Title: Low-noise refrigerator
Inventor: SUGAWARA MASAMICHI
IPC: F25D11/00
Filed: 1990-05-01
Abstract: PURPOSE:To prevent the generation of howling and obtain a system never affected by sound except the noise of a machine by a method wherein the noise of the machine, which is discharged out of a heat dissipating opening opened on the wall surface of a machine chamber, is cancelled by control sound. CONSTITUTION:A vibration pickup 30 detects vibrations corresponding to noises generated from machines such as compressors 20, 21, 22 and the like. A control circuit 40 processes the output signal of the vibration pickup and drives a sound generator 50 such as a speaker and the like. According to this operation, the sound generator outputs control sounds in accordance with the noises of the machines such as the compressor and the like whereby the noise of the machine, discharged out of the opening 17 of a machine room 10, is cancelled by the control sounds. The noise S of the compressor is measured by the vibration pickup 30 indirectly and, therefore, there is no possibility of howling due to the control sound A even when the output of the sound attenuating speaker 50 is increased and the title refrigerator will never be affected by sound such as the sound of a fan, external sound and the like except the noise S of the compressor.

Title: Automatic cooler
Inventor: TAKE MASAFUMI
IPC: F25D3/10
Filed: 1989-05-10
Abstract: PURPOSE:To automatically cool and to reduce consumption of liquid nitrogen by composing the cooler from a heater power calculator, a comparator, a synchronizing pulse generator, an integrator, and a relay for turning ON, OFF power to a heater in response to the output of the comparator. CONSTITUTION:A target temperature is input to a heater power calculator 1, power to be applied to a heater 6 is calculated, and output to one input of a comparator 2. A synchronizing pulse generator 3 generates a pulse synchronized with an AC power source, inputs it to an integrator 4 to integrate the pulses, and simultaneously outputs the value to the other input of the comparator 2. The comparator 2 compares the two inputs, turns ON a relay 5 when the input from the calculator 1 is larger, and turns OFF the relay 5 when the input from the integrator 4 is larger. When the relay 5 is turned ON, power is applied to the heater 6 to vaporize the liquid nitrogen, and when it is turned OFF, power is not applied to stop vaporizing. Accordingly, the vaporizing amount regulation of the liquid nitrogen responsive to the output of the calculator can be performed.

Title: Multispan polygonal rigid-frame structure
Inventor: ISOZAKI MASANAO
IPC: E04B1/24
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To obtain a steel-framed structure having a large-sized space and aseismicity by binding two horizontal beams in the linear relationship of multispan rigid-frame structure at the end sections of two inclined sides extended from a capital and building a tension beam between binding sections. SOLUTION: Inclined beam 6 extended in two Y shapes crossed at right angles respectively are installed to a plurality of capitals 7 constituting a building structure 1 in vertical four spans and horizontal eight spans, and the end sections of orthogonal horizontal beams 2 are combined with the front end sections of the inclined beams 6 respectively. Mutually orthogonal tension beams 4 are built near the binding sections of the inclined beams 6 and the horizontal beams 2 by bolt clamping. The inclined beams 6 extended in one Y shape are used at the time of the two horizontal beams in linear relationship. Consequently, bending moment applied to each horizontal beam 2 can be decreased, and thinner H-steel can be employed. Since the length of the horizontal beams 2 can be shortened, bending moment by vertical load can be lowered.  Accordingly, the construction cost of a large-scale building structure having aseismicity can be reduced largely.

Abstract: PURPOSE:To prevent the generation of noise and abrasion of the ball of a roller bearing on an input shaft when an excessive load is applied, by allowing the inner or outer ring of the roller bearing to slip with a set torque or more, in a transmission which transmits the revolution movement of the ball to an output shaft. CONSTITUTION:The inner ring 8a of a roller bearing 8 is fitted onto the rotary shaft 6 of an electric motor, and the outer ring 8b of the roller bearing 8is inserted into the inner hole of a bracket 2. Though the revolution movement of the ball 8c between the inner and outer rings is transmitted to an output shaft 10 by a carry 9, the generation of abrasion and noise due to the idling of the ball 8c with excessive load can be suppressed markedly, since the inner and outer rings are installed onto the rotary shaft 6 and the bracket 2 in the degree where either of the rings can slip when an excessive load is applied onto the output shaft 10.
