Title: Control circuit for intermittent dc motor
Inventor: TAKAHASHI HIROMICHI
IPC: H02P7/288
Filed: 1984-06-30
Abstract: PURPOSE:To reduce power consumption by detecting the presence or absence of a load applied to a motor by the increase or decrease of a motor current and automatically responding thereto. CONSTITUTION:When a power source is turned ON, a comparator 3 compares the set voltage of a variable resistor VR1 with a voltage VR proportional to a motor current IM to control a transistor 2, thereby idling a motor 1. When a load is applied to the motor 1 to increase the current IM, an increase detector 4 outputs an increase detection signal Sc to invert a flip-flop 6. Thus, a relay 8 is inverted, the set voltage of a variable resistor VRL is input to the comparator 3, and the current IM increases to the rated current. When the load applied to the motor 1 is disengaged to reduce the current IM, a decrease detector 5 outputs a decrease detection signal SD to invert the flip-flop 6, thereby inverting the relay 8.

Title: Semiconductor light emitter
Inventor: SATO KEIJI
IPC: H01S5/00
Filed: 1991-06-07
Abstract: PURPOSE:To prevent the intensity drop of a signal light even if the modulated signal light is taken out as a monitor light by integrating first and second electric field absorbing light modulators, which connect with each other and have the same composition and the same structure, at both light emitting end faces of a lambda/4 shift distributed-feedback type semiconductor laser. CONSTITUTION:The light generated in a semiconductor laser part enters a first light modulator and a second modulator. The electrode 13 in the first light modulator and the electrode 14 in the second light modulator are connected to the same modulation signal line. Thereby, the light modulation in the first light modulator and the light modulation in the second light modulator become the same, so the modulated signal lights emitted from each become the same, and it will do to use one as an essential signal light, and use the other as a monitor light. By doing it, this way, the intensity drop of the signal light becomes so little that it can practically neglected, and the intensity of a monitor light becomes enough large.

Title: Fluidic flowmeter
Inventor: NUKUI KAZUMITSU
IPC: G01F1/20
Filed: 1994-05-26
Abstract: PURPOSE:To decrease the effect of pressure fluctuation on the upstream side. CONSTITUTION:The gas, which is received through an inlet part 11 of a fluidic flowmeter, passes through a first gas flow path 14 and an opening part 16 and enters into a second gas flow path 15. The gas mainly passes through the second gas flow path 15 and reaches a nozzle 21. A part of the gas passes through a bypass flow path 30 and reaches the nozzle 21. The gases passing through two flow paths 15 and 30 join in the vicinity of the inlet part of the nozzle and enter into the nozzle 21. The distances of the second gas flow path 15 and the bypass flow path 30 are different to each other. Therefore, when the gases passing through two flow paths 15 and 30 join, the phases of the waves caused by the pressure fluctuation at the upstream side are different to each other. As a result, when the gasses through two flow paths 15 and 30 join, the waves of the pressure fluctuation are weakened.

Title: Lock-up control circuit of automatic transmission
Inventor: SUGANO KAZUHIKO
IPC: F16H61/06
Filed: 1986-06-12
Abstract: PURPOSE:To greatly reduce a shock at the time of gear change by fully opening the hydraulic pressure feeding circuit of a low and medium speed friction engaging element and fastening said friction engaging element, by means of a timing valve with a lock-up release pressure as a switchover pressure. CONSTITUTION:When gears are shifted from a high speed stage to a medium speed stage in order to further accelerate from a high vehicle speed condition, a fastening pressure is generated in the hydraulic pressure feeding circuit 26 of a low clutch 24. Since only an orifice 50c is being connected in a timing valve 50 in the high speed stage, the fastening of the low clutch 24 is delayed. On the other hand, the fastening pressure is introduced into a lock-up control valve 28 and, further, as a lock-up release pressure is introduced in it, the valve 28 releases a lock-up device 18, while feeding the lock-up release pressure to the timing valve 50. Thereby, a spool 50b is switched over against a spring 50a and a port 50f is connected to a port 50g rapidly feeding the fastening pressure to the low clutch 24, to change over to a medium stage. Thereby, a shock at the time of gear change can be greatly reduced.
