Title: Recording apparatus
Inventor: MURATA TAKAYUKI
IPC: B41J2/13
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To maintain recording quality high while coping with an increase in recording speed. SOLUTION: A cycle of encoder signals (Tcyc) is measured every time heat pulses for one recording operation cycle are impressed. A value (Tcyc÷8) obtained by dividing the measured value by a count of heat pulses (8) in the one recording operation cycle is set as a cycle (t1') of heat pulses of a next recording operation cycle in a register 72. The value is compared with a count value (P1) of clock pulses counted by a counter 73 which is started by a heat trigger generated on the basis of an input from the encoder. When the P becomes equal to t1', the value of the counter 73 is cleared to control so that the heat pulses are generated with the cycle of t1'.

Title: Speaker
Inventor: YAMAGISHI KIYOSHI
IPC: H04R7/20
Filed: 1989-12-29
Abstract: PURPOSE:To more optionally control the edge resonance of an oval diaphragm and to control frequency characteristics by differently setting up the gap between the outer diameter of the oscillation face of the oval diaphragm of an oval speaker and the inner diameter of an edge roll in accordance with the major diameter direction and minor diameter direction. CONSTITUTION:The gap 9 between the outer diameter of the oscillation face of the oval diaphragm 5 and the inner diameter of the edge roll 11 in the major diameter direction and the gap 10 between the outer diameter and the inner diameter in the minor diameter direction are respectively differently set up so that the gap 9 is set up as the minimum play required for the adhesion of the edge and the gap 10 is positively expanded. Thereby, edge resonation in the frequency based on a minor diameter wavelength can be increased without increasing the edge resonance in the frequency of the major diameter wavelength, and since the gap is concentrically formed on the position of the minor diameter, a dip effect based on the resonance can be increased. If the relation of the gaps in the major and minor diameter directions is reversed, the edge resonance on the frequency of the major diameter wavelength can be increased.

IPC: G01N21/77
Filed: 1993-11-30
Abstract: PURPOSE:To easily dispose a waste liquid by causing a carrier solution to pass through a resin tube after injecting a fixed amount of sample solution into the carrier solution and reducing nitric acid ions to nitrous acid ions by irradiating the carrier solution with ultraviolet rays, and then, measuring the absorbancy variation of the carrier solution. CONSTITUTION:A carrier solution 1 is fed at a fixed rate by means of a pump 3. A sample 4 is injected into the solution 1 which is fed at a fixed rate at regular time intervals from a sample injecting section 5 and the solution 1 is led to the resin tube 11 of an ultraviolet-ray irradiating reducing device 6. In the tube 11, the solution 1 is irradiated with ultraviolet rays emitted for a low-voltage mercury lamp, resulting in the reduction of nitric acid ions into nitrous acid ions. Then the solution 1 is led to a three-way joint 7 where the solution 1 joins a light emitting reagent solution 2 fed from the pump 3 at a fixed rate. The mixture is fed to a reaction coil 8 which accelerates the reaction between the solutions 1 and 2. A reaction product arrives at a detector 9 which continuously measures the absorbancy variation of the mixture. Thus the amount of nitric acid ions contained in the sample is detected.
