Title: Flat plate type piezoelectric transducer
Inventor: INOUE TOSHIHIDE
IPC: H04R17/00
Filed: 1986-10-13
Abstract: PURPOSE:To attain the large increment of a sound output and to obtain a transducer with a flatter frequency characteristic by converting the expansion and the contraction of a piezoe lectric film in a plane direction into the vibration of the alternately depressed and projecting shape in a height direction, and obtaining the sound output by making a skin member vibrate. CONSTITUTION:A driving part 1 is made by such a constitution that a polyvinylidene fluoride film is formed into a stripe, the sectional shape of which is the alternately depressed and projecting shape, such as a corrugated shape, and both the surfaces of it are laminated by a conductor foil so as to be an electrode part. The direction of the alternately depressed and projecting stripe is perpendicular to the direction of the elongation of the film, and the extension and the contraction of the elongation direction, the extension and the contraction of which are large, are converted into the change of a wave height. The skin members 2a, 2b are adhered at the top of the wave shape of the driving part 1 by using a conductive adhesive. The electrode part at the upper surface of the driving part 1 is electrically connected to the upper skin member 2a while the electrode part of the lower surface is connected to the lower skin member 2b, therefore, if an alternating signal is impressed between them, in the case of a positive signal, the piezoelectric film is elongated to the direction of the plane and the wave height comes high and the upper skin member 2a is driven forward, the the sound output is obtained by this back and forth movement.

Title: Protective structure
Inventor: OSAWA HIROSHI
IPC: E01F7/04

Abstract: PURPOSE: To reduce an impact force by the elastic deformation of a column in stone fall and earth collapse by supporting the road side of a roof or the track side of a railroad installed along an earth by the column, forming the column with a spring member, and fastening the roof to the earth side with a PC steel plate. CONSTITUTION: When an impact is given on a roof 3 from earth Y side by stone fall, earth collapse, snowslide, etc., a column 12 of a coiled spring 13 is compressed, and a tension is given to vertical fastening PC steel materials 9 and 9 and an anchor 10. Next, when the PC steel materials 9 and 9 and the anchor 10 are extended, the impact force is reduced, the roof 3 is rotated, and the coiled spring 13 of the column 12 serves as a cushion, whereby double damping effects can be obtained. Also, because the coiled spring 13 can be deformed in the horizontal direction, it is prevented for a stress to be concentrated into the column 12, roof 3, and the connection of the column 12 and a base 11 by stone falling due to deformation. Then, in recovery work, fallen stones, etc., are removed from the roof 3, and recovered by the coiled spring 13.  In addition, when an extension force is lowered by the extension of the steel materials 9 and 9 and the anchor 10, fixing devices 9A and 10D are loosened so as to give a tension force.

Title: Focus error signal generation circuit
Inventor: MURAKAMI TOSHIYA
IPC: G11B7/09
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To omit a labor necessary for adjusting work and to perform accurate adjustment by automatically adjust a focus bias based on the signal level of an RF signal. SOLUTION: A controller 20 fetches an RF signal as the output signal of an RF amplifier and A/D converts this RF signal. Subsequently, a peak value is detected and determination is made as to whether this detected peak value is maximum or not. If the detected peak value is not determined to be maximum, then a bias voltage is adjusted by switching-controlling the switches 27 to 32 of a bias voltage setting circuit 18 and then the foregoing operation is repeated until a peak value reaches a maximum level. After this rough adjustment, by monitoring the counting output of a jitter counting circuit, a bias voltage is fine-tuned.

Title: Photoelectric smoke sensor
Inventor: FUJIMURA TOSHIO
IPC: H03K17/78
Filed: 1993-09-30
Abstract: PURPOSE:To shorten an operation testing time by reducing the time constant of a sampling and holding circuit at the time of executing an operation test as compared with that for normal operation. CONSTITUTION:When a transistor(TR) switch S2 is closed at the time of executing an operation test, a resistance value between the switch S2 and the non- inverted input of an operational amplifier A2 to be the 2nd buffer circuit becomes parallel synthetic resistance value between both resistors R2, R5. Thereby a capacitor C2 is charged with electricity faster than normal operation. Thus when the TR switch S2 in the sampling and holding circuit 3 is turned to a closed state, the time constant of the circuit 3 can be reduced as compared with that of normal operation, reaction to a signal level can be accelerated and a smoke detecting speed can be improved. Consequently time required for an operation test can be shortened.

Filed: 1989-09-22
Abstract: PURPOSE:To eliminate wasteful movements of supply water, fuel, and air and attempt to improve the operation of a thermal electricity generation by the constitution that, when a target value of load varies, a subtractor sends the variation width of the difference of held load instruction signals and a target load value to a function generator and a preceding control signal is corrected. CONSTITUTION:A variation rate limiting device 5 holds its output for a specified time as soon as a target load value 15S varies. And, a subtractor 6 inputs a held load instruction signal 10S and the target load value 15 and inputs the variation width 16S of the difference between them to a function generator 4. The function generator 4 inputs a correction value 17S from 0.2 to 1.2 to a multiplier 3 according to input, and the correction value is multiplied by output signal of a differentiator 1 and the multiplication is inputted to each proportion calculator 2. With this arrangement, when the load variation width 16S is small, 0.2 is taken is a correction value 17S and it is multiplied to make each of preceding control signals 11S-13S small and when the width 16S is large, a corresponding large value is multiplied to make each of the preceding control signals 11S-13S large in order to make it possible to provide a preceding control signal output that is most suitable for any load variation pattern.

Title: Electrode structure for discharge lamp, its manufacture and discharge lamp using the electrode structure
Inventor: TAKEISHI MOTOI
IPC: H01J9/02
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To provide an electrode structure with high heat radiation effect, which can be easily manufactured at a low cost. SOLUTION: An electrode part 6 which has a larger diameter than an electrode stem 5 is formed at the end of the electrode stem 5 and a heat radiation part 12 is provided behind the electrode part 6 to encircle the electrode stem and integrally range to the electrode part. If a number of electrons collides with the electrode, excessive temperature rise is restrained because the larger- diameter electrode part 6 has great heat capacity and the heat radiation part 12 allows conduction heat to be radiated from the electrode part. The evaporation of electrode material is restrained, resulting in a longer life. The heat radiation part 12 integrally ranges to the electrode part 6 so that the heat of the electrode part 6 can be conducted directly to the heat radiation part 12 for heat radiation to restrain the excessive temperature rise of the electrode part 6.
