Title: Sink device
Inventor: YONEMURA MASAAKI
IPC: E03C1/18
Filed: 1991-04-22
Abstract: PURPOSE:To reduce noise caused by water, dropping in a sink tank 11 from a faucet, or washing work. CONSTITUTION:A damping material 15 is stuck from the back surface to a cabinet including vibration generating portions 16 (e.g. portions where water from a faucet drops and washing work is performed) of a sink tank 11. Moreover resonance in the cabinet is restrained by coating the cabinet with a moisture condensation preventive agent 19 composed of foam resin having a sound absorption effect. Consequently sticking the damping material 15 on the cabinet, including the vibration generation portion of the sink tank 11, causes more effective display of a damping effect, considerably reduces noise generated by a shower or washing work, and moreover makes sound to be a deep tone color. Furthermore a more excellent noise reduction effect can be displayed because resonance into the cabinet can be restrained by coating the cabinet with the foam resin having a sound absorption effect.

Title: Frame synchronization establishing device in digital multiplex radio system by octal phase modulation
Inventor: OGATA KATSUTOSHI
IPC: H04L27/22
Filed: 1992-04-10
Abstract: PURPOSE:To establish frame synchronization in all of octal phases by converting data demodulated in response to the locking phase when the frame synchronization is established by a frame synchronization circuit. CONSTITUTION:Digital signals Sig1-8 in a gray code demodulated in the digital multiplex radio system employing the octal phase modulation (8PSK) are converted into a natural code by a 1st gray code natural code conversion circuit 1 and outputted to an adder 2. Moreover, an alternate signal generating circuit 6 outputs a 0 or 1 signal for a period longer than a frame synchronization time to the adder 2 via a J-KFF circuit 5. Then, the output from the circuit 1 is added to a signal of 0 or 1 from the circuit 6 periodically and the sum is outputted to a 2nd natural code/gray code conversion circuit 3. When any of the locked phases in the demodulator is 0, pi/2,pi or 3pi/2, the frame synchronization is established.

Title: Erasable ink composition
Inventor: IIJIMA ZENSHIROU
IPC: C09D11/16
Filed: 1980-07-04
Abstract: PURPOSE: An erasable ink capable of being easily erased with hydrochloric acid, which is prepd. by compounding an acid dye with a chlorate.  
     CONSTITUTION: An acid dye is compounded with a chlorate. The chlroate to be used in a water-sol. salt of the formula MClO 3  (wherein M is a cation), which is a metal salt such as sodium, potassium, calcium or magnesium salt. The acid dye is one having an acid group such as a sulfonic or carboxyl group in the form of a sodium salt. It is advantageous to use hydrochloric acid as an acid when a letter or design drawn by use of the ink composition is erased. Namely in the case of the hydrochloric acid, a chlorate reacts with the acid to easily evolve chlorine dioxide, chlorine, etc., which decomposes and erases the dye. It is possible to clearly draw a design and letter again on the space from which a letter or design has been erased because hydrogen chloride in the hydrochloric acid is volatile.

Abstract: PURPOSE:To detect accurately the coordinate position, by laminating planar resistors forming belt-shaped electrode at both ends respectively via a pressure- sensitive rubber sheet. CONSTITUTION:A planar resistor 1 containing belt-shaped electrodes 1a and 1b in direction (x) and a flexible planar resistor 5 containing belt-shaped electrodes 5a and 5b in direction (y) are laminated to each other via a pressure-sensitive rubber sheet 7. A DC power supply 13 is connected to the electrodes 1a and 5a via a switch 12; while the earth is connected to the electrodes 1b and 5b via a switch 15. Furthermore a high input impedance 17 and an A/D converter 19 are connected to the electrodes 1b and 5b via a switch 16. When an optional point P on the resistor 1 is pressed with an input pen 2, the resistance is reduced at the pressed area of the sheet 7 to secure a conductive state between resistors 1 and 5. Then switches 12, 15 and 16 are first turned to contacts 12a, 15a and 16b respectively. Thus the (x) coordinates of the point P emerge at the output of the converter 19. Then the switches 12, 15 and 16 are turned to contacts 12b, 15b and 16a to obtain the (y) coordinates.

Abstract: PURPOSE:To prevent an oscillating phenomenon at a differential gear unit from occurring, by setting up a connecting rod so as to make a turning path, which a connecting rod connecting part in a casing for the differential gear unit describes, interfere with another turning path of a connecting rod tip end. CONSTITUTION:A casing 9 for a differential gear unit is supported by a subframe 2 via an elastic member.

Hereupon, each elastic bush is installed at both ends of this connecting rod 16 and each of them is pivotally attached to the casing 9 for the differential gear unit and the car body 1. And, the connecting rod 16 is attached thereto as tilted so as to cause its front part to become higher. In consequence, a turning path of a connecting point P of the connecting rod 16 in case of producing an oscillating phenomenon forms an interfering zone C with the turning path of a point P by rotation of the connecting rod 16, whereby rotation of the casing 9 toward the upper part is checked. Thus, the oscillating phenomenon is effectively prevented from occurring.

Title: Inner periphery edge for slicing
Inventor: MIZOGUCHI KAZUHIKO
IPC: B24D5/12
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To provide an inner periphery edge for slicing which can cut continuously by only an automatable table dressing, while dispensing with a hand dressing. SOLUTION: When asymmetrical chamfering is carried out on the tip both corners of a root metal inner periphery and the radius (r) of the tip end both corners of an abrasive grain layer is different like radius r1 and r2 respectively and the radius R of the tip both covers of the abrasive grain layer is different and the ratio of radius R1 , R2 is adjusted in a prescribed range, R of the tip both corners of the abrasive grain layer improves the discharge property of chips generated during slicing and reduces the block by the chips adhered to the abrasive grain layer.  As the inner periphery edge is always pushed during slicing from a corner with a big R value of the tip both corners to a corner with a small R value, the cutting resistance difference of front/back is offset and a stable slice is possible and by the bending and meandering of the inner periphery edge can be controlled by only a table dressing by a mechanical guide, a hand dressing required a worker's skill is dispensed with.
