IPC: A47L9/02
Filed: 1991-04-15
Abstract: PURPOSE:To prevent the reduction of dirt and dust combing up performance, the weak rotation of a rotary brush, and the stop of rotation by spirally and projectingly providing a line of flexible and independent tube-shaped bodies on a rotor in a suction room of the nozzle. CONSTITUTION:A rotary brush 4 consists of a rotor provided to rotate freely in the suction room and a pedestal 9 whose cross section made of flexible material fit in a dovetail groove 8 of the rotor 7 forms a inversed T shape. The two lines of dovetail grooves 8 are provided in spiral. At the outside of the pedestal 9, tube-shaped bodies 10 are provided projectingly at intervals. As the result, the rotary brush 4 is rotated and driven and the tube-shaped body 10 adjacent to the carpet impacts the carpet while being collapsed, and when it is separated from the carpet, dirt and dust are separated by the suction brought about by the recovery of the tube-shaped body 10. The tube-shaped body 10 is made of the independent flexible material and is free from the intertwining of long and narrow dirt and dust.

Filed: 1985-08-07
Abstract: PURPOSE:To make a device to be compact, by setting a seal member which can be broken or dissolved, on a narrow route between a rotary shaft and a casing, in a closed cycle turbo machine. CONSTITUTION:A shut-down seal 600 is set in a narrow route 610 between a turbine rotor 100 and a bearing housing 310. A holder 630 of this shut-down seal 600 is filled up with a seal member 620 which can be dissolved at a low temperature or broken by a weak force. When a rotary shaft 130 starts to rotation, the seal member 620 is broken or dissolved, and the shut-down seal is released. In this way, a space necessary for the shut-down seal can be made smaller, and the device can be made compact.

Title: Optical pickup device
Inventor: MAEDA IKUO
IPC: G11B7/135
Filed: 1992-06-09
Abstract: PURPOSE:To improve the efficiency of utilizing the exit light from a light source and to reduce optical parts. CONSTITUTION:The change in the intensity distribution of the reflected light from a magneto-optical disk 6 is taken out as a magneto-optical signal. The laser beam of the linearly polarized light from a light source is emitted and then, its optical path is separated by a polarization beam splitter 3 and a quarter-wave plate 4 to the light for irradiating the magneto-optical disk and the light reflected therefrom. As a result, the need for parts constituting an analyzer is eliminated. The light for irradiation and the reflected light are separated by a difference between the P-polarized light and the S-polarized light and, the loss of the optical quantity is therefore substantially eliminated.

IPC: B06B1/02
Filed: 1984-08-22
Abstract: PURPOSE:To prevent a collision between a reflected wave and a plane wave and to stabilize the internal pressure in a liquid chamber by joining successively an electrical vibrator, a nozzle plate, and a body for supporting the vibrator and the plate with a binder, and providing an oscillatory wave-absorbing body at the bottom surface part of a liquid chamber of the body. CONSTITUTION:An electrical vibrator 1 having electrode membranes 2a and 2b, a nozzle plate 3 having a nozzle hole 6, and a body 5 for supporting the vibrator and the plate are joined with binding layers 4a and 4b, and an absorbing body 10 consisting of a porous material is provided at the bottom surface of a liquid chamber 8 of the body 5. Under said conditions, when a liquid is filled into the liquid chamber 8 and a specified voltage is impressed from an oscillating circuit, the vibrating system of the nozzle plate 3 is oscillated by the diametral vibration of the electrical oscillator 3, and the vibration is converted into flexing vibration 2. Consequently, the nozzle plate 3 presses the liquid in the liquid chamber 10, and the liquid is atomized from the nozzle hole 6. At this time, a plane wave generated in the liquid is absorbed by the absorbing body 10 to control a reflected wave and the internal pressure of the liquid chamber 8 is stabilized.

Filed: 1986-07-24
Abstract: PURPOSE:To reduce a capacity of an air ventilation facility and further decrease the cost of operation by a method wherein an opening is formed at a wall or a floor or a ceiling forming a living room, a gas permeation film is fixed in the opening and at least a part of amount of ventilation can be ventilated through the gas permeation film independent of a mechanical ventilation facility. CONSTITUTION:An opening 7 is arranged at a desired position of a wall 2 of a living room 1, and a composite film 8 is fixed at the opening 7. The composite film 8 is a three-layered film in which ultraviolet rays shielding film 10 is adhered to an outer surface of the gas permeation film 9 and a non-combustible film 11 is adhered to an inner surface of the film. The composite film 8 is capable of passing air in response to a difference in air pressures of interior air in the living room and surrounding atmosphere. Since an amount of feeding air V1 is larger than an amount of discharging air V2, the interior of the living room 1 shows a positive pressure, the air passes through the composite film 8 and permeates toward the surrounding atmosphere and at the same time contaminated gas generated within the living room, for example, carbon dioxide or carbon monoxide is also discharged. When a feeding amount of an air feeding fan 4 is set to have a relation of V2<V1, the interior of the living room 1 shows a negative pressure, the surrounding atmosphere flows into the living room 1 through the composite film 8 to ensure a necessary amount of fresh air to.

Title: Printer
Inventor: TAKAHASHI TAKAHIDE
IPC: B41J29/38
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent very short slips from developing and collecting within a device by a method wherein a printing process is inevitably executed by the predetermined several number of dot lines even when a printing halt switch is depressed during the printing process and then the printing is stopped so as to cut off printed portion. SOLUTION: Even when a printing halt switch is depressed during a printing process, during the conveying of a machine glazed paper to a printing position after the receipt of a printing starting command, during the printout from a line head 10 by the predetermined dot lines or during the feeding of the machine glazed paper, the printing process does not be stopped until the predetermined length is attained. After the depression, printing is performed by every one dot line. At every one dot line printing, a CPU 21 judges whether a printing halt flag is set or not. When the switch 11 is depressed during the setting of the printing halt flag, the printing is stopped, the printed portion is cut off the machine glazed paper and discharged outside. Accordingly, no very short slip develops even when the switch 11 is depressed just after the start of printing.

IPC: G05D3/00
Filed: 1988-07-12
Abstract: PURPOSE: To obtain a fast operation speed by allowing reaction force required for a control supporting unit to approach a specific point to be applied with the force to a machine by the movement of a supporting body. CONSTITUTION: A computer 8 calculates reaction force generated by a control supporting unit 15 based upon the objective position of the supporting body 3 and stored mass data. A control signal from the computer 8 is applied to the unit 15 at a certain point of time and the unit 15 is constituted so as to generate required reaction force near a point of time when the same force as the reaction force with respect to its quantity and direction is applied to the machine 1 by the movement of the body 3. Thereby, force for arranging the machine 1 in accordance with the movement of the body 3 is instantaneously offset by the unit 15 simultaneously with the generation of the force. Thereby, the supporting body 3 is quickly accelerated and the stationary position of the machine 1 is maintained. Thus, an object 6 to be measured can be measured at a high speed corresponding to the object 6.

Abstract: PURPOSE:To unite a pressure piping with a valve mechanism to prevent gas leakage by providing a rod pressing a spool and a discharge valve against a closed position and urging the rod with an electromagnet. CONSTITUTION:When an electromagnet 68 is magnetized, a rod 74 is moved to the front side against elastic force of a spring 77. An end of a valve portion 75 closes an escape hole 72 of a spool 59.
