Abstract: PURPOSE:To allow intake control valves to be controlled to the target opening even in an internal combustion engine incapable of obtaining sufficient negative pressure in an intake passage. CONSTITUTION:A negative pressure accumulating tank 18 is connected to a surge tank 8 through a check valve 24 to accumulate negative pressure. A positive pressure accumulating tank 20 is connected to the surge tank 8 through a check valve 26 to accumulate the positive pressure of pressure pulsation. The rod 11a of an actuator moves upward in this drawing to close intake control valves 9. The negative pressure chamber lid of the actuator 11 is connected to the negative pressure accumulating tank 18 through a first change-over valve 21, and the positive pressure chamber 11e of the actuator 11 is connected to the positive pressure accumulating tank 20 through a second change-over valve 22.

Title: Structure for mounting drainage pot
Inventor: HONDA SATORU
IPC: E03C1/29
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To facilitate mounting works, and to improve mounting accuracy by forming a drainage pot in a shape tapered toward the bottom and fitting the drainage pot into an opening formed to a skin from an upper section. SOLUTION: The drainage pot 22 is composed of a bottomed external cylinder 35 tapered toward the bottom, an internal cylinder 36 formed to the bottom section of the external cylinder 35 and a cup 38 covering the internal cylinder 36. A sealing material 32 is pushed into the drain inlet 31 of a bench 12 from an upper section, the upper end of the sealing material 32 is formed in the same surface as the surface of the bench 12, the pot 22 is pushed into the sealing material 32 from an upper section, and the upper end of the external cylinder 35 is formed in the same surface as the surface of the bench 12 and the internal cylinder 36 is covered with the cup 38.  Water collected in a recessed section between the external cylinder 35 and the internal cylinder 36 seals the passage of a gas and prevents penetration into a chamber of the gas when the gas is flowed back from the drain hose 39 side. Mounting works are facilitated by installing the pot 22 from the upper section of the bench 22, and mounting accuracy can be improved by fitting the pot 22 into the drain inlet 31.

Title: Tv signal transmitting method, tv signal transmitter and tv signal transmitting system
Inventor: TARIKI MOTOI
IPC: H04N7/00
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a TV signal transmitting method, the TV signal transmitting device and the TV signal transmitting system in which a TV signal is transmitted in an excellent way even when the TV system of a transmitter side equipment differs from that of a receiver side equipment. SOLUTION: In the case of sending/receiving a TV signal between a TV signal transmitter 1 and a TV signal receiver 2, the type of the TV signal for transmission reception is informed to each other prior to the transmission of the TV signal. Thus, even when the TV system differs between the transmitter 1 and the receiver 2, since a TV signal system conversion section 101 of the TV signal transmitter 1 converts the TV signal system, the TV signal for transmission and reception is matched to send the TV signal in an excellent way.

Title: Automatic coupling method for parts and device therefor
Inventor: OMAE YOSHIRO
IPC: D05B73/00
Filed: 1994-03-24
Abstract: PURPOSE:To position a sewing arm and a sewing bed constituting a sewing- machine frame in a highly accurate manner, thereby enabling them as to be automatically coupled together. CONSTITUTION:At least a relative position between a sewing arm A and a sewing bed B automatically clamped in a state of putting mutual joining surfaces together is automatically measured and, after the sewing arm A is automatically corrected of its position on the basis of the measured value, a coupling bolt is automatically clamped tight and then at least the relative position between the sewing arm A and the sewing bed B unclamped is automatically remeasured. In this case, if the remeasured value is within the specified accuracy range, their coupling is over, and thus a sewing-machine frame is completed. In addition, if the remeasured value is out of the specified accuracy range, the sewing arm A and the sewing bed B are automatically reclamped, and the bolt is automatically loosened to some extent, and then those operations of clamp, measurement, position correction, bolt clamping, unclamping and remeasurement are repeated.

Title: Magnetic recording and reproducing device
Inventor: SATOU MASAHIRO
IPC: G11B15/10
Filed: 1982-04-01
Abstract: PURPOSE:To eliminate the noise due to scanning of a switch, by making an input system, where a voltage dividing ratio at resistances is switched by the switch, coincident with the number of switches in effective combinations of multiple depression. CONSTITUTION:When a switch PLAY of a contact 21 which is inputted as a signal (b) and a switch REC of a contact 23 which is inputted as a signal (c) are depressed simultaneously, then the signal (b) has a voltage generated by the voltage dividing ratio of resistances 12 and 13, and the signal (c) has a voltage generated by the voltage division ratio of resistances 11a and 12b. Since a microcomputer 1 monitors driving states of terminals O0-O2, the microcomputer 1 discriminates that contacts of switches REC and PLAY are turned on. If a switch ASPS of a contact 28 is turned on to input a signal (d) simultaneously with depression of said switches to perform the triple depression, the microcomputer 1 discriminates an effective combination of these three switches. Thus, three systems are made coincident with the number of effective combinations with which operations can be commanded by simultaneous multiple depression are prepared.

Title: Displacement detecting circuit for encoder
Inventor: IIJIMA KENZABURO
IPC: G01B21/00
Filed: 1986-03-12
Abstract: PURPOSE:To stabilize output data at any time by adding a delay flip-flop DFF to a circuit composed of a function generating ROM, a counter, and a comparator. CONSTITUTION:The DFF 40 is supplied with data phi and the U/D signal S of the comparator 23 and the data phi at an input terminal right before the signal S rises is latched and outputted as data phia. When the signal S is '1' in a specific period, a counter 24 counts up, the data phi increases, and the last value of the data phia. An object of detection is reduced greatly in speed and the signal S becomes '0'; and the counter 24 counts down a clock CK by one to decrease the value of the data phi by one or increase it by one if the object of detection has almost no movement. Consequently, the signal S becomes '0' and the counter 40 begins to count up. Subsequently, this operation is repeated up to the time when the object of inspection begins to move at a relatively high speed and the data phi oscillates within a specific range. Consequently, even if the counted value of the counter 24 oscillates within one count, the oscillation is absorbed by the DFF 40, whose output does not oscillate.
