Title: Dot position accuracy stabilization of led printing head
Inventor: EBINAKA TOSHIO
IPC: B41J2/455
Filed: 1990-06-14
Abstract: PURPOSE:To enable correction of a misalignment of the light emitting position of an LED array due to thermal expansion by providing a mask with an opening against each chip of the LED array in an opposite position to the LED array with a specified number of LED array chips aligned in a longitudinal direction and forming a recording dot using only a light beam, from an LED array chip, which passes through the opening. CONSTITUTION:The center of a light emitting surface 16a of LED array chips arranged on an LED array surface and the center of an opening 27a on a mask 27 are aligned on a single axis. Subsequently, the center of a primary light beam 26 projected by light emission of the LED array chip passes through the center of an opening 27a in the mask 27. Then the secondary light beam 26a which is made constant in the opening 27a reaches an image focusing surface 3a to form an optical image S1. If the image focusing surface 3a of a photosensitive element which is photoconductive is electrically charged uniformly and is allowed to move(rotate) at a peripheral speed V, the volume resistance of part of the photosensitive element where the optical image S1 is formed decreases below a threshold value Rth of the volume resistance required for formation of a latent image and subsequently the photosensitive element is electrically discharged. Thus a specified latent image is formed on the photosensitive element.

Title: Turning stall preventing device for compressor
Inventor: ISHII HIROSHI
IPC: F04D27/02
Filed: 1990-06-15
Abstract: PURPOSE:To prevent turning stall generated around a surge of a high pressure ratio immediately after its generation by a simple control circuit so as to obtain a compressor of high reliability by judging a signal from a shaft vibration sensor mounted onto the body outer side of a compressor to open a blow-off valve. CONSTITUTION:A shaft vibration sensor 7 detects the shaft vibration of a compressor 1, and a filter circuit 8 cuts the high frequency noise of a signal outputted from the shaft vibration sensor 7. A rectifier circuit 9 converts an a.c. signal into a specified d.c. signal corresponding to the grade of its amplitude and outputs it into an output discriminating circuit 10. The output discriminating circuit 10 generates constant voltage exceeding the preset reference voltage value according to the grade of input voltage. On the other hand, an actuator 6 is operated only when a signal is inputted from the output discriminating circuit 10 to open a blow-off valve 5. Accordingly, when large shaft vibration due to turning stall is generated, the blow-off valve 5 is opened to lower the pressure of the compressor 1 suddenly and thereby to place the compressor 1 into the unloaded state. Turning stall can be therefore avoided immediately after its generation.

Abstract: PURPOSE: To prepare the titled compound in high yield, by adding a specific amount of an alkali together with water to the reaction system of hydrolyzing a polyether prepared by polymerizing tetrahydrofuran, etc. in the presence of a ring-opening polymerization catalyst such as fuming sulfuric acid, thereby carrying out the complete hydrolysis without using a large amount of water.  
     CONSTITUTION: A polyether glycol is prepared by the hydrolysis of a polyether obtained by the polymerization of tetrahydrofuran or its mixture with other copolymerizable cyclic ethers in the presence of a ring-opening polymerization catalyst composed mainly of fuming sulfuric acid or fluorosulfuric acid. In the above process, an alkali (e.g. alkali metal hydroxide, ammonia, etc.) is added to the hydrolyzation reaction system. The amount of the alkali is ≥1/4, pref. ≥1/3 of the amount necessary to neutralize the mixture of fuming sulfuric acid, fluorosulfuric acid and water used in the polymerization reaction, and less than the amount to keep the pH of the hydrolyzation reaction system below 3. Since the solubility of the polyether glycol in the acidic aqueous solution is remarkably reduced, the considerable lowering of the yield can be prevented.
