Title: Motor speed controller
Inventor: ICHIYANAGI TOSHIICHI
IPC: H02P7/29
Filed: 1977-11-28
Abstract: PURPOSE: To improve response by comparing the size of the wavelength of the signal having the wavelength corresponding to motor rotary speed and that corresponsing to reference speed and determining motor current application.  
     CONSTITUTION: The rotary speed signal of a motor output from a frequency generator 1 is converted into a square wave signal B in a wave forming circuit 3. A pulse forming circuit 5 synchronizes with the rise of the square wave signal B and outputs a signal pulse E. A monomultivibrator synchronizes with the fall of the square wave signal B and outputs one pulse F. AND gates 6 and 9 set and rest the bistable multivibrator 7 by the AND against the pulse F and the AND of the single pulse E through the single pulse E and inverter 10 and controls the current application to the motor 2.

Title: Thin-film resistor, forming method thereof and strain gauge using the same
Inventor: OGAWA MINORU
IPC: H01C17/12
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To obtain a thin-film resistor with a small temperature coefficient of resistance(TCR), by adjusting an amount of nitrogen gas which is mixed with argon gas used for sputtering so as to set a temperature coefficient of resistance of the thin-film resistor substantially at zero. SOLUTION: In the method of forming a thin-film resistor, argon gas and nitrogen gas are controlled in amount of flow by a mass flow controller so as to have a predetermined mixed ratio, and the gases are filled into a sputtering device and are adjusted to a predetermined gas pressure. A predetermined patterning is performed on samples which are formed into films under respective sputtering conditions, so as to form an NiCr alloy thin-film resistor. And then, a temperature coefficient of resistance(TCR) of the thin-film resistor is computed by measuring a change in resistance value from -40 to 120 deg.C. The coefficient increases in a positive direction until a ratio of nitride gas reaches 10% relative to argon gas. When a ratio of nitride gas exceeds 10%, the coefficient increases in a negative direction. When the amount is about 20 to 30 cc, a TCR is set at zero.  Therefore, it is possible to control a TCR according to an amount of nitrogen gas mixed with argon gas.

Abstract: PROBLEM TO BE SOLVED: To extend the service life of a die and to improve the quality of a gear by cold-forging a temporary low tooth-form by the low tooth die and thereafter, forming a normal tooth-form by the clod-forging. SOLUTION: The lower end of a cylindrical shaped metallic material 20 is inserted into a hole 21A of the die 21 and pushed in from the direction of the arrow mark X, and the metallic material 20 is pressed with a punch to form a male tooth-form on the outer periphery of the material 20. The male tooth-form formed on the outer periphery of this material 20 corresponds to the tooth-form of the die 21, i.e., the normal tooth-form 27 and the low tooth- form 28. The temporary tooth-form is formed by the cold-forging with the low tooth 28 having the lower height by (h) than the normal full tooth height H. Thereafter, the normal tooth-form is formed by the cold-forging with the normal tooth-form 27 having the normal full tooth height H. In this case, the temporary low tooth-form and the normal tooth-form are formed in one process with one die 21.  Just after forming the temporary low tooth-form, the normal tooth-form is formed.

Abstract: PROBLEM TO BE SOLVED: To efficiently execute data communication with a server client, etc., in direct communication between PHS slave machines. SOLUTION: An identification message to identify a server, a client is transmitted in the case of a call based on an identification code from a connected information equipment by an identification message generating part 202.

Abstract: PROBLEM TO BE SOLVED: To continue an operation in a state where abnormal control is done when a D/A signal is not outputted normally owing to a broken signal line which connects a microcomputer and D/A output means disposed outside the microcomputer. SOLUTION: A D/A output control signal 4 with which an instrument operation control microcomputer 1 outputs a predetermined D/A signal is outputted to D/A output means 2 disposed outside the microcomputer. The D/A output means 2 disposed outside the microcomputer sends a D/A output check signal 6 from the D/A output control signal 4 to the instrument operation control microcomputer 1. The instrument operation control microcomputer 1 inputs the D/A output check signal 6, whereby if a predetermined signal is inputted, then D/A output is normally achieved. Further, if a non-predetermined signal is inputted, then D,/A output judgement means 5 judges that the D/A output is abnormal.
