Title: High frequency signal processor
Inventor: USUI AKIRA
IPC: H03D7/14
Filed: 1984-03-16
Abstract: PURPOSE:To attain the insertion of DC coupling and an external circuit by providing a terminal to which the external circuit is connected across a resistor connected to a base of an emitter follower circuit. CONSTITUTION:An intermediate wave signal extracted from a common collector of transistors (TR) 14, 16 is given to a base of an emitter follower TR33 via a resistor 35 being a component of the emitter follower circuit 3. Since a resistance value as high as 10kOMEGA is used for the resistor 35, a high frequency signal is almost attenuated and only a DC potential is given to the TR33. The high frequency signal component is fed to the base of the emitter follower TR33 via a frequency mixing circuit 1, a terminal C, a band pass filter 2 and a terminal D by leading out the terminals C, D to the outside of an integrated circuit from both terminals of the resistor 35 and connecting the band pass filter 2 to them.

Title: Coordinate input device
Inventor: SATO SHUNJI
IPC: G06F3/048
Filed: 1989-03-06
Abstract: PURPOSE:To eliminate the defect due to the output of the unnecessary coordinate information by inhibiting the output of coordinates to a host equipment when this equipment is set in a mode where no input of coordinates is required. CONSTITUTION:An output means detects the position of the coordinates designated on an input board surface and outputs the coordinate position to a host equipment. A setting means 80 sets the host equipment in a mode where no input of coordinates is required. Then a control means 51 inhibits the output of coordinates to an output means when the means 80 decides the unnecessity for input of coordinates. Thus the input of coordinates is permitted only when it is required by a copying machine, and otherwise the input of coordinates is inhibited. Consequently, the ineffective input of coordinates that is not desired by an operator is eliminated and the copying errors can be prevented.

Filed: 1990-03-05
Abstract: PURPOSE:To improve sealing performance by providing leather material around the external periphery of a shaft with grooves being brought into contact, also loosely fitting a cylindrical frame to it, and charging and hardening fluid binder between the leather material and frame. CONSTITUTION:A substance 2 made of leather as a sealing material is fitted around the external periphery of a shaft 1 with grooves. A cylindrical frame 3 with bottom is loosely fitted to the leather sealing material 2, and fluid-type naturally hardened resin 4 is poured between the leather sealing material and the frame 3. When this resin 4 is poured, the leather sealing material 2 is pressed and stuck to the shaft 1 due to the weight of the fluid resin 4. In this state, the resin 4 is hardened. Therefore, the leather sealing material 2 reduces the friction resistance and also improves the sealing performance.

Title: Compound semiconductor device
Inventor: MATSUI YUICHI
IPC: H01L29/205
Filed: 1985-03-15
Abstract: PURPOSE:To obtain high electron mobility even when a high electric field is applied, by providing a compound semiconductor in the second layer, which has a lattice constant layer than the lattice constants of the compound semiconductors in the first and third layers, thereby suppressing the effect of lattice scattering. CONSTITUTION:In the structure of an FET shown in the Figure, lattice constants are as follows: 6.058Angstrom  for InAs; 5.65Angstrom  for GaAs; and AlAs has 5.662Angstrom . Therefore, the lattice constant of the InAs layer 12 is extremely larger than that of GaAs and that of GaxAl1-xAs. For this reason, the cubic lattice of the InAs is deformed into the tetragonal lattice by elastic strain in the vicinity of the interface between the GaxAl1-xAs layer and the InAs layer. In this FET structure, an uppermost Ga0.7A0.3As layer 14 is made to be a complete depletion layer by controlling a voltage, which is applied on a gate electrode. Since a GaAs substrate 10 and a GaAs epitaxial layer 11 have high resistance values, the FET, in which only the InAs layer 12 is made to be the channel layer, is obtained.

Title: Cathode-ray tube
Inventor: CHIBA HIROAKI
IPC: H01J29/87
Filed: 1985-03-18
Abstract: PURPOSE:To acquire a cathode-ray tube with no generation of surface flaking or resin crack, by reducing the remaining styrene monomar after the hardening of the unsaturated polyester resin. CONSTITUTION:The unsaturated polyester resin used for an adhesive is processed to remain styrene monomer of less than 6wt% after the hardening reaction. With such a remaining quantity, it is preferable to prevent generation of the screen defection, and to keep a property of an adhesive. If the hardening is promoted 100%, with no remaining styrene monomer, the hardness and adhesion are increased, but flexibility is deteriorated, and when exposed at a high temperature, it will cause to generate surface flaking or resin crack over the face plate or the front panel. Therefore, the remaining amount of less than 6wt% should never be 0wt%.

Abstract: PURPOSE:To provide a jig for preliminary solder which can avoid adherence of a foreign matter such as solder residue, dust to an outer peripheral area of a surface side main surface or particularly a passivation film of a semiconductor chip in a preliminarily soldering step. CONSTITUTION:A jig 5 is used when a metal layer 2 metallized on a main surface of a rear surface side of a planar type semiconductor chip is preliminarily soldered. The jig 5 has a recess 5a formed on a jig body made of a material having low solder wettability with the main surface of the rear surface side directed upward to contain a semiconductor chip 1. A peripheral groove 5b for dropping a foreign matter such as solder residue, etc., is so formed at a bottom peripheral area in the recess as to be deeply dug. Accordingly, adherence of the matter such as the dust due to direct contact of an outer peripheral edge of a passivation film formed on the main surface of a front surface side with the jig is prevented in a preliminarily soldering step.

SOLUTION: Total number of turns WMa of a main coil Ma is divided into WMa1 and WMa2 , and a tap lead wire LTMa is drawn out of an intermediate point between them and led to a transfer relay Ra together with a lead wire LMa2 of the end of WMa2 . Here, WMa1 is set to the number of turns such that the motor characteristic is optimized when the power source frequency is 60Hz, and also the WMa2 is set to optimize the motor characteristic at 50Hz when the number of turns is WMa2 plus WMa1 =WMa , and the number of turns of the main coil during 50Hz is made greater than that during 60Hz. Thus, when the power source frequency is 60Hz, the power source is connected to the tap lead wire LTMa by a transfer relay Ra and is connected to the lead wire LMa2 during 50Hz.
