Abstract: PROBLEM TO BE SOLVED: To provide a vehicle motion control device applying the optimum vehicle motion control in response to various vehicle travel states while maintaining the travel stability of a vehicle. SOLUTION: The actual behavior quantities δf, V detected by detecting sensors 4-10 are inputted to a target behavior quantity calculation section 12, and a travel state judgment section 12a judges the travel state based on the prescribed decision criterion. A selection section 12b selects the target characteristic information Kγ(V), Kβ(V), τ(V) corresponding to the travel state from a memory section 12c based on the judged result, applies them to a standard vehicle motion model 12d, and calculates the target yaw rate γdes and target vehicle body side slip angle βdes.

Title: Key telephone set
Inventor: SEKINE KATSUYUKI
IPC: H04M9/00
Filed: 1983-04-04
Abstract: PURPOSE:To simplify the response operation by giving the priority to the automatic response to an extension to provide simultaneously the incoming automatic response function for both a main wire and an extension freely. CONSTITUTION:When an incoming call comes from a main wire CO1, or CO2, a connecting section CN controls a selector SEL to transmit a main wire incoming tone to telephone sets STa, STb. On the other hand, when the telephone set STa makes a call, an extension incoming tone is transmitted from a signal generator SG2 to the telephone set STb. These incoming states are stored in a memory MEM at each telephone set. When the telephone set STb is in incoming state and hooks off, a discriminating section JUD discriminates the content of the memory MEM. When the call is an extension individual call, the telephone set STb is brought into an extension acquisition state regardless of the presence of incoming of the main wire. This applies also to the telephone set STa brought into the incoming state.

Title: Fluidic pump device
Inventor: MUROI AKIRA
IPC: F04C15/00
Filed: 1981-04-22
Abstract: PURPOSE:To remarkably decrease pulsation of suction and delivery power of a pump, by concentrically forming an internal peripheral surface of a housing with a rotor and arranging the displacement of the pump to a constant rate of change. CONSTITUTION:The displacement of a pump, contacted with across both ends of the first and second suction ports 32, 33, is always constant in no relation to revolution of a rotor 16, and the displacement of the pump, communicated to the first and second suction ports 32, 33, increases by a portion C increased with rotation of the rotor 16. Since the internal peripheral wall 13'a of a housing is concentrically formed with the rotor 16 in a portion between suction and delivery ports, the displacement is increased at constant proportion to rotary motion of the rotor 16, and a constant change rate of the displacement can remarkably decrease pulsation of suction and delivery power.

Abstract: PURPOSE: To provide a ureteral prosthesis usable for a long period of time, and capable of conserving its function without spoiling its comfortableness. CONSTITUTION: This ureteral prosthesis has a tubular frame formed by a spirally coiled stainless steel wire, and each spiral loop for this metallic wire is in contact with others adjacent thereto but permits the urine to flow from an inside to an outside or from the outside to the inside.

Then the ureteral prosthesis is inserted into a ureteral path in the straight state, and the hook shape of the both edge parts 11, 12 is recovered at the moment for the both edge parts to be disposed in a renal pelvis and a urinary bladder.  Further, at the inside, a metallic wire 3 having a small diameter is disposed so as to cross a spiral wire 2, and fixed to the both edge of the ureteral prosthesis by welding, so as to prevent the length of the ureteral prosthesis from being changed.

Title: Powder heat exchange device
Inventor: MOCHIZUKI AKIRA
IPC: F28C3/12
Filed: 1978-05-22
Abstract: PURPOSE: To reduce manufacturing and operating costs by driving a powder cooling and transport mechanism and a powder leakage discharging mechanism by the same driving mechanism.  
     CONSTITUTION: Powder fed into powder chamber 8 from throat 2 is transported to exit 4 while being stirred by ventilation plate 19. By means of crank 21, the rotational motion of driving device 10 causes plate 19 to make reciprocating motion corresponding to the motion of linking device 9. During this time, the powder is cooled by the cooling air supplied from air chamber 5. But, by this air, a part of the powder leaks through ventilation holes provided on plate 19 and piles in chamber 5. Scraper 11, which is operated by the reciprocating motion of linking device 9 is maintained vertical in the direction of exit A but moves freely in the returning direction. As a result, the piled powder is transported in the direction of exit and is discharged.

IPC: B60H1/32
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a hybrid drive type vehicular air-conditioner which can restrain the temperature of blow-out air from wising upon change-over from a mode in which a compressor is driven by an engine into a mode in which the compressor is driven by a motor, by lowering a desired post-evaporation temperature and an air volume of a blower just before the change-over. SOLUTION: After a desired post-evaporation temperature of an evaporator 9 is lowered below a steady-state value, and after a volume of blow-out air are reduced below a steady-state value just until a predetermined time elapses after the drive mode of a compressor 11 is changed over from a mode in which the compressor 11 is driven by an engine into a mode in which the compressor is driven by a motor, the drive mode of the compressor 11 is changed over from the engine drive mode into the motor drive mode, and accordingly, the degree of cooling of the evaporator 9 can be restrained from lowering, even after the engine 1 is stopped so that drive of the compressor 11 is temporarily stopped. Accordingly, the temperature of air blowing into a cabin can be restrained, thereby it is possible to restrain the cool feeling of an occupant from lowering.
