Abstract: PURPOSE:To eliminate foreign matters in a light transmissible drum by setting the pressure of the inside of the drum higher than air pressure when a light transmissible original wound across the light transmissible drum is irradiated with a light source inside the drum, and it is read with a reader outside the drum. CONSTITUTION:The light transmissible drum 301 outside which a light transmissible read original 320 is wound is supported with drum supporting plates 101a, 101b at both ends. The supporting plate 101a is driven with a motor 104, a belt 105, a pulley 106, and a rotary shaft 102, which rotates the drum 301. The supporting plate 101b is supported pivotally at a bearing 103b rotatably freely, and a transmission light source arm 309 is provided in its center part so that it can be moved freely, and the light source L is provided at its tip part. The light source L is interlocked with an optical sensor outside the drum 301 not shown in figure. Air paths 108a, 108b are provided at the drum supporting plate 101b, and the pressure of the drum 301 is set higher than the air pressure by communicating the paths to an air pump 112, a pressure sensor 110, and an electromagnetic control valve 111. In such a way, it is possible to prevent an image deteriorating due to the invasion of the foreign matters into the drum.

Title: Ultrasonic object detector
Inventor: YAMANE TOSHIKI
IPC: G01S15/04
Filed: 1990-08-15
Abstract: PURPOSE:To reduce possibilities of detection errors by detecting an external noise when a senser part of a certain channel is selected by a channel changing circuit. CONSTITUTION:A wave receiving circuit 29 is connected with amplifier circuits 13a-13d of senser parts 1a-1d through an external noise wave receiving channel changing circuit 28. The external noise wave receiving channel changing circuit 28 consists of an electronic changing switch, and it is controlled for a change synchronously by a channel changing circuit 27 so as to select a channel to be selected by changing circuits 25, 26 next. Even during a period while ultrasonic pulse transmitting/receiving action is performed for a certain channel, therefore, the condition of external noise for the channel to be selected next can be received by a wave receiving circuit 29. The condition of the external noise before transmission of waves can thus be monitored, thereby detection errors by the external noise can be prevented.

IPC: C02F11/04
Filed: 1984-10-16
Abstract: PURPOSE:To enable the simplification and cost reduction of the titled apparatus, by providing a flexible bag body to the fermentation gas storage space of a methane fermentation tank. CONSTITUTION:A flexible bag body 10 is provided in a methane gas storage space 6. When the pressure in fermentation gas piping is less than reference one, this state is detected by a gas pressure detector 9 and the flexible bag body 10 is expanded to narrow the methane gas storage space to raise gas pressure. When the pressure in said piping reaches 110% of the reference pressure, a blower 12 is stopped. When the pressure in the piping exceeds the reference pressure, this state is detected by the gas pressure detector 9 and a solenoid valve 13 is opened to contract the flexible bag body 10. When the gas pressure reaches 90% of the reference pressure, the solenoid valve 13 is closed. By this method, the supply and discharge of air to the flexible bag body is performed to keep the gas pressure in piping.

Title: Phase synthesis type space diversity receiver
Inventor: WATANABE TAICHI
IPC: H04B7/08
Filed: 1988-08-31
Abstract: PURPOSE:To simplify a circuit design and a circuit constitution and to miniaturize the title receiver by setting a time constant of an automatic gain control circuit to a sufficiently large value with respect to a fundamental wave frequency of a phase modulation signal and deciding the level of the gain control signal outputted from the automatic gain control circuit at a deciding circuit. CONSTITUTION:The time constant of an existing gain control circuit 52 in a synthesis signal amplifier circuit 5 is selected sufficiently longer than the frequency of the phase modulation signal CS. Then the gain control voltage GS outputted from the gain control circuit 52 is subjected to level decision by a Schmitt trigger circuit 54 to decide the opposite phase state between a main reception intermediate frequency signal IM and a sub reception intermediate frequency signal IS. Thus, a filter circuit for frequency 2fp using an active filter to decide the opposite phase state is not required. Then the circuit design and the circuit constitution are much simplified.

Title: Abrasive and polishing method for polishing silicon wafer
Inventor: MASUMURA HISASHI
IPC: C09K3/14
Filed: 1994-09-12
Abstract: PURPOSE: To improve the efficiency of abrasive for polishing silicon wafer by preparing the abrasive by adding a specific amount of sodium aluminate to colloidal silica abrasive. CONSTITUTION: While it is preferable to control the content of sodium aluminate in abrasive for polishing silicon wafer to 0.1-2.0wt.% against the total weight of the abrasive, the more preferable and most preferable contents of sodium aluminate are 0.3-1.5wt.% and 0.9-1.5wt.%. When the content is <0.1wt.%, not much improving effect can be expected in the polishing efficiency of the abrasive and, when the content is >2.0wt.%, the abrasive becomes uneconomical, because the improving effect of the polishing efficiency becomes worse than in the case where the content is 0.1wt.%. When such abrasive is used for polishing silicon wafers, the purpose can be accomplished regardless of the kind and hardness of silicon pads. Therefore, the polishing efficiency of the abrasive can be improved, because the polishing speed of the abrasive can be increased.  In addition, the surface roughness of polished wafers dose not become worse.

Abstract: PURPOSE:To obtain an optical fiber optical modulator with high long-term reliability by applying optical modulation by means of plural light sources placed so as to allow the optical axis to be orthogonal to the center axis of an optical fiber thereby increasing the upper limit of a modulation frequency. CONSTITUTION:A light emitting element 5 having a radiating wavelength of lambda is placed to one end of an optical fiber 3 of a single mode type having a clad thickness T of 6lambda<=t<=20lambda and a photodetector 6 is placed to the other end, n-set of light sources such as He-Ne leasers having a radiation wavelength are placed to the side of the fiber 3 as modulation light sources 7...7. The light sources 7...7 are named as P1...Pn and they are flickered at a time band, then the light of wavelength lambda emitted from the light sources 7...7 enters a core 9 through a clad layer 8 of the fiber 3 and the luminous change of the modulated light source appears clearly at the photodetector side. The upper limit of the modulation frequency is increased in the optical modulation by means of the plural modulation light sources in this way because the medium is light.

Title: Air side support control method for seat and air side support device
Inventor: OGASAWARA HIROMITSU
IPC: B60N2/90
Filed: 1992-07-24
Abstract: PURPOSE:To enable compressed air to be quickly and smoothly exhausted out of right and left air chambers without making use of any external power and the like. CONSTITUTION:When compressed air is exhausted out of right and left air chambers 12R and 12L accompanied by the release of first and second valve bodies 38 and 48, compressed air from a compressor 16 is blown out as a jet in the open end section of a discharge port ZXH out of a tapered gap 58 through a third flow path 60. This situation thereby enables compressed air out of the right and left air chambers 12R and 12L to be quickly blown off out of the discharge port EXH to atmosphere while being accelerated by the suction caused by compressed air which is jetted out.
