Title: Gaas monolithic amplifier
Inventor: HONJIYOU KAZUHIKO
IPC: H03F3/345
Filed: 1982-02-19
Abstract: PURPOSE:To obtain a monolithic device which is highly stable and accurate and can be gain-controlled by a method the short gate length FET of GaAs or InP is used for amplification, and the drain.source resistance of the long gate length FET of GaAs or InP is used for the load thereof. CONSTITUTION:When the source 23 of the short gate length FET for amplification is earthed, and a voltage V is impressed on the dimension L between the drain 22 and the source, the internal electric field E=V/L, and accordingly V=E is valid up to E=3kV/cm in GaAs. When the bias voltage of the gate 24 of the long gate length FET for load is varied 33-35 by setting 31 the gate bias voltage of the short gate length FET, the operation point varies 37-39, and the load resistance increases in this order. Since the FET for load is used in an unsaturation region wherein V=muE is valid, accurate resistance values can be realized over a wide range by the formation by controlling the carrier density and channel thickness. Thus, a monolithic amplifier of a wide band which is demanded for accurate gain control can be obtained.

Title: Detector for leakage from pipeline
Inventor: FUKUDA TOSHIO
IPC: G01M3/28
Filed: 1979-03-06
Abstract: PURPOSE: To detect slight leakage from a pipe line in an on-line manner, by attaching pressure gradient detectors to the upstream and downstream sides of a pipeline, connecting a leakage detection index calculation circuit to the detectors and coupling a leakage judgement circuit to the calculation circuit.  
     CONSTITUTION: Pressure gradient detectors 11, 12 are attached to the upstream and downstream sides of a pipeline 10. Pressure gradient fluctuation detected by each detector is amplified and subjected to an A/D conversion so that n pieces of signals  Pi per a short period of time are stored in data buffers I, II. n Pieces of signals Pi  picked out of the buffers are applied to a leakage detection index calculation circuit  to compute a leakage detection index. A leakage judgement circuit judges from the  index whether there is leakage. When the circuit judges that there is leakage, it is  indicated. The leakage from the pipeline can thus be easily detected.

Filed: 1988-02-08
Abstract: PURPOSE:To remove the enclose of a light beam and to prevent a scanning line on a photosensitive body from being a hyperbola by making a normal from the surface apex of a reflecting surface not pass the center of rotation and shifting each normal in the same direction by the same angle in a plane including each normal. CONSTITUTION:On the reflecting surface 11, the normal NL which passes the surface apex C positioned in the center of the end parts A and B thereof is shifted by a specified distance l1 in order not to pass the center O of rotation of a polygon mirror 1 and the reflecting surface 11 forms a part of a circumference with a point P on the extension of the normal NL as a center. The light beam LB is shifted a specified distance l2 from the center O of rotation to the polygon mirror 1 and is made incident toward a point on a opposite side by putting the center O of rotation between the normal NL from the surface apex C of the reflecting surfaces 11-18 and said beam LB. At the time of rotating the polygon mirror 1 a specified angle by a specified angle, the width of variation in a distance between the image-formation point and the surface of the photosensitive drum 6 is small. Thus, the photosensitive drum 6 is exposed with the light beam whose spot diameter is uniform.

Title: Film coating material and its production
Inventor: NISHIYAMA SATORU
IPC: C23C14/22
Filed: 1992-01-17
Abstract: PURPOSE:To form a coating film excellent in adhesive strength without high temp. treating by forming a base film containing the structural elements of a film between a base body and the film. CONSTITUTION:Without directly forming a desired film 4 on the surface of the base body 2, the base layer 6 containing the structural elements of the desired film 4 is interposed between the base body 2 and the film 4. A mixing layer made from the structural elements of both the base body and the film is formed near the boundary of the base layer 6 and the base body 2. By this method, since the mismatch in coefficient of thermal expansion or lattice constant between the desired film 4 and the base layer 6 is prevented and internal stress generated in both films is reduced, the adhesive strength is drastically improved. Furthermore, the mixing layer 8 acts just like a wedge and reduces the internal stress generated in the base film 6.

Abstract: PROBLEM TO BE SOLVED: To enable contents to be kept cool for a long time by a light and compact means by making the inside of a storage chamber at a negative pressure by a pressure-reducing means attached to a cold box when the cold box having the storage chamber inside is kept cool. SOLUTION: At the time of using the cold box, first, ice or other refrigerant is put in a storage chamber A and a lid 4 is closed, so that a temperature in the storage chamber A is lowered approximately uniformly. After the lid 4 is opened and caught fish or the like is put in, the lid 4 with a rubber packing 4a as a sealing means is closed, and it is locked to a box body 3 by a stopper 5. Thereafter, a pump 1 is operated to discharge a part of air in the storage chamber A out of the cold box, thereby making a negative pressure inside the storage chamber A. The negative pressure can be maintained even after the pump stops by providing a check valve at an exhaust port.  At the time of taking out contents, an atmosphere flow-in hole 7 is opened by removing its plug 9 to have an atmosphere flowing into the storage chamber A, whereby the inside of the storage chamber A is returned to a normal pressure to allow the lid 4 to be opened.
