Title: Fluorescent character display device
Inventor: KOJIMA SHINGO
IPC: G09G3/30
Filed: 1990-08-09
Abstract: PURPOSE:To reduce the using number of an expansive driver IC by connecting a driver IC for high withstand voltage which is connected with the anode of a fluorescent character display tube forming a quadruple matrix structure with a selector for controlling display data and a clock signal. CONSTITUTION:A selector circuit SELECT is connected with a data signal DATA or the clock signal out of the control signals of an anode driver IC of the fluorescent character display tube provided with the anode having the quadruple matrix structure so as to be connected with the driver IC 1. That means, the data signal DATA is connected with the input A of the selector SELECT, and the input B of the selector SELECT is grounded. And also, a selector signal SEL is connected with the select input S of the selector SELECT, and the output Y of the selector SELECT is connected with the DATA IN of the driver IC 1. And when the signal of the select input S is 'H', the data signal of the input A is transmitted to the output Y, on the other hand, when the signal of the select input S is 'L', the input B is transmitted to the output Y. Thus, the numbers of the unnecessary output circuit can be reduced.

Title: Digital video signal recording/reproducing device and digital data modulation method
Inventor: NOUZEN CHIYOUSAKU
IPC: H04N5/92
Filed: 1992-08-06
Abstract: PURPOSE:To improve the picture quality of the reproduced images by transmitting continuously two data of every other luminance signal and two adjacent data of the color difference signal respectively and modulating these data by making use of the correlation between the two continuous data. CONSTITUTION:The signals inputted through the terminals 10A-10C in a component form of a single luminance signal Y and two color difference signals PB and PR are converted by the A/D converters 11A-11C and divided by the S/P converters 12A-12C. Then the data are distributed to all channels by a channel distributor 13. Thus two samples of the luminance signals are distributed to the same channel every second sample, and the two cointinuous samples of the color difference signals are distributed to the same channel. The shuffling circuits 14A-14H rearrange the data. Then the error check marks are added by the error correction coders 15A-15H, and the data are converted by the modulator circuits 16A-16H. These converted data are recorded on a magnetic tape 18 by the magnetic recording heads 17A-17H.

Title: Prestress concrete steel material anchorage unit structure
Inventor: TAKAYAMA YOICHI
IPC: E02D5/80
Filed: 1993-08-24
Abstract: PURPOSE:To enhance a corrosion-proofing performance by painting a terminal of a PC material with synthetic resin and mounting a synthetic resin-made reticulate body to the outer periphery of the steel material by way of a spacer and protecting a coated film from being damaged. CONSTITUTION:An anchorage unit 3 of a PC steel material 1 is pained with synthetic resin while a spacer 2 is mounted to the outer periphery at an identical spacing. Then, a synthetic resin-made reticulate cylindrical body 4 is mounted to and fixed with the outer periphery of the spacer 2. In case when the anchorage unit 3 is processed and inserted into an excavated hole, the coated film is protected from damage since the cylindrical body 4 prevents the steel material from coming into direct contact with a ground surface or an excavated hole surface. Furthermore, even when an acute part of equipment, such as a boring machine hits against the cylindrical body 4, the cylindrical body 4 is deformed between the spaces 2, thereby preventing contact with the coated film. The anchorage unit 3 after grout is injected, is protected from cracks since the cylindrical body 4 acts as a reinforcing bar. This construction makes it possible to protect the coated film from damage during construction, and what is more, prevent the penetration of water from the cracks.

Title: Mass spectrometer
Inventor: ISHIHARA MORIO
IPC: H01J49/44
Filed: 1983-11-08
Abstract: PURPOSE:To enable the mass and/or energy of daughter ions to be correctly measured by using a time-of-flight mass spectrometer acting as the second mass spectrometer and providing a beam-chopping means which chops incident ions thereinto. CONSTITUTION:Daughere ions generated in a collision chamber 5 which is placed in the vicinity of the position of ion convergence by means of a double convergence mass spectrometer 2 and into which collision gas such as argon or the like is fed from the outside under a moderate pressure are introduced into a time-of- flight-type mass spectrometer 6. An accelerating power source 11 generates a pulse-type accelerating voltage which is applied to the place between the collision chamber 5 and the accelerating electrode. Since the deflection voltage sent from a power source 13 to the deflecting electrode 10 sychronizes with the above pulse-type accelerating voltage and becomes zero, the daughter ions can pass through an accelerating electrode 8 only during that period of zero and are developed in proportion to the mass thereof, while said ions reach an ion detector 7. A spectrum is obtained by detecting said daughter ions.

The casing 11 turns slowly, and its suction side is moved to the outside of the room after a given period of time. Air sucked from the outside of the room is passed through the casing 11 and the impeller 10, during which the air is given heat and moisture deprived previously to become the state of room air and the air is supplied to the room. The manufacture of the air ventilator can be simply manufactured with reduced number of processes and its cost is reduced because of using only one air blower.

Title: Semiconductor processing equipment
Inventor: OTAKI HIDEO
IPC: H01L21/31
Filed: 1990-08-08
Abstract: PURPOSE:To stabilize a film thickness through relaxation of field concentration by a method wherein a holder of line or face contact to support wafers is mounted at an electrode area. CONSTITUTION:Electrode plates 1 are fixed on the top of an electrode outer frame ceramic 2 with screws 3. The electrode plates 1 are mounted with ceramic spacers 4 at equal intervals. An electrode plate 1 is fitted with an arcuate holder 6 for supporting a wafer. When the holder 6 is thus mounted, contact with the holder to support a wafer 5 is supported by planes and lines. Application of high frequencies with this electrode plate 1 refuses field concentration because of a large contact with a wafer, prevents damage to wafers, and affords troubleless treatment without exceeding current limit. Further, using an electrode plate 1 improves contactedness with wafers and provides films of stability and uniformity in the case of deposition of a CVD film on a wafer.
