Title: Screw compressor
Inventor: MITSUYOSHI KIYOTADA
IPC: F04C29/00
Filed: 1985-07-17
Abstract: PURPOSE:To relieve the pressure pulsation due to overcompression by providing the casing adjacent to the discharge port with grooves which communicate the enclosing space with the discharge port and further determining the cross-sectional area of each of these grooves so as to be enlarged gradually up to the start of discharge. CONSTITUTION:On the inner wall of the casing 3 adjacent to the discharge port 2 of a screw compressor, grooves 16, 16a which communicate the enclosing space 10 immediately before discharge with the discharge port 2 are formed. And, the total passage area of these V-grooves 16, 16a is determined so as to be enlarged gradually while the enclosing space 10 moves in the position where it communicates with the discharge port 2. Thus, the gas overcompressed in the enclosing space 10 is gradually discharged through V-grooves 16, 16a, and the pressure pulsation due to overcompression can be relieved.

Title: Exchange having authentication function
Inventor: OGUCHI NAOKI
IPC: H04L45/17
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To provide an exchange that authenticates propriety of connection in the case of setting a direct path between terminals with respect to the exchange that is installed in a communication network where a direct path is set between terminals. SOLUTION: In addition to an address on a conventional communication network to terminals contained in the exchange, an address on the communication network of another channel contained in another exchange is given to the terminals, a server registers the latter address and a call sent to a terminal reaches the exchange by using the registered address. That is, when a call reaches a channel 21, the exchange 10a allows a caller to send an address of a network layer and sends the address of the network layer to servers 4-1, 4-2 to confirm that the address of the caller on the communication network is registered.  In the case that the coincidence of the address of the caller on the communication network received at the arrival of the call with the address on the communication network is confirmed, the exchange connects to a terminal 3-1 being a connection destination and when the coincidence is not confirmed, the exchange excludes the call to be an illegal call.

IPC: G11B19/02
Filed: 1988-06-27
Abstract: PURPOSE:To prevent the erroneous sending of a ready signal to a host device by turning the ready signal off at the same time that a medium is released from a rotating means in a disk device which is constituted in such a manner that a head is also released from the medium at the same time that the medium is released. CONSTITUTION:A ready detecting part of the disk device is constitutive of a means 100 for detecting the insertion of the medium, a means 200 for detecting the normal rotation of a medium driving motor, a means 300 for detecting such a read output as lower than a prescribed level during reading and a ready detecting circuit 600. Then, the means 300 is not operated for detection when the read output is turned to be lower than the prescribed level during writing or seeking, and the circuit 600 is a means for inhibiting the ready signal from being sent out when the level is lowered even in the case of the normal rotation of the medium. By such constitution, when the medium is released from the rotating means even in the case of the on-state of the means 100 and 200, the means 300 is turned off, and the ready signal is also turned off, so as not to be sent to the host device.

Title: Parts feeder
Inventor: KANAI TAKESHI
IPC: B65G47/14
Filed: 1994-07-11
Abstract: PURPOSE:To quicken the parts feeding work by feeding compressed air intermittently into a parts containing chamber in order to introduce chip part into a shoot while agitating. CONSTITUTION:When a parts feeder 7 stops at the sucking position of a suction nozzle 13, a compressed air supply rod 36 is lowered by means of an elevating/ lowering rod 18 and communicated with a supply path 39. A solenoid valve 32 is then opened at a desired timing to feed the compressed air into supply holes 28, 29 while regulating the flow rate. The compressed air ejected through the supply hole 28 is moderated so that a chip part in a chamber (component containing chamber) 21 is not jammed at the inlet of a shoot 22 and then the part is shifted to the outlet of the shoot 22 by the compressed air fed through the supply hole 29. Subsequently, a mounting head, i.e., a suction nozzle 13, lowers to suck the chip part and transfers the chip component to a mounting station where the suction nozzle 13 lowers thus mounting the chip part on a board.

Title: Vibration absorbing type exhaust pipe joint
Inventor: NORIKAWA TANOMO
IPC: F16L27/12
Filed: 1995-06-02
Abstract: PURPOSE: To provide an exhaust pipe joint low in the noise level leaking outside, without needing to fit an inner blade inside a bellows. CONSTITUTION: A bellows 15 of three-layer structure with a ceramic cloth layer 22 sandwiched between an inner pipe 21 and an outer pipe 23 is used. The inner pipe 21 is strongly excited being directly exposed to engine noise, the pressure fluctuation of exhaust gas and acoustic wave, but the vibration of the inner pipe 21 is cut off by the ceramic cloth layer 22 so as not to be transmitted to the outer pipe 23, and the ceramic cloth layer 22 has damping function by the mutual friction of fibers so as to suppress noise offensive to the ear and high frequency vibration of about 1kHz. Since the heat insulating effect of the ceramic cloth layer accelerates the temperature rise of a catalytic converter disposed downstream, exhaust gas purifying performance is also improved.
