Filed: 1984-07-16
Abstract: PURPOSE:To simplify the manufacturing process and contrive to improve the accuracy and reproducibility by a method wherein the part of lower concentration and that of higher concentration are formed in the same semiconductor region by varying the dosage of impurity ions. CONSTITUTION:An oxide film 102 is formed on a p type Si substrate 101. Successively, a single crystal Si layer 103 is grown and an oxide film 104 is formed thereon. Further, a poly Si gate 105 is formed on the film 104. Next, impurity ions 107 of As or the like are implanted by the use of the gate 105 as a mask, thus forming effective source-drain regions 108 and 109. Then, impurity ions are implanted by avoiding the neighborhood of the gate 106, resulting in the formation of source-drain regions 111 and 112 of high concentration. When ion implantation is thus finished, finally high-seat-resistant regions 108 and 109 and low- seat-resistant regions 111 and 112 are formed by heat treatment. In such a manner, the field intensity of a MIS type transistor can be inhibited and its micro fabrication can be attained without the need of a spacer and the like.

Title: Electrode forming method for tuning fork type crystal resonator
Inventor: NASU HIROSHI
IPC: H03H3/02
Filed: 1985-07-02
Abstract: PURPOSE:To obtain a resonator with a degree of design freedom and excellent electric characteristic even with ultra-miniaturization by using a vapor-deposition mask having a sort of a bridge part for a through-hole for forming an electrode at the inner side face of a leg of a turning fork for the purpose of vapor- deposition. CONSTITUTION:The hatched part of the vapor-deposition mask 7 covering the surface of a crystal chip 5 is the through hole part 72 and the other part is a metal-made mask 71 and a bridge P connects masks O and S. The vapor- deposition mask 8 installed at the rear face of the crystal chip has similar structure and the position of the bridge P is deviated relatively to the position of that of the mask 7. Since the through holes Q, R are provided to form the inner side face electrode of turning fork legs 51, 52, the shadow by the masking is minimized by deviating relatively the position of the bridge P thereby preventing the cut-off of the electrode. Since the downward size from the turning fork is increased, the degree of design freedom is increased.

Title: Rotation angle detecting equipment of rotary machine
Inventor: MATSUMOTO TADAICHI
IPC: G01D5/245
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To enable rotation angle data to be calculated when the voltage of a power source of an R/D converter calculating rotation angle data from a resolver output once decreases to be lower than a specified value and then has returned to the specified value. SOLUTION: An R/D(resolver/digital) converter 14 outputs an A-phase signal showing normal rotation of a rotary machine and a B-phase signal showing inverse rotation. The R/D converter 14 outputs data ϕ showing the rotation angle itself (absolute value). On the basis of the A-phase signal and the B-phase signal, a CPU 40 calculates a rotation angle as data Ψ, and controls the rotary machine on the basis of the data Ψ. After the voltage of a power source 38 for the R/D converter decreases lower than a specified value and then returns to a voltage higher than or equal to the specified value, the CPU reads the data ϕ of the absolute value of the rotation angle, resets the data as the initial value of the data Ψ.  After that, similarly to the normal case, the data Ψare calculated on the basis of the A-phase signal and the B-phase signal, and the rotary machine is controlled.

Title: Light output stabilizing circuit of semiconductor laser
Inventor: SHOJI NOBORU
IPC: H01S5/068
Filed: 1985-07-03
Abstract: PURPOSE:To facilitate the control, to simplify and to reduce the cost of a controller by supplying the output signal of a photoelectric converter as a control signal to the first and second drivers to stabilize the light output of the second semiconductor laser. CONSTITUTION:A Data input signal input to a terminal 1 is connected through a driver 2 with a semiconductor laser LD5 to output a light output 10, the prescribed control input signal of the mark rate input to a terminal 11 is connected through a driver 3 with an LD6, a light output 7 is input from a photoelectric converter 8 to a controller 9 to input the output signal to the drivers 2, 3. If the output 7 increases than the set value due to certain cause, the output level of the converter 8 varies, and the output signal to the controller 9 controls the driver 3 to reduce a driving current of the LD6. Since these factors are also acted similarly on the LD5, the output 10 also increases, but the driver 2 is similarly controlled by the output signal of the controller 9 to set the output 10 to the prescribed value. Thus, the output 10 is stabilized irrespective to the bit pattern of the data input signal.
