Title: Liquid crystal display device
Inventor: YAMADA JOJI
IPC: G09G3/36
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To improve display quality by providing a conversion circuit provided with a voltage detecting circuit and the initialization circuit generating the initialization signal of a delay circuit, to prevent a display screen from being displayed in a read screen shape. SOLUTION: A conversion circuit is provided with a clock circuit 62, a voltage detecting circuit 63 and an initialization circuit 64 for initializing a delay circuit 61 or the like. Then, the delay circuit 61 is kept in an initialized state during the period before the detection signal DT of a power source voltage VDD by the voltage detecting circuit 63 and an external DISP-OFF become both H levels and an internal DISP-OFF is kept in an inactive (an L level) state. Whilst the internal DISP-OFF is kept in this state, a scanning circuit and a signal circuit of this display device are kept in non-operating states.  Consequently, since the scanning circuit and the signal circuit of this display device are kept in non-operating states during the period before a bias voltage for driving liquid crystal rises to a stipulated voltage, the display screen is prevented from being displayed in the reed screen shape.

Title: Back light for liquid crystal display device
Inventor: SAKAKI YOSHINOBU
IPC: G02F1/13357
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To provide a high-luminance back light by reducing reflection at the time of the incidence of light on a light guide plate and improving the use efficiency of the light. SOLUTION: This back light adopts an edge light system and had fine unevenness 9 in an arcuate shape on the light incidence surface of the light guide plate 4. Consequently, the rate that the angle of incidence of light emitted by an axial light source 2 on the incidence surface of the light guide 4 becomes the normal direction where the least reflection is caused increases to reduce reflection caused on the flank of the light guide plate 4. Consequently, the incidence efficiency of the light is improved and the luminance is increased by 6 to 10% as compared with conventional luminance.

Title: Screw socket
Inventor: ONO TOMOYUKI
IPC: H01R33/22
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To prevent the lamp axis from being inclined against the line perpendicular to the fitting plane direction of a socket. SOLUTION: This screw socket is fixed with a screw receiving metal 2 at one position of a bottom face in the opening section 11a of a socket body 11 made of an insulator and opened on one face, and the screw socket is provided with a correcting means keeping the center axis of a lamp nearly perpendicular to the fitting plane direction when the lamp is screwed to the receiving metal 2.

Title: Metal mold
Inventor: KAWAMURA JUNYA
IPC: B22D17/22
Filed: 1987-12-28
Abstract: PURPOSE:To prevent a molding from cutting out or scorching by providing a gas passage of the shape that the holding accuracy of an abutment position of a core upon a core holder is not lost on the face where the core abuts on the holder or on faces of mutual abutment of the cores. CONSTITUTION:In a step of feeding resin from a gate 10 to a cavity 11, gas is discharged from a gas vent slot 18 formed at a parting line and an ejector pin 19, and discharged from a gas passage formed by the relief 32a of a core 32 and the through hole 33a of a slide core 33. Since the relief 32a is formed at the core 32 and partly formed, the relative positional accuracy due to the engagement of the core 33 with the core 32 is similarly obtained to the case that the relief 32a is not formed. That is, since the gas is discharged from the engaging part of the core 32 with the core 33, it can prevent the molding from scorching or cutting out.

Title: Method and device for detecting appearance and quality of formable rubber material
Inventor: TANABE TAKASHI
IPC: G01N33/44
Filed: 1988-12-28
Abstract: PURPOSE:To detect the appearance and quality of a foamable rubber material by measuring the foaming rate of the material. CONSTITUTION:The foamable rubber material of the same amt. as the volume of the cavity 5 of a lower mold 3 is charged into a material charging port 4 and a heating plate 9 is lowered. The foamable rubber material is pushed out into the cavity 5 from an injection port 7 when a pressurizing plug 10 is fitted into the port 4. The foamable rubber material is sufficiently heated by the temp. of a metallic mold 1 at the time when the material passes the hole 7. The foamable rubber material is completely packed into the cavity 5 when the plate 9 descends completely and is superposed on the upper mold 2. The foamable rubber material starts foaming as the internal temp. thereof is gradually raised by the temp. of the mold 1. The material bulges into a passage 6 part on progression of the foaming. The displacement of the foamable rubber material in the passage 6 is, therefore, detected as the foaming amt. as it is. The displacement of the foamable rubber material is measured and simultaneously the foaming rate is calculated at this time. The correspondingly better appearance and quality are obtd. as the foaming rate is higher.

Filed: 1989-12-25
Abstract: PURPOSE:To reduce heat generated, and to increase transmission force by operating hydraulic clutch arranged between the inner sleeve of a first rotary shaft an outer sleeve of a second rotary shaft by means of a pair of pistons so as to form a hydraulic pump to be operated through a difference between rotations of both rotary shafts and communicating the port of the hydraulic pump to a piston driving cylinder. CONSTITUTION:When the end part 2 of an input rotary shaft rotates, an inner sleeve 14 rotates, and pump gears 26 and 28 are rotates relatively to an inner sleeve 14 by means of a ring gear 30 and pinions 32, 34 arranged on the end of the inner sleeve 14. Consequently, pressure difference is produced between parts 36 and 38. Accordingly, one of pistons 22 and 24 advances, and inner and outer plate holders 18 and 20 are pressed, and the inner sleeve 14 is connected to an outer sleeve 8 for transmitting turning torque to the end part 4 of an output rotary shaft. A certain amount of hydraulic oil leaks from a high pressure side between the gears and a casing to a low pressure side. When the relative rotational speed between the input and output shafts is low, the hydraulic oil leaks slowly, and the clutch is not engaged. When the relative rotational speed is high, the clutch is engaged. Consequently, output rotational speed can be controlled.
