Patent JP-H09274995-A (JP)
Title: Circuit device
Inventor: TAKEDA HITOSHI
IPC: H05B41/24
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To suppress generation of beat noise. SOLUTION: A modulation circuit 7-3 is provided in a control circuit 7. A drive frequency at the time of on/off-driving a field effect transistor Q1 is determined by an oscillation frequency of an oscillator OSC. That is, it is determined by a frequency of a signal waveform generated at a contact point Pa of a resistance RT with a capacitor CT. The oscillation frequency of the oscillator OSC is changed by the modulation circuit 7-3. For example, it is changed in the width of ±25kHz about the center value of 175kHz. A drive frequency in on/off driving of the field effect transistor Q1 is thus constantly changed in the range of 150kHz-200kHz. Because the drive frequency is not stabilized at a constant frequency, it is stationarily prevented from interfering with radio broadcasting waves, thereby generation of beat noise can be restricted.

Abstract: PURPOSE: To preferably close a poppet valve by providing a guide member in a a sliding hole of the valve and engaging an elastic sealing member with the guide member with a stopper to thereby exactly interpose the sealing member at the seat surface of the valve.  
     CONSTITUTION: A guide member 8 is inserted into the sliding hole 3 of a valve body 1 in a poppet valve. A tapered portion 10 is formed on the hole 9 of the guide member 8. Stopper portions 12, 13 are formed at both ends of the sealing member 1. Seat surface 7 and tapered surface 14 are formed on one side of the sealing member 11 with a bore 15 is perforated at the inside thereof. Then, the tapered portion 10 of the guide member 8 is coincident to the tapered surface 14 of the sealing member 11 to urge the sealing member 11 into the guide member 8. Then, the guide member 8 is engaged at both end surfaces thereof with the stopper portions 12 and 13, respectively. Even if the pressure fluid is accelerated when the poppet valve is operated, the sealing member 11 is engaged with the guide member 8 and not disengaged therefrom to thereby exactly sit the seat surface 7 on the valve seat 2 to thus preferably seal the poppet valve.

Title: Ferroelectric liquid crystal display device
Inventor: KAWAGISHI HIDEYUKI
IPC: G02F1/137
Filed: 1989-04-03
Abstract: PURPOSE:To suppress coloring in a light state by nearly aligning the transmission axis of the electric vector of a polarizer with the direction of the left mean molecule long axis of ferroelectric liquid crystal in left twist interface structure. CONSTITUTION:When a ferroelectric liquid crystal element 1 is viewed in the direction from the polarizer 4 as a polarizing plate close to a light source 5 to an analyzer A as a polarizing plate close to an observer 4, interface molecules of the ferroelectric liquid crystal 1 are twisted in a left rotating direction and thus oriented. When two mean molecule long axes 2 and 3 and a rubbing axis R are viewed in two bistable states of the orientation state so that the intersections of those axes are on the lower side, the transmission axis P of the electric vector of the polarizer P is almost aligned with the direction of the left mean molecule long axis 2 on the left side of the rubbing axis R between the mean molecule long axes. Consequently, the coloring of the whole panel is suppressed to obtain the ferroelectric liquid crystal display device of high display quality.

Title: Welding jig for long-sized material
Inventor: MIHASHI IWAO
IPC: B23K37/04
Filed: 1986-04-09
Abstract: PURPOSE:To obtain a welding jig which prevents the change of position of stationary clampers in the longitudinal direction of long-sized materials according to the turning of a turning base and can be commonly used for tack welding and normal welding by setting the turning centers of turning bases on the long- sized materials. CONSTITUTION:The turning centers of the respective turning bases are made to coincide with the ends near the centers of the lower clampers 38 nearest the center which are supported to the turning bases. A semi-processed good is, therefore, smoothly curved without the generation of a vertical step between the top surface of the lower clampers 38 nearest the center and the top surface of the lower clampers 38 supported to a stationary supporting base 60 and a cross moving base 90. The positions of the lower clampers 38 and side clampers 44 supported to the turning bases do not change substantially in the longitudinal direction of the semi-processed good according to the turning of the turning bases. A slip is, therefore, hardly generated between the clampers 38, 44 and the semi-processed good.

Abstract: PURPOSE:To prevent metal wirings from deforming by connecting metal wirings through a cutout with an electrode pad and internal leads, and supporting the metal wirings for connecting the internal leads with the pad by the cutout. CONSTITUTION:Internal leads 1 and an island 2 surrounded by the leads are integrally formed, and a semiconductor element 3 is bonded to the island 2 in the state of lead frames. When the electrode pad 7 of the element 3 and the lead 1 are connected therebetween by meal wirings 4, the wirings 4 are bonded through a cutout 6 formed at the internal leads. Accordingly, since the wirings 4 are supported at the end of the lead 1, its warpage is prevented to eliminate the contact with the element 3 and the island 2. The metal wirings are hardly deformed due to the vibration at transporting time and horizontal force of pressure at resin sealing time since supported laterally by the cutout 6, and the adjacent internal leads 1a and the metal wirings 4a are not contacted.
