Title: Mold for molding lens
Inventor: YOSHIMURA FUMITAKA
IPC: C03B11/08
Filed: 1988-12-13
Abstract: PURPOSE:To prevent the generation of crackes in a lens in a cooling process after the press molding process of the lens by finishing the surfaces of molds at an excess glass material-relieving section disposed on the outer periphery of the molding surfaces in a surface precision enabling the smooth contraction movement of the molded lens material when cooled. CONSTITUTION:In a ring drum mold 4, a softened glass material 1 is put on a lower mold 3 and an upper mold 2 is subsequently moved downward to press the glass material 1. A lens having prescribed curved surfaces is thereby formed with the respective molding surfaces 2a and 3a of the upper and lower molds 2 and 3. In the mold for molding the lens, a relief section 5 for the excess 1a of the pressed glass material 1 is formed on the outer periphery of the molding surfaces 2a and 3a. A smooth surface processing is further applied to the upper and lower non-functional surface-processing surfaces 2b and 3b of the relief section 5. When the molded glass material 1 is cooled to wholly contract in the central direction of the mold, the excess 1a is smoothly moved from the relief section 5. Thereby, the generation of defects such as crackes in the molded lens is prevented in the cooling process.

Title: Servo signal correction circuit
Inventor: HACHI YASUO
IPC: G11B7/09
Filed: 1986-12-27
Abstract: PURPOSE:To stabilize a servo system, by correcting an offset at the boundary of a different area in a case where reproduction and recording are performed by following continuously a track consisting of areas of different signal modulation systems. CONSTITUTION:A monostable multivibrator 13 generates a sampling pulse having pulse width equivalent to a cycle higher than the frequency of a servo signal. The servo system does not follow the offset at the initial position of a header part, and the pulse is supplied to a sampling gate 14, and a tracking error signal from a differential computing element 6 is sampled, and after that, it is held by a capacitor C, then, an offset quantity to be corrected is obtained. A sampling gate 16 adds the voltage with opposite polarity of the offset quantity held only in the generation period of the offset except a sampling period outputted from a gate circuit 17, on the servo signal, and outputs a corrected offset. In such way, the servo system can be stabilized.

IPC: B41J2/045
Filed: 1989-12-01
Abstract: PURPOSE:To prevent chipping of a piezoelectric element and deforming of a vibrating plate in separating vibrators, and to stable the flying characteristics of an ink so as to make an excellent printing by providing an elastic plate having an external shape dimension smaller than that of the piezoelectric element. CONSTITUTION:A piezoelectric transducer has a plurality of vibrators 10 which are fixed on a base plate 15 at a same interval as ink discharging nozzles. The vibrators 10 have common electrodes 12 formed by PZT on one of surfaces of the piezoelectric elements 11 and pattern electrodes 13 on the other of surfaces of the piezoelectric elements 11, and elastic plates 14 are cemented on the pattern electrodes 13.

Title: Refrigerant distributor
Inventor: IMOTO TSUTOMU
IPC: F25B41/00
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To enable an accurate dividing of a plurality of refrigerant passages into a multiplicity of refrigerant passages with a heat exchanger which works as an evaporator of an air conditioner while preventing the occurrence of a large flow resistance at the time of combining the refrigerant flows, by a method wherein a refrigerant distributor is provided with a plurality of refrigerant inlets and outlets and they are combined into one refrigerant passage within a distributor. SOLUTION: In the case that a heat exchanger which is incorporated in a distributor is worked as an evaporator, the distributor has a refrigerant inlet 1 and a refrigerant outlet 2 and divides two refrigerant passages into four refrigerant passages. For example, two refrigerant passages are combined into one refrigerant passage and enters a body 3 of the distributor and four refrigerant passages exit from the body 3. The number of refrigerant passages at the inlet 1 and the outlet 2 may be arbitrary. Furthermore, the refrigerant passages may be produced by adhering two plates which are formed in a desired shape by a press for example, wherein a plurality of refrigerant passages are combined into one refrigerant passage and this passage is communicated with outlet-side refrigerant passages. Due to such a construction, as the refrigerant passages go downwardly, the refrigerant passages are increased in number so that an amount of refrigerant which passes through each refrigerant passage can be reduced thus restricting the pressure loss at a low level.

The outputs 105 and 106 are stored in the means 10 and 11 similarly for comparison in next-time scanning. The circuit 12 repeats the processes and the circuits 9 and 8 detects the phase and amplitude to decide whether the switch is ON or OFF from the directions of the phase shift and amplitude variation.
