Title: Filter of inverter-controlled bubble generating bath tub
Inventor: HARAGA HISATO
IPC: A47K3/00
Filed: 1989-06-17
Abstract: PURPOSE:To obtain the filter of a bubble generating bath by connecting the filter to a circulating pump to communicate with each other, and slowly starting and stopping a motor at the time of starting and ending filteration and cleaning to prevent outflow of a filter medium in the filter. CONSTITUTION:At the time of starting and ending filteration and cleaning, the rotational frequency of a pump driving motor 12 is controlled by an inverter E to operate a circulating pump P. When the bubble jet operation and the filteration driving operation are simultaneonsly conducted by the operation of the pump driving motor 12, at the time of starting and ending the drive of a filter 10, the slowly increasing rotational frequency is given to the motor 12 to slowly start up and stop the motor 12. At the time of starting and ending the drive of filteration, the circulating pump P is slowly started and stopped by the inverter E to let hot water for bath from the circulating pump P slowly flow in the filter 10, whereby flying-up of a filter medium 57 is avoided to prevent the filter medium by from flowing into a bath tub main body 1 or the circulating pump P.

Abstract: PURPOSE:To better contact of a core pipe and a formed body and to ensure soldering by making the inner end imaginary diameter at the time of forming of a formed body smaller than the outer diameter of the core pipe when winding the formed body from a tapelike material by a forming device around the core pipe. CONSTITUTION:A tapelike material 1 is wound around a pin 26 of a die rotating body 12 and its tip is clamped to a core pipe P. Pressing dies 20a, 20b are lowered successively to bend the tapelike material 1. The axis O1 of the core pipe P is slightly displaced from the axis O of a hollow shaft unified with the die rotating body 12 in the direction of thrusting of the pressing dies 20a, 20b. The amount of extrusion is so made that it comes nearly into contact with the displaced core pipe P. Consequently, the inner end of the formed body is on the inner end imaginary diameter (d) that makes a line O-P' connecting the hollow axis O and formed inner end P' a semicircle. This inner end imaginary diameter (d) is smaller than the outer diameter D of the core pipe P, and when the formed body is wound around the core pipe P, it is expanded by (D-d)/2, and contact with the core pipe P is improved.

IPC: F16F9/43
Filed: 1989-06-20
Abstract: PURPOSE: To keep the push-out force of a piston rod for a long time by providing a valve device with a valve automatically actuated depending on pressure, and connecting a pressure accumulator to a working chamber in the case of pressure in the working chamber dropping below the predetermined value. CONSTITUTION: A valve device has a valve 5 automatically actuated depending on pressure. This valve 5 connects a pressure accumulator 2 to a working chamber 1 in the case of pressure in the working chamber 1 dropping below the predetermined value and cuts off connection in a state of the predetermined pressure being attained in the working chamber 1. A valve element of the valve 5 actuated depending on pressure is loaded by the pressure in the working chamber 1 on one side and loaded by a spring member 4 on the other side. The push-out force of a piston rod can thus be kept constant for a long time.

Title: Hydrophobic inorganic filler
Inventor: ISHII TAKASHI
IPC: C09C3/12
Filed: 1993-05-24
Abstract: PURPOSE:To keep for a long time the initial flexibility of a product obtained when a powdered iron steel slag is used as a filler for an organic binder, especially an elastomer and to provide a treatment process therefor which can dispense with drying step. CONSTITUTION:An iron steel slag powder as a filler is surface-treated with a hydrophobic substance to make the powder difficultly accessible by water such as moisture and thereby to suppress the development of an alkali stimulus. This treatment is performed by directly premixing them together at room temperature or an elevated temperature. Examples of the hydrophobic substances include oils and waxes rich in paraffins or naphtenes, and sorbitan fatty acid esters. A silane coupling agent is particularly effective because its hydrophilic side combines with the slag to make it hydrophobic. An article filled with the surface-treated slag is prevented from causing hardening even when used in wet environments for a long time.

Title: Optical picture reader
Inventor: KAMATA MASAO
IPC: H04N1/04
Filed: 1984-07-26
Abstract: PURPOSE:To decrease the power consumption by controlling the lighting cycle so that the turn-on period of a light source overlaps partially the storing period of a CCD image pickup element and that the turn-off period of the light source overlap partially the reading period respectively. CONSTITUTION:A control part 13 produces a synchronizing signal CS to actuate a turn-on circuit 11 for a prescribed period of time. Thus a light source 2 is turned on for storage of data to an image pickup element 12. A read signal RS is delivered from the part 13 when a prescribed period of time passes from generation of the signal CS. Thus the stored data are read out of the element 12. Therefore it is required just to turn on the light source 2 by the signal CS just for a period requiring illumination.

Title: Controller for beam position of optical deflector
Inventor: MOCHIZUKI KENJI
IPC: G02B26/08
Filed: 1986-07-04
Abstract: PURPOSE:To simplify the guiding-in process of beams by arranging two polarizing plates so that two beams of two photodetectors are transmitted selectively. CONSTITUTION:The polarizing plates 20 and 21 are installed on beam incidence sides of the two photodetectors 3 and 4 while aligned with the polarizing directions of the beams. When the beams are guided to the photodetectors 3 and 4 at the time of power-on operation, signals from the photodetectors 3 and 4 to movable reflectors 5 and 6 are cut off firstly and the movable reflectors 5 and 6 are moved and switched with a servo signal where the photodetectors 3 and 4 detects the light. Thus, the polarizing plates 20 and 21 are so arranged that the two beams 1 and 2 to the photodetectors 3 and 4 are transmitted selectively, so the beam phases never affect each other and the guiding process of the beams is simplified.

CONSTITUTION:A die 10 is composed of following members: a recessed hole 2 of a resin sealing part which is slightly larger than the external shape of the resin sealing part that is to be mounted in a semiconductor device; a protrusion 1 having side face parts 3 which clamp the base of external leads 7 in cooperation with pads; a lead molding face block 6 where the protrusion 1 is placed on an upper face and each lead molding face 5a having a small angle with respect to top flat part of the protrusion 1 as well as each lead molding face 4a having a large angle are formed so that they may come into contact with each central lower edge of the side face parts 3. A punch 20 is equipped with lead molding faces 4b and 5b having the same angles as those of the lead molding faces 4a and 5a of the die 10. Differences in angles of two lead molding faces 4a and 5a are determined on the basis of empirical data of warp which develops at the resin sealing part.
