Title: Overload detector for hysteresis electric motor
Inventor: SASAKI KOUJI
IPC: H02K11/00
Filed: 1981-06-04
Abstract: PURPOSE:To obtain an overload detector of simple constitution which is adjusted more easily than an analog overload detector, by digitally discriminating between the overload operation and rated operation of a hysteresis motor by the lagging and leading of capacity. CONSTITUTION:A hysteresis motor (HM)1 is driven by an AC power source 3 through a switch 2. The input voltage V to the HM1 is insulated and level- converted by a transformer PT and then inputted to a phase shifter PS. The input current I to the HM1, on the other hand, is insulated and then detected by a current transformer CT, and level-converted and then converted into a voltage by a resistor R. The terminal voltage (i) of the resistor R and the output (v) from the phase shifter PS are inputted to zero-point detecting circuits Z1 and Z2 which detect the zero points of those signals and output pulses, thus generating the set and reset inputs to a flip-flop FF. The output of the FF is smoothed by an incomplete integrating circuit Imt to generate a signal LL. The signal LL is compared with a reference signal Ref by a comparator COM to obtain a contact signal (a). Thus, overloading is discriminated digitally.

Abstract: PROBLEM TO BE SOLVED: To perform exchange process of laser gas with no interruption or unstableness of laser oscillation and to allow continuous laser oscillation for an extended period. SOLUTION: A laser gas of appropriate partial pressure ratio is filled in a laser chamber at first and a laser gas pressure is set to a specified value. Then in an injection mode ml, halogen gas, rare gas, and buffer gas are gradually injected into the laser chamber for each specified laser oscillation pulse, and a power source voltage for laser excitation is gradually decreased according to injection amount, thus adjusted to a constant laser output. Then, when the power source voltage reaches a lower limit power source voltage Vmin, injection of gas is stopped, and switched to an exhaust mode wherein the laser gas in the laser chamber is gradually exhausted, for gradually raising the power source voltage for a constant laser output.  When the power source voltage reaches an upper limit power source voltage Vmax again, it is switched to the injection mode again, for repetition or injection mode and exhaust mode.

Title: Lock detecting circuit of phase-locked loop
Inventor: SATOU HIDETO
IPC: H03L7/10
Filed: 1983-05-18
Abstract: PURPOSE:To prevent delay of lock detection and stabilize operation against temperature variation by deciding on a lock state on the basis of data read in a shift register which receives the output of a PLL as input data. CONSTITUTION:One bit of PLL input data is read in and stored in the 8-bit shift register 12 consisting of software. A lock testing means 11 decides that a lock is made when the number of ''1'' in 8-bit data including seven bits which are already read is one or zero. When the decision on the lock is made, a sample clock switching means 15 performs switching from a high-speed clock 13 to a low-speed clock 14. When the lock is released, an alarm is outputted and then similar operation is repeated. Namely, the completely locked state of the PLL is detected in the start because of program control, and since no CR component is used as compared with a conventional circuit, temperature variation is reduced.
