Title: Lead wire takeoff structure and gas sensor using it
Inventor: ISHIKAWA SATOSHI
IPC: G01N27/416
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To maintain sealability over a long period of time even under high temperature by compressing a cover constituent member partially formed of heat resistant flexible material such as fluororesin, in its laminated direction to hold lead wires and to seal between the opening internal wall of a case and the lead wires. SOLUTION: A cover body 17 fitted into a rear end opening of a diameter contracted part 54b of an outer cylinder member 54 comprises cylindrical cover constituent members 171, 172 concentrically arranged in a radial direction. The cover constituent member 171 is fitted holding lead wires 19-22 inside the outer cover constituent member 171. The temperature of the outer cylinder member 54 occasionally becomes as high as 260-300 deg.C. At least the outer cover constituent member 171 facing the high temperature of the diameter contracted part 54b is therefore formed of heat resistant flexible material mainly composed of polytetrafluoroethylene, to improve heat creep resistance.  Even if the cover constitutent member 171 becomes high in temperature, sealability can therefore be maintained over a long period of time among the rear end opening internal wall of the outer diameter contracted part 54b, the inner cover constituent member 172 and the lead wires 19-22.

Title: Developing device
Inventor: MOGI FUMIO
IPC: G03D3/13
Filed: 1990-04-24
Abstract: PURPOSE:To allow a leader and films to be nipped by respectively adequate nipping pressures and to be transported by providing a driving roller, a 1st roller and an energizing means as well as a 2nd roller and an energizing means. CONSTITUTION:The 1st roller 80 is corresponded only to the transporting path of the leader 48. Since this leader 48 is cramped between both of the 1st and 2nd rollers 82 and a transporting roller 68, the leader can be surely transported in a prescribed direction by the strong nipping force. The films do not exist between the 1st roller 80 and the transporting roller 68 upon passing of the rear end of the leader 48 and ending of the nipping. The films 42 are nipped only by the nipping pressure of the energizing force of the 2nd energizing means 92 and, therefore, the nipping pressure of the films weakens. The trouble that the films meander in the transporting direction thereof is obviated in this way and the films are adequately transported.

Title: Voice coil motor
Inventor: NAKANE NAOHIRO
IPC: G11B7/085
Filed: 1989-04-26
Abstract: PURPOSE:To obtain a voice coil motor which exhibits good control performance regardless of the position of an optical head by arranging a permanent magnet such that the flux density thereof increases gradually along the moving direction of the voice coil and varying the flux density of the magnetic field of the permanent magnet in the moving direction of the optical head. CONSTITUTION:Since the thickness of a wedge type permanent magnet 23 increases in the direction A', flux density thereof increases continuously in the direction A'. Even if current having constant magnitude is fed through a voice coil 8 in order to drive a voice coil motor, higher driving force functions onto the voice coil at the side A' than at the side A. Even if a flexible print cable loosens as an optical head 5 moves toward the side A' to increase the reaction, driving force of the voice coil motor increases correspondingly and thereby the position of the optical head 5 can be controlled accurately.

Title: Pressure generator
Inventor: INOMATA HITOSHI
IPC: F15B5/00
Filed: 1978-09-01
Abstract: PURPOSE: To obtain appropriate pressure with high accuracy by the simple constitution easily, continuously, and automatically.  
     CONSTITUTION: When the appropriate setting electric signal is given to the force motor 33 of the weighted mechanism 3, the force coil 331 is repulsed to rotate the force bar 31 around the supporting point to press the piston 2. By doing so, the piston 2 is pushed down in the cylinder 1 together with the flapper 42 mounted on the piston 2 to reduce the space with the nozzle 41. Therefore, the back pressure of the nozzle 41 which is amplified to increase the output pressure P through the control part 7 is hightened. Being thus constituted, the downward force of the piston 2 and the force motor 33 and the output pressure P are balanced, and the piston 2 stops floating above the cylinder 1 to maintain the output pressure P at the set pressure.

Filed: 1980-08-08
Abstract: PURPOSE:To facilitate the restarting of an engine and improve fuel efficiency, by providing a heat-insulated cooling liquid temperature retaining tank in a required position in a cooling liquid circulation passage and by utilizing cooling liquid of relatively high temperature, which has been stored in the tank, to restart the engine after stoppage. CONSTITUTION:During the ordinary operation of an engine 1, cooling liquid 3 absorbs the heat of the engine 1 through a water jacket 2 and is then conducted to a radiator 4 through a cooling liquid temperature retaining tank 11 coated with a heat insulator 12 and through a thermostat 7 and is thereafter returned to the water jacket 2 by a water pump 6. When the cooling liquid 3 makes a round at the restarting of the engine 1 after stoppage, the liquid 3 is cooled by the engine. For that reason, the thermostat 7 which acts in response to the prescribed temperature of the tank 11 shuts off a circulation passage 5 to the radiator 4 so that the cooling liquid 3 of relatively high temperature in the tank 11 is conducted to the water jacket 2 through a by-pass 8 and the heat of the liquid 3 is transferred to the engine 1 to accelerate its warming-up.

IPC: B60G17/015
Filed: 1988-04-30
Abstract: PURPOSE:To prevent an abrupt change in vehicle height and instability of control by setting the working pressures of fluid cylinders to an averaged value thereof when an abnormality occurs in an electric instruction system for a pressure control valve, after working fluid in the cylinders being blocked at a pressure at that time. CONSTITUTION:When an abnormality such as breakage of a wire or the like occurs in a supply path for control current 1, a poppet valve 68 in a pressure control valve 22FL is displaced so as to increase the orifice diameter of a communication hole 52a to its maximum value for maximizing the flow rate, resulting in abruptly dropping the pressure of a pilot chamber PR1 to a value below a minimum pressure P1, irrespective of the output pressure from an outlet port 52c. Accordingly, the pressure of a pilot chamber PR2 also drops to a value below the minimum pressure P1 so as to temporarily block working oil. Then, the communication between an inlet port 80j and an inlet/outlet port 80n is interrupted while the inlet/outlet port 80n is communicated with an outlet port 80o so that hydraulic cylinders are communicated together through an orifice 86. Accordingly, the pressures of the right and left cylinders are gradually made to be equal to each other. With this arrangement, it is possible to prevent an abrupt change in vehicle height and instability of control.
