Title: Oil-cooled screw compressor
Inventor: MORISAWA YOSHITAKA
IPC: F04C18/16
Filed: 1990-09-21
Abstract: PURPOSE:To improve noise eliminating performance and to reduce size by delivering compressed gas to an oil separating recovery device through a vibration absorbing pipe through which a gas-liquid mixture phase is caused to flow as an air bubble flow from a compressor body. CONSTITUTION:A screw rotor 18 is rotatably contained in a rotor chamber 17 of a casing 16 having the one end opened to a compressor body 11 and the other opened to a delivery port 12. Gas sucked through a suction port 15 is compressed by means of a screw rotor 18 and is discharged through the delivery port 12 to a vibration absorbing pipe 13 together with lubricating oil injected in the rotor chamber 17 for the purpose of cooling. By means of a number of air bubbles generated in a gas-liquid mixture phase, pressure pulsation of the gas-liquid mixture phase is damped to reduce the generation of noise. Namely, pressure pulsation of delivery gas is decreased by means of the noise absorbing pipe 13, pressure pulsation in an air reservoir part 20 is decreased, and an amount of noise leaking to the outside of a machine is reduced. Further, delivery gas is separated away from oil by means of an oil separating element 22 and delivered through an outlet part 21. Meanwhile oil is dropped in an under-located oil reservoir part 19.

Title: Lead terminal
Inventor: KANI AKIRA
IPC: H01J5/46
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To improve terminal connection workability and stability of airtight sealing through easy manufacturing method by forming a metal pin which penetrates through a ceramic plate constituting an airtight container, so that the pin cross sectional area of at least one position at tip side position which is further to the tip than a ceramic boundary is made smaller than the cross section area of the boundary section. SOLUTION: The cross sectional area of a neck section 3 formed on the tip side near the root of a through pin 1 in the vertical direction constituting a lead terminal through a ceramic plate 2 is favorable to be set to 50-85% of the cross sectional area of a boundary plane with the ceramic plate 2. The stress generated in the pin connecting work is relaxed by the deformation of the neck section 3, and cracks rarely occur at the pin root portion of the ceramic plate 2. An inclined face 4 toward the center direction from the boundary portion with the ceramic plate 2 being preferably formed on the surface of the through portion of a through-pin 1, and this prevents the penetration of the crack at the pin root portion to the back side. This lead terminal is formed by a conventional technique, and the shape of the through-pin 1 can be devised to prevent airtight sealing defects with little burden.

Abstract: PROBLEM TO BE SOLVED: To solve a problem attended with long time recording and reproduction of a video image caused when generation of a visual environment is aimed by generating a moving picture from the prescribed number of sample images over a consecutive time of a control signal. SOLUTION: Data such as flowers, insects, animals, and expressions of human faces are stored for a short time in a sample image recording medium 1. An image signal memory 2 temporarily records a series of sample images extracted from the sample image recording medium 1. A control signal generating section 3 extracts a sample image with a designated number from the image signal memory 2 and transfers the sample image to a buffer memory 4. Then the sample image (signal) sequentially extracted in this way is outputted to an image display section 5, where a pseudo moving picture is displayed. This, a long time image can be generated from the sample image consisting of a series of shot-time frame image by using the control signal. Furthermore, the generated moving picture corresponds to an external signal.

Title: Driving force distribution controller for four-wheel drive vehicle
Inventor: SHIGETA RYOHEI
IPC: B60K17/348
Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a driving force distribution controller for a four-wheel drive vehicle that can improve running stability and steering feeling by virtue of fine control on the engaging force of a torque distributing clutch in accordance with running conditions. SOLUTION: A CPU computes in S14 a rotational speed difference ΔN between the input rotational speed N1 and output rotational speed N2 of a coupling, and vehicle acceleration α as well. If the rotational speed difference ΔN is positive or S16 is acceptable, and the acceleration α is smaller than a set value α1 or S18 is unacceptable, a tight mode map is referred to in S20. Acceleration α not smaller than the set value α1 or proving S18 acceptable causes the procedure to refer to an acceleration mode map in S22. A negative rotational speed difference ΔN proving S16 unacceptable selects a reverse mode map to refer to in S24.  The engaging force T that corresponds to the rotational speed difference ΔN is derived from each map, whereupon a control signal having the voltage value that corresponds to the derived engaging force T is output to the coupling in S26.
