Title: Leakage steam disposal system of steam turbine shaft sealing section
Inventor: SATOU YOSHIAKI
IPC: F01D11/06
Filed: 1981-12-15
Abstract: PURPOSE:To simply and certainly prevent steam leakage by connecting a leakage steampipe through a steam ejecter to an apparatus equipped with a pressure source below the atmospheric pressure during normal operation and operating driving steam on the steam ejecter according to a change of pressure in said apparatus. CONSTITUTION:Leakage fluid from the packing part of a shaft sealing section of a steam turbine 1 which is most adjacent to the open air is introduced into a condenser 5 by means of a leakage pipe 2 through a steam ejecter 6. The steam ejecter 6 is provided with a steampipe 7 to introduce driving steam through a steam valve 8. By opening the steam valve 8 prior to vacuum rise in the condenser 5, driving steam is supplied to the steam ejecter 6 and leakage fluid from the shaft sealing section of the steam turbine 1 is discharged into the condenser 5 via the leakage pipe 2. Thus, the interior of a turbine casing is shut out from the open air, which is prevented from flowing into the condenser 5 from the shaft sealing section of the turbine through the turbine casing.

Title: Optical apparatus
Inventor: OHARA TORU
IPC: G02B7/02
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To provide an optical apparatus capable of position control of a moving lens group, which can detect temp. with high accuracy in spite of having a simple structure and is not affected by an environmental temp. change, by providing the apparatus with an arithmetic means which calculates temp. change rate by using the absolute temp. value, etc., to be reference, and supplying these values to a movement control means for a moving lens. SOLUTION: The ambient temp. at the time of apparatus assembly is written as a reference value as the absolute temp. into an EEPROM 112 and simultaneously the temp. in a temp. detecting sensor 110a is detected as a relative temp. value and is written therein. When a power source is turned on after shipping, the work is thereafter executed automatically. The 110 a output from the temp sensor of the temp. detecting means is read into a microcomputer 120 and is stored in a memory means 123d. Next, the reference value of the absolute temp. and the relative temp. value already read into the EEPROM 112 are fetched. These values, the relative temp. value stored in the memory means 123d and the information from the temp. detecting sensitivity 122a are drawn out and are subjected to computation, by which the temp. change rate is calculated.

Title: Copying method
Inventor: SAITOU ITARU
IPC: G03G21/00
Filed: 1983-10-27
Abstract: PURPOSE:To obtain always stable and good pictures by fatiguing forcibly a photosensitive body having an As2Se3 photoconductive layer before copying. CONSTITUTION:A suberaser 11 which irradiates a light having about 700nm wavelength at least is provided adjacently to a main eraser 10 in the rotation direction of a photosensitive body 1. The photosensitive body 1 having the As2Se3 photoconductive layer is fatigued forcibly by the light having about 700nm wavelength. Though the photosensitive body 1 is fatigued even by the light which does not include about 700nm wavelength, the degree of fatigue in this case is low, and light sources emitting the light which does not include about 700nm wavelength are used as the main eraser 10 and a destaticizing lamp 6. When the photosensitive body 1 is much fatigued by the stop time, the photosensitive body 1 is idled under light irradiation of another light sources such as the main eraser 10 before the copying operation. When the photosensitive body 1 is less fatigued, the suberaser 11 is lit, and the photosensitive body 1 is idled under light irradiation of the suberaser 11. Thus, a stable surface potential is always secured independently of the stop time.

Title: Surface shape measuring device
Inventor: NISHIZAWA AKIRA
IPC: G01B7/34
Filed: 1988-08-17
Abstract: PURPOSE:To measure the surface shape of an object to be measured by providing an observation device for observing a change in the detection output from an amplifier. CONSTITUTION:In measurement, a detection element 3 to which a predetermined weak current is applied is allowed to approach the surface 2a of an object 2 to be measured at first. Next, the object 2 to be measured is gradually moved in the horizontal direction shown by an arrow A and the change of the detected current obtained by gradually scanning the surface 2a of the object 2 to be measured by the detection element 3 is observed on an oscilloscope to measure the shape of the surface 2a of the object 2 to be measured. Since the detection element 3 is constituted so that a conductor part 8 is supported by a support part 9, the contact pressure applied to the leading end part of the detection element 3 is divided by the conductor part 8 and the support part 9 and, therefore, the contact pressure applied to the conductor part 8 is reduced. By this constitution, the detection element 3 becomes hard to be damaged and the surface shape of the object 2 to be measured can be accurately measured.

Filed: 1984-09-29
Abstract: PURPOSE:To keep temperature inside the system within a fixed range, by installing an air discharge-intake mechanism in a condenser lower part of an evaporative cooling device, while opening the said mechanism in times of abnormally high and low temperatures. CONSTITUTION:A solenoid valve 23 is installed in a position between a lower tank 14 at the lower part of a condenser 3 of an evaporative cooling device and an atmospheric part of a reservoir tank 20. And, a temperature sensor 11 is installed in a water jacket 2. Here, when the inside of a system comes to abnormally high temperature due to continuation of high load operation for hours, the solenoid valve 23 operates whereby the lower part of the condenser 3 is interconnected to an ambience of the atmosphere. Therefore, air inside the condenser is pushed out at a stretch by dint of internal steam pressure. On the other hand, when the inside of the system comes to abnormally low temperature, the solenoid valve 23 as an air intake mechanism operates whereby air is inhaled in the condenser 3 in a state of being decompressed, covering a part of the condenser, so that an effective radiating area is reduced.
