Title: Reflector detection device
Inventor: YAMAMOTO TAKASHI
IPC: B60W30/00
Filed: 1991-11-01
Abstract: PURPOSE:To inhibit an alarm from being continuously sounded when a device is installed for detecting the distance to an object in front when an automobile approaches a road shoulder reflector embedded in a curved road at the time of travelling along a curve and giving the alarm when the distance is shorter than the safty distance between the automobiles. CONSTITUTION:When the automobile enters the curve and the road shoulder reflector is detected, the detected distance varies like a triangular wave, the alarm is sounded when the detected distance decreases and becomes shorter than the safty distance Dr between automobiles, the value stored in a memory when it is unmeasureable at a point (f,) the alarm is stoped when the distance increases rapidly at the point (g,) but the alarm is sounded again below Dr and the detected distance is stored at the point (h). By the detection of rapid increase at the point (g,) traveling distance from the point is measured and when the next rapid increase is detected at the point (i) before a prescribed value R is attained, it is discriminated that the object in front is the road shoulder reflector and the alarm is inhibited. Also, when no rapid increase of the detected distance is present even after traveling distance of R, the alarm is not inhibited.

Title: Printed circuit board for optical reader and method for mounting components onto the board
Inventor: UCHIDA WATARU
IPC: H04N1/19
Filed: 1989-12-01
Abstract: PURPOSE:To prevent the contrast of a picture from being deteriorated due to the reflection of a stray light invaded in the inside of the device onto components by coating components reflecting the light mounted on a printed circuit board with a dark black coating agent. CONSTITUTION:A jumper wire 2, an IC3, a radial component 4 are mounted on a printed circuit board 1 used for a handy scanner and a lead wire 3A for the IC3 and a lead wire 4A of the radial component 4 are soldered. Moreover, a mount hole 5 is formed near the components. The jumper wire 2, the IC3, and the lead wires 3A, 4A of the radial component 4 reflect a light and further reflect a stray light invaded in the inside of the handy scanner, then the reflected components are covered with a dark black coating agent 6 to prevent the reflection of the stray light and the mount of the components onto the board 1 is ensured by using the agent 6. In this case, when the main body of the IC3 and the radial component 4 does not reflect light, only the lead wires 3A, 4A may be coated by the dark black coating agent 6.

In this case, a doctor plate 2 where a thick-film layer excessively applied at the start of application is made to be thinner or removed, is freely rotatably installed on a coating liquid recovery pirn 3. This doctor plate 2 goes up and down by an air cylinder 11. The thick- film layer is expanded in the width direction to reduce the film thickness by turning the doctor plate 2 to the direction where the downstream side with respect to the advancing direction of the film 6 is squeezed, and the thick-film layer is removed by turning it to the reverse direction.

Inventor: SAIDA YUZO
IPC: C21C7/10
Filed: 1986-12-27
Abstract: PURPOSE:To prevent the absorption of nitrogen in Cr-contg. steel or the like during refining under reduced pressure by detecting the concn. of nitrogen in the atmospheric gas under reduced pressure from exhaust gas during refining and by introducing a gas other than nitrogen from the outside when the detected concn. exceeds a set limit. CONSTITUTION:During the refining of molten steel 7 in an atmosphere under reduced pressure, the concn. of nitrogen in exhaust gas exhausted from a duct 6 is detected with an exhaust gas analyzer 18. When the detected concn. of nitrogen exceeds a set limit, e.g., 40%, a gas other than nitrogen, e.g., an inert gas or oxygen is introduced into the atmosphere from the outside while exhaust is continued. Thus, the absorption of nitrogen in the molten steel 7 can be effectively prevented and low nitrogen or extra-low nitrogen molten steel can be manufactured under reduced load for denitrification.

Filed: 1989-12-05
Abstract: PURPOSE:To improve the efficiency of document edition processing by providing a pointing device with a position designating function based upon a cursor and an edition command menu selecting function and switching the two functions properly and momentarily. CONSTITUTION:The mouse to be used as the pointing device is provided with the position designating function based upon the cursor 22 and the edition command menu selecting function. When the mouse is moved by continuously depressing the right switch of the mouse, the inter-locking of the cursor 22 is released and the cursor 22 is still stopped on the position as it is where the right switch starts to be depressed. Thereby an invertedly displayed command icon on an edition command menu 23 is changed in accordance with the moving direction and the distance of the mouse. When the mouse switch is released in the inverted display state of a required command icon, the edition command is turned to the command inversely displayed at present. Thus, the efficiency of document edition processing can be improved by properly switching the two functions of the mouse.

Title: Phase synchronizing control device and method therefor
Inventor: HONMA KANENORI
IPC: H04L25/40
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to generate a clock signal while reducing a jitter since a phase step out easily occurs and the clock signal including a lot of jitters are easier to be generated when a data signal of the same code continuation is inputted or the like because the clock signal is not fed back. SOLUTION: When a phase detector(PD) 13 detects a phase difference between a clock signal and an input data signal generated by a gated controlled oscillators(GCO) 11 and 12 and supplies an LPF 16 with it, this LPF 16 supplies the GCO 11 and the GCO 12 with a control signal while phase synchronizing the clock signal with the input data signal; so it becomes possible to prevent step out to the same code continuation and to generate the clock signal with few jitters.

Title: Magnetic field sensor
Inventor: YAMADA ATSUSHI
IPC: G01R33/07
Filed: 1993-12-15
Abstract: PURPOSE:To obtain a small magnetic field sensor which can be formed into optical IC. CONSTITUTION:A magnetic field sensor is provided with a wave conductive path 3 arranged in a magnetic field to be detected, a pair of electrodes 8 and 9 to flow current into the ware conductive path 3, and a detection means 7 to detect a variation in refractive index of the wave conductive path 3 by using a light propagating through the wave conductive path 3. The wave conductive path 3 is formed with a material having Hall effect and electro-optical effect. Also a Hall electric field is produced in the wave conductive path 3 by the current between the magnetic field to be detected and electrodes 8 and 9. Because the wave conductive path 3 has electro-optical effect, refractive index is varied by this Hall electric field. Then the detection means 7 detects a variation in refractive index from propagating light.

Title: Overcurrent protection of switching power device
Inventor: UEKI KOICHI
IPC: H02M3/28
Filed: 1988-12-14
Abstract: PURPOSE:To dispense with fuses by setting the 1st threshold value higher than the normal value flowing to a load and the 2nd threshold value lower than that, by selecting the 1st threshold value ordinarily and by selecting the 2nd threshold value after the specified time over the 1st threshold value. CONSTITUTION:The DC power supply I1 from a DC power source V1 is switched by a transistor 11 and is rectified 21 on the secondary side of a transformer 30 to supply DC constant voltage V0. The current I flowing to a load is detected 51, inputted into a comparator 52 and compared with a 1st overcurrent threshold value It1 or a 2nd threshold value It2 selected by a selection means 60. The 1st and 2nd threshold values are set to 200 to 250% and 110 to 130% or normal loads respectively. Whenever I>It1, a counter 71 starts. After a specified time continued, an FF 72 outputs and switches the selection means 60 to the 2nd threshold value It2. If I>it2 continues for a specified time, it will turn OFF a transistor 11. Effective protection can thereby be made without fuses to transitory overcurrent and continuous overcurrent.
