IPC: F04C18/18
Filed: 1986-09-19
Abstract: PURPOSE:To make the pitch and level of discharge pulsation reducible, by dividing each vane of paired rotors into two parts in the axial direction, and partitioning off the interval with a partition plate, while shifting each rotational phase of these vanes on both sides of the partition plate to some extent mutu ally. CONSTITUTION:Two vanes of rotors 5 and 6 are constituted of divided vanes 5a, 5b, 6a and 6b halved in the turning shaft direction of these rotors 5 and 6, and a partition plate 7 supported by a casing 1 is set up between these divided vanes 5a, 5b and 6a, 6b. These vanes 5a, 6a and 5b, 6b engaged with one another are supported on a turning shaft so as to make each differ as far as 90 degrees in rotational phase, so that phase, where pulsating pressure of the gas discharged out of both sides of the partition plate 7 is varied, is shifted to some extent, and since variations in the pulsating pressure interfere with each other, the pitch and the level are halved.

Filed: 1989-08-25
Abstract: PURPOSE:To make locking and unlocking of a vessel easily by furnishing a lock mechanism which is composed of a detent piece and a lock member mating with detent piece of the device body at the bottom of a tumble lever. CONSTITUTION:A detent piece 28 for locking a tumble lever 25 in a specified down position is formed at the bottom of the tumble lever 25, and in correspondence thereto a lock member 29 is fixed to the device body. In the standby condition in material accommodation attitude, a vessel 3 is turned by hand counterclockwise, and when it reaches a specified tumble attitude, the detaining surface 28a of the tumble lever 25 attains a little below the tip of a boss 29c. When the hand is separated from the vessel 3 upon moving the tumble lever 25 in the C direction until the side 28b comes in confronting the boss 29c, the detaining surface 28a contacts the detention part 29b of the lock member 29, and at the same time, the side 28b contacts the boss 29c to maintain the tumble lever 25 in locked condition. To unlock, the vessel 3 is moved toward the material release attitude, which causes the tumble lever 25 to move with energization of a tensile spring 27, and the detaining surface 28a is put off from the detention part 29b. Now the vessel 3 is restituted to the standby attitude.

Filed: 1985-10-04
Abstract: PURPOSE:To attain a stable high frequency oscillation output by providing a resonance circuit between the emitter and base of a hot electron transistor (RHET) utilizing a resonance tunneling effect where a super lattice layer is formed between an emitter layer and a base layer. CONSTITUTION:A resonance circuit (tank circuit) RC is connected between the emitter and collector of an oscillation active element Q being the RHET and a bias is applied by using a bias power supply V1 to cause the resonance tunneling in the super lattice layer formed between the emitter layer and the base layer. The operating region of the oscillation active element Q in this state exists in the negative resistance region and the oscillation output is extracted from the collector side while oscillation is caused between the emitter and base. The resonance tunneling effect is maintained sufficiently even in the terra Herz zone and since the RHET is a 3-terminal element, the oscillation circuit and the output circuit are separated completely an a stable high frequency output is obtained.
