Title: Detection of interface in tank
Inventor: INOUE MIKIO
IPC: B01J19/00
Filed: 1986-09-24
Abstract: PURPOSE:To enable detection of interface such as liquid surface or bubble surface in a tank, by applying light into the tank passing through a sight glass on a side wall of the tank from several points arranged outside vertically to measure and collate power of reflected lights. CONSTITUTION:Light is projected into a tank 1 passing through a sight glass 2 provided on a side wall of the tank 1 from several positions 3A-3D arranged outside vertically and reflected lights are received at the positions 3A-3D of a light receiving section. Here, in probes 3 provided at the positions 3A-3D, light from a lamp 33 is sent to a light irradiating section 31 passing through an optical fiber 34 to be applied into the tank 1 passing through the sight glass 2 and reflected lights are caught with a light receiving section 32 from a liquid phase section 11, a bubble phase section 12 and a gaseous phase section 13. Then, the lights are sent to a light irradiation/analyzation unit 5 through an optical fiber 35, where the intensity of the reflected lights from the sections 11, 12 and 13 is measured to be collated. Thus, as there is large difference in the intensity between the reflected lights, a phase at a specified location in the tank 1 can be learned with the reception of reflected lights by collating them mutually or with previous measured values.

Title: Semiconductor logic circuit with improved active current source
Inventor: HIRAKATA NOBUYUKI
IPC: H03K19/0952
Filed: 1988-09-07
Abstract: PURPOSE:To surely perform a push-pull operation by stabilizing the potential of a common source terminal by decreasing the impedance of a circuit between the common source terminal of a current source FET at an output stage and a power source terminal in high frequency manner. CONSTITUTION:When a signal of (H) is inputted to input IN1 and a signal of (L) to input IN2 after inverting their phases mutually, a transistor Q1 is turned on, and a transistor Q2 is turned off. Thereby, a Q4 is turned off and a Q5 is turned on. And a Q7 is turned off, and the source potential of the Q5 is shifted by the potential drop of a Schottky barrier diode comprising a level shift element 22, then, an H signal can be obtained at output OUT2. Meanwhile, a Q6 is turned on, and an L signal can be obtained at output OUT1. Even when deviation is generated in the timing of the change of an impression signal on the input IN1 and IN2, a high frequency component of cycle equivalent to the deviation can be short-circuited via a capacitor C3, and the potential at the source terminals of the Q6 and Q7 can be stabilized.

Title: Motor-driven tractor
Inventor: OKURA AKIRA
IPC: G05D1/02
Filed: 1988-09-09
Abstract: PURPOSE:To prevent the collapse and the drop of loads by mounting a speed changing means which changes the traveling speed of a motor-driven tractor with lapse of the time and a control means which can change the braking torque at braking to the tractor at its start in a remote control mode. CONSTITUTION:A magnetic sensor 22 detects a magnetic tape 41 laid on the driving path of a motor-driven tractor 11 while this tractor is traveling. A front wheel 12 is steered by a servo motor 29 based on the signal received from the sensor 22, and the tractor 11 is guided along the tape 41. When the tractor 11 is switched to a remote control operation, a drive motor 14 is controlled by a speed changing means 50 containing a thyristor chopper 51 and a timer 52. Thus the traveling speed of the tractor 11 is gradually changed with lapse of the time. In a braking state the braking torque is gradullay increased by a braking means 61. Thus a smooth braking action is ensured to reduce the shocks for the tractor 11. In such a constitution, the tractor guiding method is simplified together with reduction of the cost. Furthermore, the driving layout is also easily changed.

IPC: A45B9/00
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To keep an umbrella handle which tends to be insanitary, clean and sanitary by coating the surface of the handle with a coating material including an antibacterial agent. SOLUTION: A handle 3 of an umbrella is coated with a synthetic resin sheet 11', a coating material including antibacterial agent. The synthetic resin sheet 11', when heated by hot water or hot air, is stuck fast to the handle 3. A name plate 13 fixed on the surface of the handle 3 is also coated with the synthetic resin sheet 11'. If the synthetic resin sheet 11' is almost transparent, the name plate 13 can be clearly seen through the sheet. The antibacterial agent included in the synthetic resin sheet 11' is to prevent propagation of bacteria in a polluted part if the surface of the synthetic resin sheet 11' is partly polluted with sweat. Therefore, the surface of the synthetic resin sheet 11' coating the handle 3 is sanitary, and a user can hold the handle without any worry about insanitation unless the synthetic resin sheet 11' is peeled off by force.

Title: Television reinforcing signal system
Inventor: KAGEYAMA MASAHIRO
IPC: H04N7/015
Filed: 1993-09-10
Abstract: PURPOSE:To obtain a television reinforcing signal system with less ghost disturbance than that of a conventional system by dividing a vertical time reinforcing signal into signal series of three phases or over, applying frequency multiplexing to them and sending the multiplexed signal while being multiplexed onto upper and lower non-picture portions. CONSTITUTION:A vertical time reinforcing signal of an interlace scanning form having 360 valid scanning lines per frame, for example (hereinafter a VT signal of 360i form) is divided into three phases signal series 1-3 in a frequency multiplex circuit 2 and they are frequency-multiplexed to obtain a signal of 120i form. In this case, the signal series 1 is multiplexed without modulation as a base band, and the signal series 2,3 are multiplexed through orthogonal amplitude modulation. Then the result is sent while being multiplexed on upper/lower non-picture part of 120i form. Since the frequency multiplex signal is not accompanied with compression of a time base, a ghost image of the VT signal is produced at the same position as that of a major signal even when ghost is produced in a transmission line. Thus, ghost disturbance almost the same degree as that of an existing receiver is obtained and the effect of ghost is reduced more than that of a conventional reinforcing signal system due to time division multiplexing.

Title: Thermal recording material
Inventor: OKADA AKINORI
IPC: B41M5/337
Filed: 1987-09-08
Abstract: PURPOSE:To obtain a thermal recording material having excellent heat response characteristics and image preservability, by incorporating a specified color developer, for developing a dye precursor into a color, and a specified compound. CONSTITUTION:A compound of formula I is incorporated as a color developer for developing a colorless or light-colored dye precursor by reacting therewith when being heated, and further a compound of formula II is incorporated. A thermal recording paper employing the compound I and the compound II in combination can achieve a marked enhancement of image preservability which can not be achieved by use of other bisphenolsulfone. The use of the compound I as a color developer can achieve a high sensitivity superior to that of a thermal recording paper using BPA, which has not been achievable. A preferable amount of each of the color developer and the compound of formula II is ordinarily at least 5wt.%, particularly 20-500wt.%, based on the dye precursor. Heat response characteristic is further enhanced by adding a heat-fusible substance having a melting point of 80-160 deg.C such as stearic acid amide and N-hydroxymethylstearic acid amide.
