Title: Control signal transmission system
Inventor: KONDO HARUO
IPC: H04B7/26
Filed: 1990-08-03
Abstract: PURPOSE:To compress a guard time of a control signal more than that of a conventional system by adjusting a base station transmission timing with respect to a reference beam and controlling the guard time to be a prescribed time according to the difference between a distance of the reference beam and a satellite and a distance of other beam and the satellite. CONSTITUTION:A delay set for a control channel 7 arranged for a 1st beam 2a is selected to be twice an inter-beam propagation delay time difference  t13 with respect to a 3rd beam 2c and a delay set for a control channel 8 arranged for a 2nd beam 2b is selected to be twice an inter-beam propagation delay time difference  t23 with respect to a 3rd beam 2c. A base station 10 sends a signal 19 toward the 1st beam 2a with the delay of (frame length l7 + delay 22) with respect to a signal 18 sent to a 3rd beam. When the signals 18,19 from the base station 10 reach both mobile stations, the interval between both the signals is reduced by the inter-beam propagation delay time difference  t13 to be (frame length 17 + delay 16).

Inventor: OKUSA SHOICHI
IPC: H04N1/04
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a low pressure discharge lamp of a simple structure whose inconvenience generated in association with an abnormal temp. rise in filament electrodes in the final period of lifetime is precluded without use of any external means. SOLUTION: A stabilizing means 3 having a wall thickness of 0.3mm or below is furnished in a part of an air-tight vessel near a pair of filament electrodes 2 installed in translucent air-tight vessel 1. The stabilizing means should preferably be located in a part of a flared stem 1b near the filament electrodes, and this may be structured so that the tip of a thin tube 1b3 installed sealedly inside the flare 1b1 of the stem is opened and that the part of flare surrounded by the base end of the thin tube is given the specified wall thickness.  When the electron emitting substance attached to the filament electrode on the side where the stabilizing means is installed, has worn in the final period of lifetime, part of the filament electrodes gets a very high temp. in association with coming-in and going-out of electrons to cause softening of the stabilizing means, which results in protruding inward owing to the pressure difference between inside and outside and then a breakage which should stop the electric discharging, so that inconvenience such as melting of a base metal can be prevented.

Abstract: PURPOSE:To provide a control function for the sensitivity in flaw detection with a multi-channel flaw detector as well by controlling the sensitivity in flaw detection of the other probe for oblique angle disposed in the same probe head from the fluctuation in the height of the base echo by a vertical probe. CONSTITUTION:A vertical probe 4 generates an ultrasonic wave signal and transmits the reflection signal from an object 5 to be inspected to a signal transmission and reception section 3. The reflection signal is fed to a vertical control section 9, by which the sensitivity in vertical flaw detection is controlled so as to be proportional to the fluctuation in the height of the base echo. Only the base echo is detected in a detection section 6. The base echo is fed to a vertical processing section 7 where the wall thickness of the object 5 is decided. The result thereof is outputted from the section 7. The base echo is fed to a comparison part 8, which compares the same with a reference signal and outputs the fluctuation in the height of the base echo. The sensitivity in the flaw detection of the probe is controlled to a specified level in the section 9. On the other hand, a transmission signal is applied on a probe 12 for oblique angle from a signal transmission and reception section 11, which generates an ultrasonic wave signal. The sensitivity in the flaw detection of the signal reflected from a defect is similarly controlled so as to be proportional to the fluctuation in the height of the base echo from the probe 4 obtd. in the section 8, whereby the sensitivity in the flaw detection of the probe 12 is controlled always to the specified level.

Title: Scanning device and method for monitoring operation of scanning member
Inventor: HIROSUGI YOKO
IPC: B41J19/18
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To immediately, surely and accurately detect occurrence of an abnormal operation of a carriage or an abnormal operation of a printer causing the abnormal operation of the carriage and to prevent lowering of a throughput of the printing which may occur when detecting the abnormal operation, in a printer which prints by scanning of carriage. SOLUTION: This printer comprises a control system consisting of a CPU 1, a photointerrupter 11 and so on. A position (a logical position) of a carriage wherein the carriage is to be originally positioned is calculated and a position (a real position) thereof wherein the carriage is actually positioned is detected based on the input from the photointerrupter 11, the both of the positions are compared with each other, thereby judging the operating condition of the carriage. As a result, it is possible to detect the abnormal operation wherein the actual position of the carriage is not on the logical position. As an operation wherein the carriage is not returned to a detecting position of the photointerrupter 11 for detecting the abnormal operation, a throughput of the printing is not lowered.

Abstract: PURPOSE:To easily execute a non-interlace action by holding two transfer parts perpendicular to a one-column photosensing part, transferring simultaneously the respective fields of the odd number line and the even number line of signal charges and executing the accumulation of the signal charge. CONSTITUTION:The titled element is constituted of a photosensing part 11, an odd number field vertical transfer part 21, an even number field vertical transfer, part 22, a vertical transference switching part 23 and a horizontal transfer part 13. In accordance with incident light, the signal charge of the photosensing part 11 is moved to a vertical blanking period at a 1/30 second period and at the same time, the charges of the odd number line and the even number line are respectively moved to the transfer parts 21 and 22. The signal charges of lines alternately selected by the switching part 23 of these respective signal charges are sent to the transfer part 13. The signal charges are serially read out in one horizontal scanning period and are made into a one-frame video signal. For this reason, a vertical resolution is improved and further, even when a transference from the photosensing part to the vertical transfer part is executed every 1/30 seconds, after-images do not increase.

Abstract: PURPOSE: To reduce the amount of a cleaning liq. carried with a cleaned Si wafer held with a chuck mechanism when it is taken up from a cleaning bath by contacting the lower end of the wafer with a liq. removing pole and carrying it. CONSTITUTION: A substrate receiving table 5 has grooves at a pitch wide enough to hold about 50 Si wafers 2 and poles 6 protrudent from a cleaning liq. 7 circulating through a cleaning bath by a circulator. A chuck mechanism carries the wafer 2 on this bath, lowers it into the liq. 7, settles it on the table 5, lifts it and secures it there while the wafer is etched. This mechanism then lowers to chuck the wafer, takes it up, and finally slides to strike the lower end of the wafer against the top end of the pole 6, thereby reducing the amount of the liq. carried with the wafer.
