Inventor: KASHIWAGI TORU
IPC: G02F1/1333
Filed: 1991-10-25
Abstract: PURPOSE:To smooth and uniformize the liq. crystal oriented film by applying a coating soln. contg. a polymer component on the surface of a base film to reduce the flowability of the coating film, placing the base on the surface of a supporting plate low in surface energy and heat-treating the base.

The film base is then placed on the surface of a supporting plate low in surface energy and heat-treated above the curing temp. of the prepolymer to cure the prepolymer, and a liq. crystal oriented film is formed. Namely, the coating film on the surface of the film base is dried prior to the heat treatment for curing or hardening to reduce its flowability and heat-treated, and hence the generation of ruggednesses on the film base is suppressed in heat treatment of the coating film reduced in flowability.

Title: Speaker circuit
Inventor: YAMANAKA SUSUMU
IPC: H04R3/04
Filed: 1990-10-17
Abstract: PURPOSE:To protect clipping of a signal by providing a speaker circuit with the function that when the level of a signal applied to the speaker exceeds a predetermined value, motional feedback operation is stopped. CONSTITUTION:As the level of a signal applied to speaker 7 increases, sound volume to be discharged by speaker 7 is getting larger and the level of the detecting signal obtained by a detecting resistor 8 also increases. Further, when the level of the output signal from main amplification circuit 6 increases and the output level of rectification circuit 19 constituting a level detecting circuit 15 exceeds a predetermined value, a switching transistor 20 is reversed to the conductive state and a signal channel 22 for a detecting signal to an operating amplifier is grounded, so there is no detecting signal to be input to the operating amplifier 12, thereby eliminating a detecting signal to be input to an operating amplifier 3 constituting a mixing circuit 2. Thereby, a regenerating signal to be input to an input terminal 1 is amplified, applied to speaker 7, and discharged without increasing the level of low band frequency.

Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To conduct vibration proof for a pane itself by providing a vibration proof instrument including a pair of permanent magnets formed like a plate to closely adhere to the pane, and plate-like metallic covers fixed to the paired permanent magnets to cover the permanent magnets. SOLUTION: Two vibration proof instruments 1 are disposed opposite to each other with a pane 4 interposed between them. The respective permanent magnets 2 are attracted to each other, whereby two vibration proof instruments 1 are fixed to the pane 4, thereby putting the pane 4 in the partitioned state by the vibration proof instruments 1. The length of the metallic cover 3 is set according to the vertical or horizontal dimension of the pane 4. For safety, a drop preventive hardware 6 is installed on an existing sash 5, and the upper surface 3a and the lower surface 3b of the metallic cover 3 are fixed by screws 7. Thus, when two vibration proof instruments 2, for example, are fixed to such a position as to halve the area of the pane 4 opposite to each other, the vibration proof instruments 1 function as a muntin, thereby partitioning the pane 4 into the areas as before.

Filed: 1989-10-28
Abstract: PURPOSE:To prevent a clearance from being generated, even when an interior finish material is mounted to a predetermined location of a fan case mounting side end part, by constituting the interior finish material of a fan case of high molecular compound with specific bending elastic modulus at 25 deg.C. CONSTITUTION:Inerior finish materials X, Y, constituted of a high molecular compound with bending elastic modulus of 2,500 to 7,500kgf/cm<2> at 25 deg.C, are prepared and mounted to a predetermined position in the inside of a fan case 5. As a result, the interior finish materials X, Y, having suitable hardness and flexibility, are prevented from generating a clearance between the interior finish materials X, Y and mounting locations thereof when the interior finish materials X, Y are mounted to the inside of the fan case 5 even for more or less bad accuracy in a side surface presenting a complicated shape having a protrusion in a fan case mounting side end part of fan frames 10, 11 in the inside of the fan case 5. Accordingly, no turbulence is generated in bypass air passing through in the fan case 5, and propulsive efficiency of an engine can be prevented from deteriorating.

Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To eliminate a permanent magnet and a magnetism detecting element for special use for positonal detection. SOLUTION: A permanent magnet 14 is magnetized in eight magnetic poles and a boundary 14a-14h between each two adjacent magnetic poles is slanted. The angle θ of one 14a of the boundaries is made different from the angle θ' of the other boundaries 14b-14h.

Title: Step type delay characteristic equalizing circuit
Inventor: HATTA SHINICHI
IPC: H03H7/01
Filed: 1985-12-12
Abstract: PURPOSE:To maintain linearity in spite of low power consumption and excess input by switching several kinds of fixed type delay equalizing circuits by switches. CONSTITUTION:The inclinations of delay characteristics in respective delay characteristic equalizing circuits 1-4 are slightly different each other and a bias is applied from a switch 14 arranged in front of a panel to pin diodes 5-12 of the delay characteristic equalizing circuits 1-4 through choke coils 17-20, 16 to connect the circuits 1-4. Consequently, only the delay characteristic equalizing circuit (any one of the circuits 1-4) specified by the switch 14 is driven to obtain necessary delay characteristics. Since the circuits 1-4 has no amplifier circuit, the circuits can be driven with low power consumption and linearity can be maintained also at the time of excess input.
