Filed: 1987-03-13
Abstract: PURPOSE:To obtain a weight detector which is superior in durability and shock resistance by transmitting the displacement of the rotary shaft of a motor in a support direction due to loading to a weight detecting means without contacting the rotary shaft, and realizing a shock absorbing function. CONSTITUTION:The load W is transmitted in the support direction through the rotary shaft 10 of the motor which rotates in synchronization with power source cycles to press a weight transmission member 7 on a weight detecting element through a leaf spring 17 supported by a metallic fixture 16.

IPC: F02P9/00
Filed: 1981-04-20
Abstract: PURPOSE:To prevent overrevolution of an engine effectively with a small number of part items, in an ignition device of the internal combustion engine for power of a portable tool, by utilizing a photocoupler when the device is controlled with voltage of timing to be controlled and reverse voltage. CONSTITUTION:A capacitor 14 is charged through a diode and resistor 11 to increase potential at a point C in a period when voltage across x-y of a primary winding 2 in an ignition coil 1 built in a magneto becomes positive at a point y. If voltage at a point x becomes positive, an electric charge of the capacitor 14 flows in a light emitting diode 12, and this light turns on a phototransistor 16, and voltage division ratio is changed by a divider resistor 7 to decrease applied voltage to a thyristor 5. As an electric discharge goes on, light is not emitted from the light emitting diode 12, and the thyristor 5 is turned on to perform ignition. Now if speed of an engine increases, higher reverse voltage is generated from the ignition coil 1, and potential of the capacitor 14 is also increased to extend a light emitting period, then a delay of ignition timing is increased to prevent overrevolution.

Title: D/a conversion circuit
Inventor: SAKINO TOSHIHIKO
IPC: H03M1/66
Filed: 1988-03-14
Abstract: PURPOSE:To prevent useless noise production by taking a hold start time as data blank period in case of sampling and holding an output subject to D/A conversion. CONSTITUTION:For example, an R1-ch data is fetched in a shift register in a D/A converter 2 by a clock signal (f) during its data period and the clock signal (f) is stopped for a period from a time t1 to T+TDELTAT. Thus, the fetched R1-ch data is stored as it is and D/A-converted at the falling time of a latch signal (g). The S/H signal (k) for R-ch rises and the sampling of R-ch is started and when a time T elapses from a time t3, the S/H signal (k) for R-ch descends and the sampled analog data is held. Since the hold start time is in the blank period of the data (a), useless noise is not caused due to the effect of a digital data.

Abstract: PURPOSE:To measure automatically the fundamental frequency of a signal to be measured which contains higher harmonics by providing a pulse converting circuit for the signal to be measured which consists of a differentiating circuit, an output pulse width control circuit for a one-shot multivibrator, etc. CONSTITUTION:The differentiating circuit 7 outputs a positive pulse when a binary-coded signal (b) outputted by a binary coding circuit 1 rises and the one-shot multivibrator 8 outputs a positive pulse (d) with depth determined by a control circuit 9 every time a pulse is inputted to its input (c). A reference frequency oscillation circuit 2 generates a reference frequency. A gate control circuit 4 holds the opening time of a gate circuit 5 constant with a reference clock which is frequency-divided by a frequency dividing circuit 3. When a reset signal (f) is inputted, the control circuit 9 begins to narrows down the output pulse width of the multivibrator 8 continuously from its maximum value and when the negative pulse is outputted, the current pulse is held to output a gate opening permission signal (g). The circuit 4 opens the gate 5 for a time determined by the reference frequency after the signal (g) is inputted, and pulses which are inputted within the time are counted 6.
