Abstract: PROBLEM TO BE SOLVED: To sweep reliably to the depths of piles of a carpet by blast from a communicating opening by providing a pipe having a hollow portion communicating with outside air in a dust collecting room, and providing more than one communicating opening communicating with the hollow portion and the dust collecting room on the wall of the pipe. SOLUTION: A pipe 7 is arranged in a dust collecting room 6 inside a suction device, a hollow portion 9 of the pipe communicates with outside air penetrating the outside covering of the suction device. The pipe 7 has communicating openings 10 communicating with outside air through a hole 8 of the suction device covering and communicating with the dust collecting room 6 on the surface. Such structure makes pressure inside the suction device lower than the pressure of outside air around the suction device and thereby allows outside air to enter from the hole 8 of the outer covering of the suction device, pass the hollow portion 9 of the pipe 7, and to be injected into the dust collecting room 6 from the communicating openings 10.  Thus cleaning work is carried out reliably by straightening the flow of suction air inside the dust collecting room 6 by jetting air and blowing off dust on a surface to be cleaned by a jetting air ejected to the surface to be cleaned effectively.

Inventor: EZAKI SANPEI
IPC: G02F1/135
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To obtain an image of high contrast without increasing the thickness of a photoreceptor layer by alternately depositing TiO2 layers and MgF2 layers and alternately depositing TiO2 layers and SiO2 layers to constitute a dielectric mirror layer. SOLUTION: In this optical writing-type spacial optical modulation element, the light beam 12 for writing enters through a first transparent substrate 1 to a photoreceptor layer 3, and the light beam 13 for reading which enters through a second transparent substrate 10 to an electro-optical effect layer 7 is modulated according to the light beam 12. A dielectric mirror 5 in this element is produced by alternately laminating TiO2 layers and MgF2 layers and alternately laminating TiO2 layers and SiO2 layers. By using MgF2 films having a large refractive index (1.38) instead of SiO2 films, almost same reflectance can be obtd. with a smaller number of layers. Since the number of layers is decreased, the impedance of the dielectric mirror layer 5 can be decreased.  Moreover, since the MgF2 film has higher specific resistance than SiO2 film, the surface resistance of the dielectric mirror layer 5 can be increased.

Title: Engine valve timing controlling device
Inventor: FUJIMOTO MISAO
IPC: F01L13/00
Filed: 1984-01-18
Abstract: PURPOSE:To reduce the vibration of an engine caused by variation in torque by adjusting the timing or the amount of lift of an intake valve so that the maximum combustion pressure is reduced in an operating area in which engine vibration greater than a set value is generated. CONSTITUTION:Signals which indicate the operating conditions of an engine such as engine speed, suction pipe negative pressure, throttle valve opening, etc., are inputted in a control unit 24 which controls the timing or the amount of lift of an intake valve 9. In case of an operating area in which engine vibration greater than a set value is generated, variation in torque is suppressed low by, e.g., controlling the amount of lift of the intake valve 9 to be smaller than that at the time of normal operation, to reduce charging efficiency and reducing the maximum combustion pressure, and the vibration of the engine is reduced. It is also effective to, (1) make the timing of closing valve delay, and (2) increase the period of time of overlapping. In particular, great effect can be obtained when these methods are applied to an engine which operates with the number of operating cylinders reduced.

Abstract: PURPOSE: To enable encoding and decoding with a small number of applied code tables by providing an information generation frequency counting part which finds occurrence probability and an adaptive code table generation part, and transmitting images in specific data units after variable length encoding using adaptive code tables. CONSTITUTION: A transmission-side information generation frequency counting part 101 counts the generation frequency of CBPCMs (combination information on the pattern of a color difference block and the mode of a mask block) of a frame which is currently encoded and finds the occurrence probability of each CBPCM from the generation frequency. The adaptive code table generation part 103 generates an optimum adaptive code table 104 from the occurrence probability of each CBPCM by using Hoffman method. A variable length encoding part 102 encodes the CBPCMs of a next frame by using the newly generated code table 104. A reception-side information generation frequency counting part 105, on the other hand, counts the generation frequency of CBPCMs to find the occurrence probability of each CBPCM.  An adaptive code table generation part 107 generates an optimum adaptive code table 108, which is used to decode the CBPCMs of the next frame.

Title: Magnetic head traveling device
Inventor: HASEGAWA TADASHI
IPC: G11B21/02
Filed: 1987-01-16
Abstract: PURPOSE:To reduce backlashes generated by the direction of rotation of a driving motor and to highly accurately position a magnetic head by providing two pieces of needles sandwiching a shaft to travel a mobile base, fixing the rear end part of one of the needles to the mobile base, and the rear end part of the other via a pressing spring. CONSTITUTION:The needle 9A positioned opposing to the needle 9 is brought into contact with the guide groove 8a of a shaft 8, and its rear end part is fixed on the projecting part 3d of the mobile base 3 via the pressing spring 12, also, this needle 9A is brought into contact with the guide groove 8a similarly with the needle 9. If the shaft 8 rotates in the direction of arrow A, the friction force between the groove 8a and the needle 9, and that between the groove 8a and the needle 9A are equal and in the opposite directions, therefore, no force acting in the direction of the normal of the shaft of a guide bar 6 occurs. Also, when the shaft 8 rotates in the direction of arrow B such as the case of the rotation in the direction of arrow A, no force that acts in the direction of the normal of the shaft of the bar 6 occurs, hence the magnetic head 2 can be stopped at one and the same place even when the mobile base 3 travels from the inner/outer peripheral direction of a storage medium.

Filed: 1990-01-17
Abstract: PURPOSE:To suppress the temperature of a coupling to below the allowed limit in any road surface state by providing a closing means for placing the coupling in the locked state in case of the temperature of the coupling exceeding the specified value, as well as providing a relief means for regulating torque. CONSTITUTION:When the temperature of a coupling is lower than the deformation temperature of a spring 48, a needle valve 45 moves to the right by oil flow from an orifice 43. On the other hand, when the temperature of the coupling exceeds the specified value, the spring 48 moves to the left to close the orifice 43 and enter into the locked state. When the oil pressure of the collecting chamber 41 exceeds the set pressure determined by the spring 48 and orifice diameter, the valve 45 moves to the right to reopen the orifice 43. The temperature of the coupling can be thereby suppressed to below the allowed limit in any road surface state, thereby suppressing to the level of not starting a tight corner braking phenomenon even if entering on a paved road in the locked state left from bad road running.
