Title: Rotating speed control circuit for fan motor
Inventor: HAMAGUCHI MARIO
IPC: H02P27/02
Filed: 1986-01-07
Abstract: PURPOSE:To eliminate the regulation of a balance between phases by counting pulses of frequency responsive to a signal from a sensor from a zero-cross point by a counter in the predetermined number to create a time of nonconduction of a thyristor. CONSTITUTION:A clock pulse generator 31 generates a clock pulse R of a period responsive to the output of a thermistor 4 for detecting a temperature. This pulse R is counted by a modulo-n counter 30 set at the zero-cross point of an AC power source. A period from the zero-cross point to the time when the counted value of the counter 30 arrives at a set value is phase-controlled as a nonconducting phase angle for a fan motor. Thus, an error due to the difference of the phases is eliminated to be accurately controlled.

Title: Intake reed valve for two-cycle engine
Inventor: SAKATA KENJI
IPC: F02B33/30
Filed: 1979-01-12
Abstract: PURPOSE: To improve a charging efficiency with a decreased intake resistance, and simultaneously reduce an inertial mass following a vibrating motion, by making a thickness of the intake reed valve thinner as it goes to the free end.  
     CONSTITUTION: The construction, where a thickness of the reed valve is made thinner as it goes to the free end, can provide a more flexion, bigger area of passage cross section and less intake resistance than those as in case of a reed valve of signal thickness, resulting in an improvement of charging efficiency and fuel consumption rate. And a reduction of inertial mass, following the vibrating motion, can obtain a faster speed of opening and closing motion of the reed valve, and an improvement can be made for the action of discontinuous combustion caused by a lowering of charging efficiency arising from a timing delay when in an operation of rapid acceleration.

Title: Dial information transmission system
Inventor: KOBAYASHI TOSHIKATSU
IPC: H04Q3/54
Filed: 1979-01-16
Abstract: PURPOSE:To make dial transmission possible by making use of the acquisition of an originating register even in case of a mobile telephone switchboard, by using both a timer method and an oscillation tone detection circuit. CONSTITUTION:Controller CTL receives dial information from input 2 and stores it in a memory. Next, once an orginating register trunk is acquired by a general subscriber equipment exchange, a dial-tone receding dial tone is received, its output turns into high level logic and the output of gate G1 also becomes high in level, so that output Q of F/F will be at a high level. Simultaneously, timer TM is reset. Next, since the output of gate G2 and output A of CTL are both held at high levels, relay P operates to send dial information. Then, CTL receives the dial output from input 1 and when it agrees with dial information stored in the memory, output A becomes low in level to stop the transmission of dial information. If the 1st number of the dial information shows an outgoing connection, the general subscriber equipment exchange is actuated. If it shows intra-office dialing, the output of TM and the Q output of F/F are held at high levels.
