Inventor: EZAKA MUTSUO
IPC: H04M3/42
Filed: 1980-12-03
Abstract: PURPOSE:To increase the rate of call achievement at emergency call, by providing a means which stops callout through additional dialing without hook-on of a handset by the caller, at non-response of a called party, and a means calling out a subscriber designated by the additional dialing. CONSTITUTION:When a caller A hooks up a handset and dials the number of a called party B, a marker MKR is started to make relay line call connection for the sender.

Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide the negative feedback amplifier of a wide band at a low price by connecting the resistor element of a negative feedback circuit adjacently to the input part and output part of an amplification part. SOLUTION: The amplification part 21 comprising a semiconductor chip and the negative feedback circuit 22 connected between the input part IN and output part OUT of the amplification part 21 are arranged on the substrate of epoxy resin or the like and the negative feedback amplifier is constituted. Input side and output side resistors R1 and R2 comprising chip resistors decide the gain of the amplification part 21 and a capacitor C blocks the feedback of a DC component. It is to be used as a wide band negative feedback amplifier for a CATV for instance. In this case, the resistors R1 and R2 are connected adjacently to the input part IN and output part OUT of the amplification part 21.  Since the parasitic inductances L1 and L2 of a wiring pattern for forming negative feedback circuit wiring are present on a far side from the resistors R1 and R2 viewing from the input part IN and output part OUT of the amplification part 21, the change of impedance is small over a wide frequency range.

Title: Sample concentration instrument
Inventor: NAGAOKA TOSHIHARU
IPC: G01N33/48
Filed: 1994-07-22
Abstract: PURPOSE:To obtain a sample concentration instrument by which a sample can be concentrated simply and efficiently by a manual operation even in a very small gravitation space by a method wherein a dialytic film is attached to a bag made of a flexible substance so as to form a double structure and a shielding means which can divide the double structure into a dialytic-film mounted part and a moisture-absorbent sealed part in a nonusage state is provided. CONSTITUTION:When a sample is to be concentrated, pure water is drawn out by a syringe 9, a sample liquid 3 to be concentrated is injected into the inside of a dialytic film 2 by means the same syringe 9, a shielding means 8 such as a clip or the like is taken out, a moisture absorbent 7 is brought into contact with the outer surface of the film 2, and only moisture inside the film 2 is made to ooze by the moisture-absorbing effect of the moisture absorbent 7. Since a bag 1 is soft and flexible, the contact efficiency with the outer surface of the film 2 of the moisture absorbent 7 is increased when the bag is crumpled by hands, and the ooze of the moisture can be promoted. The film 2 does not permeate proteins and cells at the inside although many minute pores are contained. A liquid portion is permeated to the outside of the film due to a permeative phenomenon, and as a result, the sample liquid is concentrated. When the moisture absorbent is brought positively into contact with the outer surface of the film 2 and the film is crumpled by the hands, the concentration of the sample liquid can be quickened.

Filed: 1994-07-22
Abstract: PURPOSE:To suppress thermal deformation of a grid reflector of frequency re-use type and to make a weight light by adopting a fiber reinforced composite material for a skin material and transferring and forming only a grid pattern onto the skin. CONSTITUTION:A prepleg 1 made of a fiber reinforced composite material is laminated on a solid die 2 processed to be a shape of a reflector plane along a die face. A material with a high radio wave transmittivity is used for the prepleg 1 forming a skin member. Then a conductor grid 4 side is opposed to the prepleg 1 and adhered closely thereto, a flexible film 3 side is pressed and the entire assembly including the solid die 2 is heated and formed. When the film is exfoliated, the grid 4 is transposed onto the skin to form the skin member 5 of a curved face reflector having the grid. The adhesive strength of the grid 4 to the film 3 is properly weakened by setting a layer with a low adhesive strength by electroless plating is to conductor layers when they are formed on the surface of the film with plating and then the reflector of low thermal deformation is realized.

Title: Oil-immersed transformer
Inventor: MIYAO HIROSHI
IPC: H01F27/32
Filed: 1983-09-19
Abstract: PURPOSE:To inhibit the extension of streamer and enhance insulation strength for creep breakdown by providing protruded portions in the vertical direction to the equal potential line at the surface of insulation barrier in the winding side. CONSTITUTION:An insulation barrier 7 having the protruded portions is disposed in such a way as being in contact with the surface of the insulation barrier 3 in the side of a high potential winding 1. The protruded portion of insulation barrier 7 is almost vertical to the equal potential line 8 at the lower side of clamp ring end portion 5. In case the protrodued portion is provided to the insulation barrier 7, the streamer generated by the end portion of winding 4 and the end portion of clamp ring 5 reaches the insulation barrier 7, thereafter moves to the insulator 6 at the end portion, extending along the surface of insulation barrier 7 but extension of streamer is inhibited at the protruded portion. Thereby, electric field at the end portion of streamer of partial discharge generated when the lightening impulse voltage is applied can be weakened for the extension and insulation strength of creep can be enhanced.

Filed: 1980-12-03
Abstract: PURPOSE: To aim at miniaturizing a lockup clutch by providing, in the axial center portin of an input shaft, an oil passage communicating with a directly coupling type clutch controlling chamber, a drain passage and a check valve actuated by a control link coaxial with the input shaft.  
     CONSTITUTION: If a solenoid 12a of a directional control valve 12 is actuated to communicate a negative pressure chamber 82 in an actuator 80 with a negative pressure chamber 82 in an actuator 80 with a negative pressure section in an intake duct 13 when the speed ratio of a pump 1 to a turbine 2 becomes below a predetermine a value, a diaphragm 81 is deflected left. Then, a control link 65 is also moved left by means of an actuating member 83 so that a check valve 60 is opened for allowing an oil passage 61 to open to a drain passage 62. Therefore, hydraulic oil in a control chamber S flows into a mission casing 8 from the oil pasage 61 through the drain passage 62 so that pressure in the control chamber S is decreased. Piston 42 is moved outwaed due to the decrease in pressure, and a pressure plate 43 is shifted toward a front cover 1b, so that a clutch disc 41 is clamped, thereby the turbine 2 is directly coupled to the pump 1.
