Abstract: PURPOSE:To obtain a frequency output signal with excellent temperature characteristics, by providing a voltage controlled oscillator for reference frequency generation, summing the outputs of the voltage controlled oscillator and picking up the beat component. CONSTITUTION:A difference of oscillating frequencies of voltage controlled oscillators 2 and 4 when a control voltage on a signal line 11 is minimized, is taken so as to obtain the minimum frequency of a desired output of a signal line 17, and when this control voltage is maximum, the difference of said frequencies is taken as the maximum frequency. An output signal line 16 of an addition circuit 6 has frequency components of f1+f2 and ¦f1-f2¦, where f1 is a frequency  on a signal line 13 and f2 is that on a signal line 15. The (f1+f2) is cut off at a rectifying circuit and an LPE7 and the ¦f1-f2¦ frequency component only is obtained on the line 17. That is, the frequency output controlled with the voltage can be obtained. Since components of similar characteristics are used for the oscillators 2 and 4, the effect of temperature change can be suppressed lower.

Title: Reciprocating type refrigerating machine with built-in cold-heat storage apparatus
Inventor: GOTO TETSUYA
IPC: F25B9/14
Filed: 1989-05-29
Abstract: PURPOSE:To prevent fouling and leakage of the working gas for improving the refrigerating performance for a long term operation by furnishing a flexible diaphragm with the inner brim air-tightly fixed around the outer circumference of a rod and the outer brim fixed around the inner circumference of a first cylinder so that a compressive space, whose one end is connect to a cold-heat storage apparatus through a radiator, is formed in the first cylinder. CONSTITUTION:A flexible diaphragm 15 is deformed by reciprocating movement of a rod 11 driven by a driving unit so that the volume of a compressive space 16 is reduced, causing the working gas to be compressed in the compressive space 16. The working gas which becomes high temperature due to compression is led to one end of a cold heat storage apparatus 25 after cooled in a radiator 27, further cooled while passing through the cold storage apparatus 25 and then led into an expansion space 23 by reciprocating movement of an expansion piston 18. The working gas introduced into the expansion space is expanded and generates a refrigerating effect. The moving part which is moved by compressed air to compress the working gas includes only the flexible diaphragm that deforms but not s sliding part, that avoids abrasion which interferes with maintaining a stable refrigerating performance. Moreover, as the compressive space is of an air-tight space with the flexible diaphragm, the working gas is prevented from leaking out of the compressive space and oil and grease from intruding into the compressive space, so that a stable performance can be maintained for a long term operation.

Filed: 1989-05-31
Abstract: PURPOSE:To prevent the occurrence of a moire pattern by making the direction of a linear non-emitting area of a linear fresnel lens sheet which condenses the light emitting from an image projector different from the direction of the black stripe of a lenticular lens with each other. CONSTITUTION:In a projecting screen, the direction of the linear non-emitting area of the linear fresnel lens 4c can be slidable toward the linear direction of the black stripe of the lenticular lens. For instance, the fresnel angle phi1 and phi2 of the linear fresnel lens 4c are set at 135 deg. and 45 deg. respectively viewed from the opposite light source side. When this type of linear lens is used, the non-emitting area is in the form of a grid having the fresnel angles phi1 and phi2. Therefore, the angle of the linear non-emitting area never interferes with that of the non-parallel slit black stripe, so that the occurrence of moire pattern is suppressed.

Abstract: PROBLEM TO BE SOLVED: To make transfer defect of toner, owing to deformation of an elastic sheet of an agitating member, be prevented in a developing device. SOLUTION: The toner is contained in the toner cotainer 131 of the developing device 208. The toner 109 is transported toward a developing sleeve 105 with an elastic sheet 3, by the rotation of the agitating member 5 in the direction of the arrow (clockwise). Since unwanted deformation of the elastic sheet 3 can be prevented under the severe environment (for instance, such as high temp./high humidity, or left standing over long period) by composing the elastic sheet 3 by means of polyphenylene sulfide, regardless of a quantity of the toner 109 in the toner container 131, the toner 109 can be excellently fed on the roller 105.
