Title: Vibration-proof rubber and manufacture thereof
Inventor: TAKANO KAZUYA
IPC: B60G7/02
Filed: 1991-10-31
Abstract: PURPOSE:To provide a vibration-proof rubber having almost linear spring property while securing its durability performance, and provide a method of manufacturing the vibration-proof rubber easily. CONSTITUTION:A vibrationproof rubber is composed in such a way that a rubber resilient body 3 of a throughhole 4 gets in contact partly to close most of the throughhole under no load, and that the throughhole opens when a predetermined load or more is applied. The rubber resilient body 3 is formed between an inner cylinder 2 and an outer cylinder 1, and the slit-like throughhole 4 is formed in the rubber resilient body 3. The outer cylinder 1 is then drawn to close most of the throughhole 4. Otherwise, the outer cylinder 1 is formed by injection moulding, so the throughhole 4 is closed when it is opened by an injection pressure at the time.

Title: Pulse power supply device for electric dust collector and operating method therefor
Inventor: TOMAKI TERUO
IPC: H03K3/57
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To reduce the crossectional area of a magnetic core in a pulse transformer by detecting the magnetic density of the transformer due to the excitation of ripple voltage between a dust collection electrode and an electric discharge electrode and applying a control signal to a power control switch on a high voltage pulse generation circuit for making the switch when the magnetic flux density is reduced from a maximum value by a specified value. SOLUTION: A power control switch S2 on a high voltage pulse generation circuit 5 is turned ON by a control signal from a control part 5B, and in this case, the magnetic flux density of a magnetic core in a pulse transformer PT is detected, in terms of voltage, by voltage detection resistor R1 and R2. Further, the detected voltage is integrated by an integrating circuit IN to obtain a voltage time product corresponding to the actual magnetic flux density. Then, in a comparator CP, a voltage signal from a subtraction circuit SS is compared to a voltage corresponding to the magnetic flux density of the magnetic core in the pulse transformer PT. When the latter is lower than the former, an output signal is sent to a control signal generator CC.  The control generator CC receives the output signal and supplies a control signal to the power control switch S2 so that the switch S2 is turned ON.

Title: Method for cooling and displaying commodity and cooling storage cabinet
Inventor: OTANI MEGUMI
IPC: F25D11/00
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To contribute to leveling of a demand power by cooling a commodity to a relatively low temperature before entering a peak time zone so that the demand power becomes a peak, and setting a control temperature of a refrigerator for cooling in a display chamber for displaying the commodity to a level higher than a set temperature under control to cool the commodity. SOLUTION: A microcomputer 22 lowers a control temperature by 2 degrees from a set temperature to +3 deg.C from 22:00. Thus, a commodity temperature is lowered to +5 deg.C at 8:00. When a specific heat of a drink is 1, the overall commodity stores a sensible heat of 1,600 kcal, and maintains it to 13:00. The microcomputer 22 sets the control temperature from the set temperature to +4 degrees for 3 hours of 13:00 to 16:00 to 9 deg.C. The commodity temperature is gradually raised after 13:00, but since a capacity decrease of a refrigerator 13 for the 3 hours is provided by a thermal storage amount at the commodity, the commodity temperature is raised to +7 deg.C of a normally cooling temperature at about 16:00.

Title: Compressor
Inventor: YOSHIMURA TAKAO
IPC: F04B39/06
Filed: 1986-12-26
Abstract: PURPOSE:To lower the average temperature of a compressing mechanism section and continuously deprive the compressed gas of heat by providing a cooling mechanism heat-exchanging with the compressed gas in a compression chamber on the compressing mechanism section. CONSTITUTION:When a compressor is operated, the pressure and temperature in a compression chamber 13 gradually rise, thereby the temperature of the end plate 18a of a stationary scroll rises. The refrigerant sealed in a pipe 20 and a passage 19 is gradually gasified while absorbing heat from the end plate 18a as the temperature of the end plate 18a rises, and it reaches a radiating section 21 at the outside of an enclosed casing 1 via the pipe. Here the refrigerant radiates heat, and is liquefied and again returned to the passage 19 via the pipe 20. Subsequently this cycle is repeated, thereby the temperature of the refrigerant gas in the compression chamber 13 is lowered.

Title: Base plate type optical switch
Inventor: SAKANO TATSUYA
IPC: G02F1/313
Filed: 1988-12-10
Abstract: PURPOSE:To eliminate the necessity of alignment between an optical switch section on a base plate and an optical fiber to be connected with the switch section in the polarizing direction by providing a polarization adjusting section at part of the optical switch section on the base plate. CONSTITUTION:A polarization adjusting section 7 composed of a metallic clad 6 is provided at part of a waveguide 2 on the input side of an optical switch S2. The guided light of the light made incident on the input-side waveguide 2 usually extremely drops in extinction ratio unless single polarized light of either TE or TM is made incident, since the switch voltage is different between the TE and TM modes due to the polarization dependency on the base of the optical anisotropy of the plate side 1 because of the existence of the clad 6, but unnecessary polarized components are absorbed by the inertial effect of electric charges in the clad 6. Therefore, when an optical fiber is connected with the switch S2, no alignment is required between the main axis of the optical fiber and axis on the base plate 1 side.

Title: Electrostatic latent image developing device
Inventor: MIZUNO HIROSHI
IPC: G03G15/08
Filed: 1986-12-26
Abstract: PURPOSE:To obtain an image which has no irregularity in density by using high-resistance magnetic toner as insulating toner. CONSTITUTION:For example, the high resistance magnetic toner is used as toner. Then when the toner is supplied to a developing sleeve 40 by a toner supply roller 47, the toner is attracted to the side of the developing sleeve 40 under the influence of the magnetic force of a magnetic roller 41 and supplied deeply to a magnetic developer on the developing sleeve 40.
