gains to both the gate inputs and those gains are adjusted by bias voltages of both the gates, so the 1st and 2nd gate bias voltages VG1 and VG2 are controlled to weight and synthesize the input signal. The latter modulator has the same constitution.

Abstract: PURPOSE:To improve the accuracy in reading interference fringes by having a light source, optical elements which divide the luminous flux reflected on a surface to be inspected to the luminous fluxes having the optical paths in the two directions; clockwise and counterclockwise. CONSTITUTION:An interferometer has a light source 21 which emits polarized light, polarizing prisms 22, 26 which are so selected as to permit transmission of the polarized light emitted from the light source 21, quarter-wave plates 23, 25, etc. The luminous flux emitted from the light source 21 passes the prism 22 then the quarter-wave plate 23 by which the luminous light is converted to circularly polarized light and is made incident to the prism 22. Since the polarization direction is rotated 90 deg. in this stage, the luminous flux goes toward the plate 25, and passes the same, by which the luminous flux is converted to circularly polarized light. Said light is divided to the two luminous fluxes which are clockwise and counterclockwise and intersect orthogonally with each other by the prism 26. The accuracy in reading the interference fringes is improved by the above-mentioned constitution.

IPC: G01D7/00
Filed: 1983-02-23
Abstract: PURPOSE:To display simultaneously plural segments on one scale by providing a means for shifting the origin of a scale display. CONSTITUTION:When a scale key is operated after inputting the numeric data by operating the numeric key in a key input part 20, the numeric data is applied via an X register 23 and a display register 30 to a scale display part 7. The 1st segment of the length assigned by the numeric key is displayed with 0 as an origin on the part 7. When the numeric key and a right shift key are operated, the zero point shifts toward the right by as much as the numerical value assigned by the numeric key to the origin position with respect to the 2nd segment. When the scale key is operated after operating the numeric key in succession, the segment of the length assigned by the numeric key from the origin position shifted to the right is displayed as the 2nd segment. The plural segments are thus simultaneously displayed on one scale.
