Title: Electric field effect type pressure sensor
Inventor: AKIYAMA HISASHI
IPC: G01P15/12
Filed: 1985-12-20
Abstract: PURPOSE:To make it possible to suppress the change in output due to the change in temp. or a secular change, by detecting the pressure difference between a measuring atmosphere and a cavity chamber as the change in the drain current of an electric field effect transistor. CONSTITUTION:A lower gate electrode 7 is formed on the gate insulating film 5 of an electric field effect transistor and a spacer 11 is further applied to said electrode 7. Next, the spacer on the gate region is removed by etching and an upper gate electrode 6 comprising a metal film is subsequently formed on the residual spacer 11. A fine aperture 9 is preliminarily opened to a silicon substrate 1 to communicate a cavity chamber 8 with the outside. By the above mentioned constitution, a pressure sensor grasps such a state that the electrostatic capacity of a condenser constituted of a lower gate electrode 7 and an upper electrode 6 changes by pressure difference 10 across the cavity chamber 8 above the gate region of the electric field effect transistor as the output change of the electric field effect transistor, that is, the change in a drain current to detect pressure. By this method, the output change of a sensor by temp. change or a secular change can be suppressed.

Title: Method and apparatus for detecting liquid amount
Inventor: HOCHIDO YUKO
IPC: G01F23/14
Filed: 1989-11-06
Abstract: PURPOSE:To detect the amount of a liquid correctly by measuring pressures of a low part and an air part above the liquid surface by a pair of metallic sealed pressure detecting elements thereby to detect the amount of the liquid by the pressure difference. CONSTITUTION:A pressure detecting part 5 is provided at an air part above the liquid surface of a stainless sealed container 1 containing the liquid, while a pressure detecting part 4 is provided at a low part of the liquid. When an inactive gas is introduced from a guide port 2, a liquid surface 6 is added with the pressure, thereby allowing the liquid to be discharged from an outlet port 3. Since the pressure at the low part is reduced in accordance with the fall of the liquid surface, the amount of the liquid can be detected by detecting the change of the pressure difference.

Abstract: PURPOSE:To prevent generation of clogging in a fixed bed by floating of deposited sludge by juxtaposing plural pieces of inverted V-shaped baffle plates at suitable spaced intervals in the transverse direction to the lower part of a biological reaction vessel thereby segmenting the fixed bed to a settling region and a concentrating region. CONSTITUTION:Plural pieces of the equilateral or scalene baffle plates 10 having the inverted V-shaped section and having discharge holes at the vertex or near the same are provided in the biological reaction vessel 1a in such a manner that the respective baffle plates 100 are paralleled in the transverse direction thereof, are partly overlapped via the spacings in the vertical direction and are fixed at both ends in the longitudinal direction to the inside wall in the lower part of the fixed bed 4 in the vessel 1a. The lower part of the fixed bed 4 is classified to the settling region 11 and the concentrating region 12 by such baffle plates 10. The sludge settling from the waste water admitted into the settling region passes the spacings between the baffle plates or the spacings between the baffle plates 10 and the inside surface of the vessel 1a. The respective baffle plates are so disposed that these spacings do not act as the passage for the sludge which deposits in the concentrating region then floats. As a result, the generation of the clogging in the fixed bed by floating of the deposited sludge is obviated.

Title: Data base management method and system
Inventor: TSUCHIDA MASASHI
IPC: G06F15/177
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To decrease the quantity of data to be stored and to reduce the unbalance of load to every data storing area by securing correspondence between a data storing area and a divided key range. SOLUTION: An IOS(input/output server) 70 decides the number of areas to be divided of a disk 80 for management of it according to a load pattern that is designated by a user. The ratio of 1:4:1:8 is decided among the FES(front end server), BES(back end server), IOS and disk respectively. In an initial data loading mode, however, just a single unit of both FES and BES is enough and the said ratio is changed into 1:1:1:8. Then the load is light, only a BES 731 accesses the data bases of disks 811 to 842. Then the load is increased and the unbalance of load is detected, a BES 732 is added to change the said ratio into 1:2:1:8. Thus, the number of BESs is increased or decreased according to the load to attain a scalable system among the FES, BES, IOS and disk set in the ratios of 1:1:1:8 to 1:4:1:8.

These transmitted beams are reflected on a stepped reflecting surface end the optical path difference, i.e., the time delay is caused between the beams at a fixed interval. Then these beams are condensed on the same optical path by a collimator lens 3 via the modulator 4. These condenced beams have the time delays at the fixed intervals end therefore a time series pulse train 7 is generated.
