Title: Electron gun structure
Inventor: MIYAWAKI TOSHITSUGU
IPC: H01J29/50
Filed: 1983-09-09
Abstract: PURPOSE:To improve the effect of suppressing vertical haloes generated around the fluorescent screen by making the diameter of the electron beam hole larger than the shorter width of the horizontal slit. CONSTITUTION:The diameter (d1) of an electron beam hole 1b' is slightly larger than the longitudinal length (d2) of a horizontal slit 1a. After a lower hole 2 is formed in a plate material 1, coining is performed using both an over jig having almost the same shape as that of the horizontal slit 1a and an under jig having the shape of a flat section 1d to form the horizontal slit 1a. Next, after the flat section 1d is placed on the under jig, finishing piercing is performed with an over jig having almost the same dimension as the beam hole 1b' to form the beam hole 1b'. After that, the thus formed body is punched into the desired shape, thereby making an electrode 3.

Title: Oil pressure elevator device
Inventor: MIYAKE TATSUO
IPC: B66B1/26
Filed: 1991-06-11
Abstract: PURPOSE:To shorten time from an operation command to cage start-up in an oil pressure elevator having an opening/closing valve which is operated by opening/closing of a pilot circuit using a solenoid valve between an oil pressure pump and an oil pressure jack. CONSTITUTION:As an oil pressure pump 3 is started up by an electric motor 4 receiving an operation command, pressure in the first circuit 6a increases. Simultaneously, an energizing command for the first circuit 6a is issued to close an inflow pilot circuit 9a. Then, when the pressure detected by a pressure sensor on the first circuit 6a becomes equal to the pressure of the second circuit 6b, an opening/closing command for an opening/closing valve and an energizing command for the second solenoid valve 11 are issued. This makes the opening/ closing valve 5 open and a cage 2 to start up. This arrangement shortens the time required before from an operation command for the electric motor 4 to energizing the first solenoid valve 10.

IPC: G02F1/133
Filed: 1987-07-02
Abstract: PURPOSE:To maintain a bistable state and to obtain a perfect memory effect by incorporating a photoisomerization reactive material into at least either of oriented films on electrode surfaces. CONSTITUTION:This ferroelectric liquid crystal element consists of two sheets of substrates 1, 9 coated with the oriented films on the electrode surfaces and a ferroelectric liquid crystal 7 and is constituted by incorporating the photoisomerization reactive material into at least either of the oriented films 3, 4. The liquid crystal orienting capacity of the oriented films can, therefore, be changed by combining two sheets of the substrates 1, 9 after rubbing of the oriented films, then subjecting the oriented films to photoirradiation with the phase on the higher temp. side than a chiral SmC phase. The element does not receive the force to control the orientation bearing in the chiral SmC phase and the bistable state is maintained according to this method. The memory effect is thus easily obtd.

IPC: G09F9/37
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent peeling between a partition wall and a substrate and to maintain good display quality. SOLUTION: Parts 3a, 3b of a partition wall 3 are formed to surround charged migration particles 5 and a dispersion liquid 4 for migration so that the partition wall is disposed not only in the region between pixels (the region except the region represented by number 2 in the figure) but in the pixel region 2, and these parts 3a, 3b are adhered to the substrates 1a, 1b. Thereby, the adhesion area (adhesion strength) of the partition wall 3 with the substrate 1a and 1b is increased compared with a partition wall 3 disposed only in the region between pixels, and peeling between the partition wall 3 and the substrates 1a, 1b can be prevented. Thereby, the migration dispersion liquid 4 or charged migration particles 5 are inhibited from moving to other pixels 2, and the display density of each pixel 2 is made uniform to maintain good display quality.

Abstract: PURPOSE: To hardly bring about chipping by cutting only a piezoelectric plate without cutting electrode fingers at the time of cutting the piezoelectric plate. CONSTITUTION: Comb-shaped electrode fingers 13a to 13i and 14a to 14i are so arranged that they are inserted between each other, and electrode fingers 14a and 13i in both ends in the surface wave propagation direction out of these electrode fingers are formed so as to have λ/8 width when the wavelength of the excited surface wave is λ. The other electrode fingers 13a to 13h and 14b to 14i are formed with λ/4 width. The width of areas between adjacent electrode fingers is set to λ/4. A piezoelectric plate 11 is cut along broken lines D-D and E-E to form two end faces facing each other. It is cut along the broken line D-D in the area λ/8 outward from the outside edge of the electrode finger 14a and is cut along the and E-E to form two end faces facing each other. It is cut along the broken line E-E in the area λ/8 outward from the outside edge of the electrode finger 13i. Consequently, chipping is hardly brought about because electrode fingers 14a and 13i are not cut and only the piezoelectric plate 11 is cut at the time of cutting, and satisfactory resonance characteristic is obtained because the width of electrode fingers 14a and 13i is λ/8.

IPC: H02J9/06
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To rapidly set the output of an inner oscillator synchronous with the commercial power, when a commercial power is recovered from a power outage. SOLUTION: When a commercial power recovers from power outage, the phase shift of the output of an inner oscillator 21 with respect to the commercial power is detected by a phase shift detecting section 31. According to the detected phase shift, a value set in a registor 29 is changed, and then a value for a timer counter 27 to become a full count value is changed to change the pulse cycle of each full count. This pulse is counted by a step counter 23. Each time the step counter 23 counts a prescribed number of pulses, one cycle of oscillation of the inner oscillator 21 is determined. In other words, one cycle of oscillation is changed according to the phase shift, so that a shift in the oscillation frequency of the inner oscillator 21 is made small.
