Title: Estimation method of semiconductor device
Inventor: MIMINO YUTAKA
IPC: H01L21/66
Filed: 1991-02-15
Abstract: PURPOSE:To obtain a method of estimating high frequency characteristics of a Schottky field effect transistor by detecting defects of a gate causing the deterioration of high frequency characteristics by using a method easy to be automated, relating to a method of estimating high frequency characteristics of a Schottky field effect transistor by measuring the gate resistance of a Schottky field effect transistor having a multilayered gate electrode constituted of gate metals of two or more layers. CONSTITUTION:In a Schottky field effect transistor having a multilayered gate electrode 4 constituted of gate metals 4a, 4b of at least two layers, the measuring current which is made to flow through a Schottky contact region 5 in the forward direction of the Schottky contact region 5 is set smaller than the saturation current of a channel of the Schottky field effect transistor. The measuring current is made to flow in the forward direction, in the manner in which the resistance generated in the Schottky contact region 5 by the measuring current is sufficiently small as compared with the gate resistance. By measuring the gate resistance in the above state, high frequency characteristics of the Schottky field effect transistor is estimated.

Title: Liquid jet recorder
Inventor: TAKEKOSHI NOBUHIKO
IPC: B41J2/05
Filed: 1990-02-02
Abstract: PURPOSE:To correct image quality density irregularities and prolong the life of a recording head by applying an electric energy in a pulsed waveform corresponding to the critical liquid jet voltage for each of a plurality of nozzles, to each nozzle. CONSTITUTION:A critical voltage for liquid discharge can be made uniform for each nozzle to the specified limits of an input pulse width for each nozzle. Ink is heated by the turning ON of a drive transistor 27 in response to an ON state of an AND gate 28 and ink droplets are discharged. A strobe signal consisting of a pulse corresponding to the intrinsic pulse width of each nozzle is input to the one input terminal STB of each AND gate 28. On the other hand, the data entered in a shift register 30 by a clock signal which is input to a clock input terminal Clock from the data input terminal Data of the shift register 30 is entered into the other input terminal through a latch 29. Subsequently, the width of the pulse Vth applied to the heating element 26 of each nozzle is controlled so that the width becomes uniform. Thus it is possible to make the image uniform and prolong the life of a recording head.

Filed: 1990-02-02
Abstract: PURPOSE:To make possible high-speed recording of a high-quality image using a compact device by sequentially selecting electrothermal conversion elements at a specified interval of number out of a plurality of electrothermal conversion elements, and transferring a batch of recording data signals to a recording head prior to driving. CONSTITUTION:The timing generation circuit 22 of a head drive circuit 20 generates a pulse width setting signal ENB, signals SEL 1 to m which select the position of a latch in a latch circuit 5 and select between electrothermal conversion elements 2 driven in each block, and a latch signal LAT 2. A recorded data division-generation circuit 24 extracts and recompiles recorded data corresponding to the elements 2 driven simultaneously from a single line of recorded data S11, and connects a signal S12 and a clock signal CLK 2 to a recording head drive IC 3. A single line of recording is performed by repeating the input of each signal by the number of elements constituting each block. Thus the problem of density irregularities generating in a recorded image can be solved.

IPC: H01L31/06
Filed: 1985-02-07
Abstract: PURPOSE:To improve the curve rate FF of a V-I curve while enhancing performance as a solar cell by using HgTe or a mixture containing HgTe as a CdTe side electrode for the solar cell. CONSTITUTION:A CdS film 2 is formed onto a transparent substrate such as a transparent glass substrate 1 through a method, such as evaporation, spraying, sputtering, printing, baking, etc., and a CdTe film 3 is shaped through one of these methods onto the film 2.

Title: Method for forming glass
Inventor: MAEDA SHUHEI
IPC: B29C45/02
Filed: 1992-02-07
Abstract: PURPOSE:To enable the forming of a formed product in a complicated shape and improve the quality of the formed product with high dimensional accuracy. CONSTITUTION:A raw material in an unmolten state is fed into a plunger chamber 14 formed in a cylinder 13 and heated only near a nozzle 20 in the plunger chamber 14. In this case, since the heating is carried out by induction heating, the raw material is rapidly melted. The molten glass is then pressed by a pressing means, directly injected from the nozzle 20 and filled in a cavity 28 of a forming mold 22 arranged oppositely to the nozzle 20. Since the glass in a state of not a massive form but in the molten state is fed into the cavity 28 of the forming mold 22, the freedom of shape is great and a formed product of a complicated shape can be formed. A solid product can further be formed.

Abstract: PURPOSE:To measure the thickness based on the shape of an upper surfaces, by detecting a signal corresponding to the distance between specified sides of a material to be measured supporting on a table, by an image sensor provided so as to face the table. CONSTITUTION:Under the state the material to be measured P is set on the table 1, a starting command C is given to a controller 7. Then a lamp 5 is lit and the material P to be measured is irradiated by the light. The reflected light is inputted into the image sensor through a lens system 3. Based on the starting command Z from the controller 7, a sensor driving circuit 6 gives transfer pulses X to the image sensor 4, and electric charges are written into a resister part. Based on shift pulses Y from the driving circuit 6, output pulses F are outputted to a register part and counted by a counter 9 through a wave forming circuit 8. Since the material to be measured P has a constant width, the counted value is varied in correspondence with the thickness G of the material. A thickness converter 10 reads out the true thickness stored in an ROM, and displays the value on an display device 11.

Title: Propylene copolymer
Inventor: KAMIYAMA MASAKI
IPC: C08F8/00
Filed: 1983-02-16
Abstract: PURPOSE:A copolymer excellent in impact resistance, thermal shrinkage resistance, stretchability, transparency, and rigidity and having specified stereoregularity, prepared by copolymerizing propylene with 1-butene. CONSTITUTION:A PP copolymer having a 1-butene content (Bc) of 0.1-2.5mol% and an isotacticity value (Iso) in the range of formula I when Bc is in the range of 0.1<=Bc<=0.3mol%, or in the range of formula II when Bc is in the range of 0.3<Bc<=2.5mol%. Although a propylene copolymer containing 1-butene as a comonomer has better rigidity than a PP copolymer whic is formed by copolymerization with ethylene, it shows a great decrease in rigidity when its 1-butene content exceeds 2.5mol%, and so can only form a stretched product of weak nerve. Further, propylene copolymers having an Iso value lower than any of the ranges of formulas I and II can only provide stretched products showing insufficient rigidity and weak nerve. The titled propylene copolymer can be desirably used in variety of uses such as stretch tapes, packaging films, and containers.
