Title: Manufacture of thermoplastic resin sheet and device thereof
Inventor: SAITO SHUN
IPC: B29C48/08
Filed: 1986-03-01
Abstract: PURPOSE:To prevent the quality of a thermoplastic resin sheet from lowering and contrive to reduce the energy to heat and melt chips during an extrusion process by a method wherein a passage, through which dried thermoplastic resin raw material passes, is lagged or heated. CONSTITUTION:A heating mechanism 7 consists of a pipe 71 which is windingly provided round the outer wall of a transporting pipe 4, a heating steam feed mechanism 72 to supply heating steam in the pipe 71 and insulating material 73 with which the pipe 71 and the transporting pipe 4 are wrapped. Thermoplastic resin chips, which are supplied from a storage tank 1 to a drying mechanism 2, are dried, while agitating, for example, at a temperature which is comparatively high provided below the melting temperature of the chip. After being dried at a drying mechanism 2, the chips are transported through the transporting pipe 4 to an extrusion mechanism 3. The transporting pipe 4 is heated up to a temperature such as about 140-180 deg.C by circulating heating steam, which is supplied from a heating steam feed mechanism 72 in the pipe 71 so as to pass the dried chips through the transporting pipe 4 in the above- mentioned heated state in order to transport them to the extrusion mechanism 3.

Abstract: PURPOSE:To form an active layer only on the upper surface of a mesa stripe under good controllability by growing in crystal two layers on a GaAs substrate, then performing the mesa stripe processing and then growing in crsytal the respective layers on a substrate. CONSTITUTION:An n type GaAs layer 22 and an n type GaAs layer 23 are sequentially formed on an n type GaAs substrate 21 of (001) plane. Then, mesa stripe processing is performed in depth reaching the substrate 21 so that the  (111) plane becomes side surface, thereby forming a mesa strip. Second crystal growth is performed on the substrate processed with the stripe, and an n type GaAlAs layer 24, a P type GaAlAs layer 15, a p type GaAlAs layer 26 and an n type GaAs layer 27 are sequentially formed. According to this method, the control of the width of the upper mesa surface can be facilitated, and only the thickness of the layer 24 may be noticed. Accordingly, the width of the active layer 25a made of the layer 15 can be formed with good reproducibility and good controllability.

Title: Thermal sensor
Inventor: WADA TAKETSUGU
IPC: G08B17/06
Filed: 1988-02-24
Abstract: PURPOSE:To obtain a highly reliable thermal sensor by generating a signal from a fire signal output circuit when the inclination of the sampling value of an A/D converting circuit output exceeds a prescribed value. CONSTITUTION:The voltage change of a sensing element 1 in which an electric resistance changes according to a temperature is converted into a digital signal by a resistance/voltage converting circuit 2 and an A/D converting circuit 3. The output of the A/D converter 3 is sampled at every constant time, taken into a CPU circuit 4, and when the temperature inclination of a sampling value exceeds the prescribed value, the fire signal is generated from a fire signal output circuit 5. Thus, the highly reliable thermal sensor can be presented which is completely free from incompatible conditions such that erroneous sounding increases when a time until the alarm sounding is shortened, and since the alteration of setting by a program is facilitated, it can be applicable to the circumferential conditions.

Title: Information conversion system and magnetic recording and reproducing device using it
Inventor: OTA MASAYUKI
IPC: H03M7/14
Filed: 1992-02-28
Abstract: PURPOSE:To generate a pilot signal for tracking control and to control a DSV optionally by providing 1st and 2nd prescribed information conversion means to the device. CONSTITUTION:When a 12-bit information word is converted into a 14-bit code word, a code whose CDS is 0, + or -2 in which number of consecutive same levels is 1 or over and 5 or below is employed for the code word after NRZ2 modulation and coding is implemented while controlling the CDS to suppress the divergence of the DSV. Thus, the DC free modulation system is realized. Furthermore, 1-bit is added to the 14-bit code word in an area to which a pilot signal is written and a code word whose CDS is + or -1 is used and modulation is implemented to allow the DSVB to be fluctuated synchronously with a DSV control signal thereby obtaining a pilot signal for tracking control.

Title: Air-core reactor
Inventor: MISAWA KAZUTAKA
IPC: H01F30/08
Filed: 1985-03-04
Abstract: PURPOSE:To obtain a resistance value whose ratio to reactance is large enough even if standard wires are employed by a method wherein an air-core reactor is constituted by a plurality of coaxial air-core coils whose directions of the windings are opposite to each other and at the same time the respective coils are connected to each other in parallel. CONSTITUTION:If air-core coils 1 and 2 have directions of wirings opposite to each other and are arranged coaxially, the fluxes generated by the two air-core coils 1 and 2 cancel each other. Therefore, a resultant reactance X' of the two coils is approximately 10% of the reactance of a single air-core coil. At the same time, as the respective air-core coils 1 and 2 are connected in parallel, a resultant resistance value R' is approximately a half of the resistance of a single air-core coil. Therefore, R'/X' is approximately 1.5/10 or 0.15. A mutual coupling coefficient of the two air-core coils which determines the resultant reactance can be chosen to be an optional value close to one by selecting average diameters or the like properly so that the resultant resistance can be so designed as to have a required value against the resultant reactance.

Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a TFT using a side wall, wherein the TFT is enhanced in offset length, and low-concentration source/ drain regions can be enhanced in length even if a gate electrode is lessened in thickness so as to lessen the surface of the gate electrode and a sccanning line in level difference. SOLUTION: Impurities are introduced using a side wall 15 and a gate electrode which is kept large in thickness yet and formed of a resist layer as a mask. Meanwhile, a semiconductor film 11P is covered with a gate electrode 13N in a P-type TFT forming region. After impurities are introduced into a first semiconductor film 11N, the gate electrode 13N is thinned together with the conductor film 130P. Therefore, even if the first gate electrode 13N is formed thick to make a side wall 15 long in a direction of channel so as to enhance a TFT in offset length, the gate electrode 13N is lessened in thickness after impurities are introduced, so that the gate electrode 13N is small in surface level difference.

Abstract: PURPOSE:To enable slurry excellent in fluidity and stability to be adjusted with a proper dispersed condition of fine grains by providing a means which controls a difference of measured viscosity changing a shear rate of the coal- water slurry so as to be within a fixed range. CONSTITUTION:Viscometers 10 and 11, measuring viscosity of slurry D under a condition of different shear rate, and a control unit 15, controlling a difference of viscosity, measured by the viscometer, so as to be in a range of 1000-5000cp, are provided in a pipe line 8 connecting a line mixer 7 to a distributor 9.

Title: Image former
Inventor: SEKINE YOUICHI
IPC: B41J2/065
Filed: 1978-04-13
Abstract: PURPOSE:To obtain recording images of high quality free from unevenness and thinning by disposing separate magnetic poles near the magnetic pole face supporting built-up ink, reducing the radius of the end of the build-up of the ink and increasing recovery rate. CONSTITUTION:When another magnetic poles 11, 12 are disposed near the magnetic pole face supporting built-up ink, the magnetic lines 10 of forces from the magnetic pole face supporting the built-up ink become crest form by the effect of the magnetic poles 11, 12. The built-up shape of the magnetic fluid formed by these magnetic lines of force yields the built-up form of a small build-up end radius without any constriction owing to the effect of the magnetic poles separate from the magnetic pole face. In addition, when the built-up ink 13 flies for the purpose of recording and is thus consumed, the new ink 13 is replenished by magnetic force from a felt 14, thus the recovery speed for recovering the build-up form may be increased. In this way, the recording images of high quality may be obtained at a high speed.
