Inventor: ARAI KENJI
IPC: C07C323/22
Filed: 1987-12-24
Abstract: NEW MATERIAL:The compound of formula I (X is lower haloalkyl or lower haloalkoxy; R<1>-R<3> are H or CH3; R<4> is lower alkyl or lower alkoxymethyl). EXAMPLE:1-Acetoxy-5-[2-(4-trifluoromethylphenylthio)ethyl]-1-cyclohexe n-3-one. USE:A production intermediate for herbicide.

Title: Controller
Inventor: SUGIHARA YOSHIRO
IPC: G05B11/36
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To hold a response characteristic to be constant even in an excessive state in a controller controlling the feedback of one control object with plural operation parts. SOLUTION: The operation parts 3a and 3b of a control object 1 are controlled by a main control loop system 5a and a sub-control system 5b. The main control loop system 5a operates an operation value from a deviation between a measurement value PVM from the operation part 3a and a target value SVM, limits it and outputs it to the operation part 3a as main operation output. The sub-control loop system 5b operates the operation value from the deviation between the measurement value PVM from the operation part 3b and the target value PVM, adds a main limit output value, outputs the limited sub-limit output value to the operation part 3b as sub-operation output and outputs an excess exceeding a limit value. When the excess exists, the main control loop system 5a suppresses the pertinent operation output and outputs it to the operation part 3a.

Title: Heat storage tank
Inventor: TANAKA AKIRA
IPC: F28D13/00
Filed: 1989-12-19
Abstract: PURPOSE:To remarkably improve the heat storage efficiency by a method wherein the up and down motion of horizontal partition plates arranged in small heat storage compartment prevents the liquid, which is supplied for storing heat, from being mixed with the stored liquid to be discharged as low as possible. CONSTITUTION:The warm water enters a small heat storage compartment 8 from an inlet 17a. In a heat storage tank 1, relatively low temperature water (at least lower than 30 deg.C) is stored. In this state, all horizontal partition plates 26, 27, and 28 are floating due to buoyancy, and located at the upper ends of small heat storage compartments 8, 9 and 10. When, the warm water flows in from the inlet 17a, the partition plate 26 first sinks in the warm water zone as the specific gravity of the partition plate is larger than that of the incoming warm water. When the warm water is fed further, the warm water flows into the small heat storage compartment 9 through a clearance 2. When the warm water enters, the horizontal partition plate 27 begins to sink as less buoyancy acts on the horizontal partition plate 27. As this process continues, the warm water enters the small heat storage compartments 9 and 10 and the stored water is gradually replaced with the incoming warm water.

IPC: H01L21/06
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To provide a multi-stage amplifier with high gain and low power consumption. SOLUTION: This multi-stage amp].ifier includes a plurality of self-aligned metal semiconductor field-effect transistors (MES FETs) 203 having source and drain formed by self alignment, and a plurality of recessed MES FETs 20R having a gate electrode formed in a portion recessed on the surface of a channel region. The recessed MES FET 20R is used on the final stage. Although depending on the conditions, more recessed MES FETs 20R are used in a portion closer to the final stage, and the self-aligned MES FETs 20S are used in the other portions. On the assumption that the MES FETs have the same gate width, the self-aligned MES FET 20S has a higher gain but lower drain pressure resistance and a narrower linear region than the recessed MES FET 20R.  Therefore, with this structure, a multi-stage amplifier with low distortion, high gain and low power consumption in which space saving is realized may be provided.

Abstract: PURPOSE:To aim at shortening a positioning distance and a scan waiting time by changing over the operating direction of a document feed means so as to allow the trailing end of a document fed from a paper feed bed onto a document setting bed to abut against a stopper for positioning the document. CONSTITUTION:A document D is fed onto the surface of a document setting glass pane 3 from a paper feed bed 100 by way of rollers 101, 107, 108 and a pair of rollers 105 and as well by means of a feed roller 93 in a document feed means 93. In this period, at a position where the trailing end of the document D comes to a position slightly before a movable stopper 104, the feed direction of the feed roller 93 in the document feed means 99 is reversed so as to allow the trailing end of the document D to abut against the movable stopper 104 for positioning the document. In this condition a platen sheet 83 presses the document D, and an exposure means scans the document. Thus, it is possible to shorten the moving distance of a document in order to reduce contamination on surfaces adapted to make contact with a document, and further to shorten the waiting time until the scan is initiated.
