Title: Display device
Inventor: JINNO MASASHI
IPC: G02F1/1339
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To prevent a driver incorporated in an LCD(liquid crystal display device) from becoming unable to operate owing to a peripheral edge seal material. SOLUTION: The seal material 3 passes over a drain driver consisting of a horizontal shift register 51 and a sampling part 62 and the edge line of the seal material 3 is made straight in the area above the horizontal shift register 61. Operation characteristics of a TFT(thin film transistor) element vary right below the seal material 3, so the operation characteristics are different from those of TFT elements outside the area of the seal material 3, but not different between stages, thereby preventing adverse influence on display.

Title: Color video signal processing circuit
Inventor: OKADA HIROSHI
IPC: H04N9/87
Filed: 1987-11-14
Abstract: PURPOSE:To easily obtain a proper color signal line sequence at an optional part in a section corresponding to a field period by holding the line sequence of a chrominance signal in a section corresponding to each field period in a proper state. CONSTITUTION:When a signal reproduction part 11 reproduces a PAL color video signal white a VTR is in variable speed playback operation mode, a chrominance signal C which forms a field-period corresponding section including a part Cm where proper read information can not be obtained appears at the 2nd output terminal 11b of A switch 13 is controlled according to the polarity of a detection output signal Bd obtained from a phase detection part 15. Consequently, the chrominance signal C is extracted before the border part between the part Cm and part Cn following it, but an R-Y axis inverted chrominance signal C* is extracted after the border. Thus, the chrominance signal having the proper line sequence is obtained.

Title: Flow rate detector
Inventor: KAWAHARA KAZUNARI
IPC: G01F1/20
Filed: 1986-12-03
Abstract: PURPOSE:To detect a flow rate over a wide range by providing a by-pass flow passage which increases the flow rate of fluid which flows to the outer periphery of the peripheral surface of a sphere as the flow rate increases. CONSTITUTION:The majority of fluid run in a main flow passage 8 after a circulating flow puts the sphere 3 in peripheral motion. At this time, a pressure difference is generated between the outer peripheral part of the by-pass flow passage 9 and the minimum-diameter part 10 of the main flow passage 8 and the fluid flows in the by-pass flow passage from the outer peripheral part to the minimum-diameter part 10 of the main flow passage 8. As the flow rate increases, the rate of the fluid flowing to the by-pass flow passage 9 increases and many lines of flow are generated even on the peripheral surface of the peripheral part 4 in addition to the the center part. Consequently, the rate of the number of rotations of the sphere 3 to the flow rate decreases, but the rate of a decrease in the peripheral diameter of the sphere is small, so a magnetic variation rate detected by a magnetic detecting element 7b does not decrease much, so that the flow rate detection rate is widened.

CONSTITUTION:An ion of a P-type impurity is implanted into the whole surface of a semiconductor substrate 1; a P-type impurity layer 2 is formed. Then, the semiconductor substrate 1 is coated with a photoresist 3; the photoresist 3 in a part used to form an N-well is removed by a photolithographic process and is patterned. Si is etched by making use of the patterned resist 3 as a mask by using an alkali-based etching liquid or by a dry etching operation until the P-type impurity layer 2 is removed. In addition, an ion of an N-type impurity is implanted by making use of the photoresist 3 as a mask; an N-type impurity layer 4 is formed. The individual impurity layers are diffused by a heat treatment; thereby a P-well 5 and an N-well 6 are formed.

Filed: 1986-12-03
Abstract: PURPOSE:To increase/decrease number of channels simply by adding a distribution/combination circuit to a microwave section of a radio equipment where a modulator/demodulator section and a microwave amplifier section are provided separately. CONSTITUTION:A transmission frequency of a required high frequency RF is obtained by applying plural stages of frequency conversion, and a combiner/ distributer H is provided to an input/output section of the RF stage of a radio transmitter-receiver receiving the RF and three kinds (#1, #2, #n) of IF sections are connected to the RF section.

Title: Device for discriminating weld abnormality in butt welding machine
Inventor: YAMAMOTO MASAYA
IPC: B23K11/02
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To enable welding quality to be surely controlled by discriminating weld abnormality in butt welding on the basis of an energizing current by an energizing current measuring part and of penetration by a penetration measuring part. SOLUTION: The device is equipped with an energizing current measuring part 6 for measuring a welding current that flows to each electrode, with a penetration measuring part 7 for measuring the penetration of a weld zone, and a discriminating part 8 for discriminating weld abnormality in butt welding based on these energizing current and the penetration. In measuring the penetration, a laser displacement gauge 71 is used for example. The discriminating part 8 is such that it compares the energizing current measured by that measuring part 6 with a prescribed current value preset internally and that it judges whether or not the energizing current value is the prescribed current value. If the former is less than the latter, it is judged as a welding defect, with the discrimination result outputted to the controller.  The controller stops butt welding on the basis of the discrimination result and outputs an alarm from an alarm unit.
