Title: Grinder
Inventor: TAMAI TADASHI
IPC: B24B23/02
Filed: 1983-09-26
Abstract: PURPOSE:To enable grinding in the vicinity of wall, in a grinder for concrete, by arranging diamond chips on the outercircumference of rotary drum to form guides in front and rear and making the length of front guide shorter than 1/4 of the length of rear guide. CONSTITUTION:Upon turning on of a switch 7 to drive a motor 1 thus to rotate a rotary drum 3 and to mount the front and rear bases 8, 9 on a concrete plane, grinding is performed by diamond chips 4 arranged on the outercircumference of rotary drum 3 because of the step between the front guide 9 and the outercircumference of rotary drum 3, so the grinder is advanced to perform grinding along a plane. Since the dimension B of the front guide 9 is made shorter than 1/4 of the dimension A of the rear guide 8, it can grind the position near to an obstacle such as wall.

Title: Moving target tracking device
Inventor: IWAMA HISAO
IPC: G01S13/66
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To improve tracking continuity even if an erroneous detection occurs due to the remaining of the clutter of a fixed target by applying radar beams with two types of modulation waves to the target, calculating the approach speed of the target based on the observation distance of the target being detected by the reception signal of each modulation wave, and judging the traveling target and then performing a tracking processing. SOLUTION: A modulation wave transmitter 16 outputs two types of transmission waveforms to an antenna device 5 by time sharing according to the command of a beam control device 10. A reflected wave from the target of a transmitted wave is received by a receiver 6 and is outputted to first and second modulation wave detectors 12 and 13. After the detectors 12 and 13 perform demodulation for the target signal being obtained by first and second modulated waves, they perform detection, observe the distance and angle of the target, and output them to a target approach speed calculation device 14. The device 14 obtains the average values of the approach speed, distance, and angle and output them to an approach speed judging device 15. The judging device 15 judges whether the target is a traveling one or not from a clutter due to a fixed target, outputs it to a tracking filter device 8, and calculates a smoothing value and a prediction value.

Title: Controller of internal combustion engine
Inventor: IWANO HIROSHI
IPC: F01N3/24
Filed: 1993-07-16
Abstract: PURPOSE:To increase reduction performance of toxic component in exhaust air by operating external load at the time of idle operation immediately after cold start and increasing load and intake air flow. CONSTITUTION:An auxiliary air control valve 5 provided in an auxiliary air passage 4 which is provided by bypassing a throttle valve 3 is controlled by an engine speed control means 9. However, when it is detected that external load is not operating at the time of cold idle operation, external load is put in the operating condition forcedly by an external load operating means. Even if idle engine speed is increased to correspond to external load, the operation of external load is stopped when it is judged that target engine speed cannot be maintained due to the operation of external load by an idle engine speed maintenance possible judging means because external load is put in the operating condition forcedly. As a consequence, it becomes possible to maintain rise of engine speed which corresponds to increase of external load, and rise of exhaust air temperature becomes possible.

Title: Power supply circuit
Inventor: HENMI SHIYOUICHI
IPC: H02J1/00
Filed: 1980-12-15
Abstract: PURPOSE:To prevent the malfunction of a mu processor, by detecting the voltage when the power supply is cut off and suddenly dropping the voltage through simple constitution for a power supply circuit that supplies the power to a power supply terminal of the mu processor. CONSTITUTION:The power supply voltage +B transmitted through a resistance 14 is set a level lower than the prescribed voltage by the cutoff of a power supply switch 18. Thus the base current of a transisotr TR6 flows via a resistnce 3 to a Zener diode 12 whose voltage is lowered by the drop of the power supply voltage by the charging voltage of a capacitor 5. As a result, the collector current of the TR6 flows to the base of a TR9 through a resistance 7 to turn on the TR9. Accordingly, the voltage is dropped through a resistance 10 for a capacitor 15 and the base of a TR13 in a stabilizing circuit 17, and at the same time the voltage of a capactor 16 is also dropped through a diode 11. Thus the power supply of the mu processor drops suddenly.

Title: Method for bonding work with bumps
Inventor: SAKAI TADAHIKO
IPC: H01L21/60
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a bonding method which can facilitate repair works of a work having bumps soldered to pads of the work. SOLUTION: Bumps 19 of a bumped chip 18 is mounted on solder parts 15 on pads 12 of a substrate 11, and then heated. This causes alloy layers 20 defined by the solder parts 15 to appear on the bumps 19. An inspector conducts a test for continuity between the bumps 19 and pads 12 with use of a tester 19. In the case of a failure, the inspector puts a vibration applier 21 on the chip 18 to apply vibration thereto. This causes the weak alloy layers 20 to be destroyed by the vibration so that the chip 18 can be easily separated from the substrate 11. At the time of repairing it, it is unnecessary to heat the substrate 11 and chip 18 and thus such an electronic component as the chip 18 will not be thermally damaged.

Title: Intermediate transfer medium and image forming method using the same
Inventor: YAMADA HISAYOSHI
IPC: G03G15/10
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To have a sensible image to be efficiently transferred onto an intermediate transfer medium and to have the sensible image on the intermediate transfer medium efficiently retransferred onto a material to be transferred by specifying the swelling rate of a release layer to a liquid toner to a specific value. SOLUTION: The swelling rate of the release layer of the intermediate transfer medium provided with the release layer on the surface to the liquid toner is specified to 5 to 40%. The retransfer from the intermediate transfer medium onto the material to be transferred is inferior if the swelling rate is below 5%. The retransfer from the intermediate transfer medium to the material to be transferred is good and the glossiness of printed images is not good if the swelling rate exceeds 40%. The release layer may be formed of any materials, insofar as the materials satisfy the prescribed swelling rate to the liquid toner. The release layer consisting of a straight silicone resin is used more preferably in terms of durability, film formability and the glossiness of printed images.
