Title: Tape printer
Inventor: UENO HIDEO
IPC: B41J3/36
Filed: 1992-04-30
Abstract: PURPOSE:To obtain a tape with a legible printing and a good appearance and to eliminate the need for an especially small character font for a lower cost by a method wherein when the difference in the number of dots between a memory means and a calculating means is within a predetermined range, dot pattern data is generated while character pattern areas are partially overlapped with each other. CONSTITUTION:With respect to dot pattern data developed on a developing buffer 34B, the number of dots in a tape width direction is calculated. The calculated dot number is compared with a printable number of dots for a tape of every width, which is retrieved based on tape width data stored in a tape width memory 34D and a dot table 32A of a ROM. If the dot number of the dot pattern data in a tape width direction is not more than the printable number of dots, the dot pattern data is judged to be printable. After the dot pattern data stored in the buffer 34B is transmitted to a printing buffer 34C, multi-line character printing is made on a film tape through a thermal head 11. At this time, two or more character lines are distributed uniformly in a tape width direction to be dot printed on said tape.

Title: Device for preventing expansion of outrigger of special vehicle
Inventor: MUTO MISAO
IPC: B66C23/78
Filed: 1988-06-09
Abstract: PURPOSE:To surely prevent the inadvertent expansion of an outrigger by feeding pressure oil from a steering pump to the contracting side oil passage of a double acting cylinder via a selector valve, a pressure reducing valve, and a check valve during the travel of a special vehicle. CONSTITUTION:During the travel of a special vehicle, if a PTO coupling 18 is separated, a changeover switch 42 is turned off to change over an electromagnetic selector valve 41 to an open side. Then, so long as the special vehicle is in a traveling posture, pressure oil from a normally-operated steering pump 21 is fed to a contracting side oil passage 10 via the branch passage 25B of a steering oil passage 25, an electromagnetic valve 41, a pressure reducing valve 40, and a check valve 39. The fed pressure oil acts on the contracting chambers 15B, 5B of a slide cylinder 15 and a jack cylinder 5 to keep the cylinder 15, 5 in a contracted condition. Hence, during the travel of the special vehicle, the inadvertent expansion of an outrigger can be prevented irrespective of the leakage or reduction in volume of the pressure oil, etc.

IPC: G06T7/00
Filed: 1989-06-02
Abstract: PURPOSE:To inspect a pattern to be inspected with high accuracy and in real time by correcting the address of a reference pattern which is previously stored based on the position deviation data and in accordance with the pattern to be inspected and judging the noncoincidence between the picture data on the pattern to be inspected and the reference pattern. CONSTITUTION:A position mark 1b put in accordance with a pattern 1a to be inspected is detected, and various position deviation data are calculated for the position of the detected mark 1b against the position of a reference mark set previously. Then the address of the reference pattern stored previously in accordance with the pattern 1a is corrected based on those calculated position deviation data. The reference pattern data is read out of a reference pattern setting part 18 based on the corrected address. Then the noncoincidence is judged between the reference pattern data and the picture data on a wiring pattern. The quality of the pattern 1a is judged from the decided discordance state. Thus it is possible to judge the quality of the patterns 1a fetched via a video camera 2 in real time and with high accuracy.

Title: Pulse input circuit
Inventor: KAWAHARA TSUKASA
IPC: H03K3/023
Filed: 1986-06-17
Abstract: PURPOSE:To improve the margin of a pulse amplitude against malfunction by setting a comparison voltage of a switch circuit with a prescribed potential from a bias voltage at an input terminal and switching the voltage in opposite direction to that of the bias voltage of the input terminal. CONSTITUTION:With a transistor (TR) 7 turned on, a bias voltage at a terminal 2 is VS-L, a TR 12 is turned on and a TR 13 is turned off. Thus, a TR 28 is turned on and a TR 16 is turned off, a bias voltage VR-H is given to a terminal 19 and a bias voltage VT-L is given to a terminal 34. With the TR 7 turned off conversely, the bias voltage at the terminal 2 is VS-H. With VS-H>VR-H, the TRs 13, 16 are turned on, the TRs 12, 28 are turned off and a bias voltage of VR-L and VT-H is given respectively to the terminals 19, 34 respectively. Even with VS-H<VR-H however, the TR 12 is turned on at the moment of VS-H>VR-H for the pulse amplitude inputted to the terminal 3. Thus, the accuracy of the switching level copes with the desired input.

Title: Power supplying method between camera accessories
Inventor: KAZUMI JIROU
IPC: H02J1/00
Filed: 1984-07-09
Abstract: PURPOSE:To supply electric power continuously for a specific time even after various operations are comleted at a side supplied with electric power by detecting the end of operations and holding a switch means forcibly on for the specific time after the detection. CONSTITUTION:The output of a one-chip microcomputer 15 is inverted from a high level to a low level after operation, and then a buffer 20 outputs a high- level signal for a specific time determined by a resistance 21 and a capacitor 22, so the output of an OR gate 23 is still the high-level signal and a transistor (TR)24 is still on. Therefore, the TR7 is on for the specific time. Then, the TR7 turns off when a TR24 turns off because a TR9 is still off, so that a data imprinting device 25 is not powered on by a source battery 3 any more. When the TR7 turns off, electric power is supplied from a back battery 16 through a diode 17 to maintain a power-down function state.

Title: Torque sensor
Inventor: HASE HIROYUKI
IPC: G01L3/10
Filed: 1986-06-18
Abstract: PURPOSE:To detect a torque accurately, by exciting a coil constantly as provided outside a soft magnetic alloy layer fastened spirally on a rotating shaft axially at a specified pitch to vary inductance of the coil. CONSTITUTION:An amorphous soft magnetic alloy 2 is wound on a rotating shaft 1 axially at a specified pitch. A coil 3 is wound on the outside thereof and provides an input to a differential detection circuit 4, where an output of an oscillation circuit 4a is kept at a constant peak with a peak control circuit 5 and is applied in series to the coil 3 and also to resistances 10 and 10 to detect an excitation current with a resistance 7. A potential difference is always constant between connection points 11 and 12 of the coils 3 and 3 and the resistances 10 and 10 respectively. As a torque is transmitted to the rotating shaft 1, the alloy 2 is distorted and a magnetic permeability changes to vary inductance of the coil 3, causing a change in the potential difference between the connection points 11 and 12. The change is detected with rectifier circuits 8 and 8 and a differential amplifier 9. This prevents a drop in the sensitivity as caused by a rise in the temperature, thereby enabling accurate detection of the torque.
