Title: Alarming device
Inventor: TERAJIMA KOJI
IPC: G08G1/09
Filed: 1990-04-04
Abstract: PURPOSE:To precisely perceive th existence of an approaching vehicle and the degree of danger with a driver and pedestrians by detecting the existence of the approaching vehicle and vehicle speed as information by a detector using a Doppler radar, exchanging the detected information mutually between respective alarming devices and executing alarm display in an alarm display part. CONSTITUTION:An electric wave emitted from an alarming device 1a is reflected on a vehicle and enters into a detector 2a. The reflected wave received by the detector 2a of which proceeding direction and vehicle speed are calculated by an arithmetic circuit with using a Doppler effect that frequency changes by the relative speed is transmitted to an alarming device 1b by an information transmitting/receiving device 4. In the alarming device 1b, alarm display is executed to an alarm display part 5b based on the transmitted information. The alarm display is executed to an alarm display part 5a also on the vehicle approaching to the alarming device 1b in the same way. Thus, respective drivers can perceive the existence of the approaching vehicle on an opposite lane and the degree of danger precisely in advance with confirming the alarm display part 5a or 5b.

Title: Propeller water wheel with guide cylinder
Inventor: ITOU NOBUO
IPC: F03B13/26
Filed: 1979-07-12
Abstract: PURPOSE: To attain the effective action of flowing water on runner blades by attaching a guide cylinder to the tip of the runner blades of a propeller water wheel.

Inventor: HISAMITSU SHINJI
IPC: G02F1/1337
Filed: 1989-04-07
Abstract: PURPOSE:To improve a display grade by subjecting picture element parts to a horizontal orientation treatment and subjecting the entire surface or a part of the surface exclusive of the picture element parts to a perpendicular orientation treatment. CONSTITUTION:A horizontally oriented film 3 consisting of polyimide, etc., is formed by an offset printing on an electrode substrate formed with patterns of transparent electrodes on a substrate 1 and is cured.

IPC: G06F11/26
Filed: 1990-04-03
Abstract: PURPOSE:To debug the hardware with high efficiency by analyzing the instruction that is read out of a peripheral circuit of a test subject as an instruction of a microprocessor MPU via an instruction decoder and then converting this analyzed instruction into the operation timing via an instruction timing converter. CONSTITUTION:The various data corresponding to an MPU mounted in a peripheral circuit of a test subject are written into a data table 24 from the host side via an instruction decoder 26. Then the decoder 26 reads the machine word of an instruction of the MPU out of the peripheral circuit of the test subject and decodes the machine word by reference to the instruction code decoding data on a data table 24. An instruction timing converter 28 sends the information converted from an instruction to a timing generator 30. Thus the generator 30 generates the timing based on the received information. In such a constitution, an instruction is read out of the peripheral circuit of the test subject and the same timing equal to that of an original MPU is secured based on the instruction. Then the hardware can be debugged with high efficiency.

IPC: B41J2/32
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a light-fixing apparatus and a color thermal printer which has a fixation speed increased without being made large in size. SOLUTION: A fixing device 19 for yellow which uses a light source of a flat plate such as a plasma display panel or the like, and a fixing device 20 for magenta which uses ultraviolet lamps 20a are incorporated in the color thermal printer. The fixing device 19 for yellow fixes a yellow heat-sensitive coloring layer by resting a color heat-sensitive recording paper 10 at a position opposite to an emission face for a resting fixation time of several seconds. The fixing device 20 for magenta fixes an entire area of a magenta heat- sensitive coloring layer by passing the color heat-sensitive recording paper 10 at a constant velocity to the emitting ultraviolet lamps 20a. Since the fixing device 19 for yellow will not change the fixation time even when the color heat-sensitive recording paper 10 is long, a print time can be shortened.
