Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To improve the appearance of a light at the time of non-lighting by providing a shielding member for sealing an annular space formed in the periphery of a position lamp device provided in an opening. SOLUTION: In a headlight 10 for vehicle, an annular space formed in the periphery of a position lamp unit 26, which is provided in an opening 24 of a reflector 20, is sealed by a shielding member 32 so as to eliminate a problem of appearance of the headlight 10 that the opening 24 is seen like a black ring when the headlight 10 is seen from a position in front of the headlight 10 at the time of non-lighting. Since a transparent lens is used as a lens 12 to be provided in front of a reflector 20, in the case where the shielding member 32 is not provided, the annular space is seen through the lens 12.  Aluminum deposition is performed to a surface of the shielding member 32 similarly to a reflecting surface 22 of the reflector 20 so that a contrast between the annular space and a reflecting surface of the reflector becomes nearly zero, and uncomfortableness due to the existence of the shielding member 32 is thereby eliminated so as to improve the appearance at the time of non-lighting.

Filed: 1989-12-04
Abstract: PURPOSE:To obtain high speed response by arranging each photodetecting element and an image forming optical system so that one of a plurality of photodetecting elements receives the regular reflection light from a paper to be detected and the other elements receive the reflecting diffusing light from the paper. CONSTITUTION:Photodetecting elements PDa, PDc, PDd among the four photodetecting elements PDa-PDd of a photodetecting array 23 are placed at such a position that they can detect the reflecting diffusing light from a document without receiving the regular reflection light from the surface of a glass plate 11. Moreover, the element PDb is placed where it can receive the regular reflection light from the glass plate 11 and the OHP document. In other words, the element PDb receives the regular reflection light having a reflecting angle theta equal to an angle of incidence theta of a beam spot Pb. The image forming lens 22 condenses the minute diffusing light from the document and forms an image of the reflecting diffusing light from each beam spot Pa, Pc, Pd onto the respective element PDa, PDc, PDd of the array 23. At the same time, the image forming lens 22 forms an image of the regular reflection light from the spot Pb onto the element PDb. In this manner, the apparatus becomes compact with the high-speed responding capability.

Filed: 1990-11-19
Abstract: PURPOSE:To make it possible to test easily the good or bad of the connection points between external signal terminals and wiring patterns on a board by a method wherein a semiconductor integrated circuit is provided with a gate part, which outputs a logical output signal different from that in the case a low-level signal is applied to the input ends of signal pin leads in a state other than the above case, and external power terminals. CONSTITUTION:When connection points 13a to 13f are all connected normally to external leads of a semiconductor integrated circuit 10 and wiring pattern layers 12a to 12f and 15 on a printed board 11 are temporarily made to short- circuit, a low-level signal results in being applied to all of signal pin leads 1a to 1f of an IC chip 1 and an output terminal 8 of an OR gate part 10 shows a low level. When a high-level signal is applied to the leads 1a to 1f when the input terminals are in an open state, the level of the gate circuit output terminal 8 becomes a high level, an output level different from the above level is obtained and an abnormality can be detected. Thereby, it becomes possible that the state of the connection between the external leads of the semiconductor integrated circuit 10 and the wiring pattern layers 13a to 13f is confirmed in an instant.

Filed: 1989-12-01
Abstract: PURPOSE:To secure the secrecy of a data with a shift register of a few stage numbers by switching a generation polynomial of a pseudo random code generating means based on a switching sequence decided by a scramble key. CONSTITUTION:A generation polynomial switching sequence controller 2 decides the switching sequence of the generation polynomial of a generation polynomial variable pseudo random code generator 1 composed of plural stages of shift registers of plural stages in response to the output of a scrambling key generator 3 and generates a pseudo random code of the generation polynomial at a prescribed short time interval. Thus, a pseudo random code series with a different generation polynomial is outputted at the output of the generator 1 at a short time interval. The pseudo random code series is inputted to an exclusive OR computing element 4 together with the input information data series to scramble the input data. Thus, the code series whose generation polynomial is switched sequentially at a short time interval is obtained and the secrecy of data is ensured with the shift registers of a few stage numbers.

Title: Microprocessor
Inventor: SAKAMURA TAKESHI
IPC: G06F9/318
Filed: 1987-12-14
Abstract: PURPOSE:To secure the program flexibility and to facilitate the development of a program for the graphic processing, for example, by storing the information obtained by execution of a 1st instruction to an information holding means and controlling an instruction executing means based on said stored information when a 2nd instruction is carried out. CONSTITUTION:The type of an arithmetic operation is defined as one of operands. In other words, a desired arithmetic operation is carried out by an instruction that is added the operand information designating the type of the arithmetic operation to the outside or the inside of an operation designating part containing a common operation code showing an arithmetic operation (wide sense). Thus the contents of an operand are set previously to designate the type of the arithmetic operation based on the executing result of a certain instruction. Then the arithmetic operation is carried out based on the operand contents by the next instruction. Thus the type of the arithmetic operation can be changed into a dynamic one in a program. In such a way, the flexibility is secured to a program and the development of a program for graphic processing, for example, is facilitated.

Filed: 1986-12-24
Abstract: PURPOSE:To easily detect the floating state of a mortar finished layer by vibrating a surface formed by adhering the mortar finished layer to the surface of a concrete layer by an exciter and detecting its vibration state by a sensor. CONSTITUTION:The finished layer 2 is provided on the surface of the concrete layer 1 and a floating part 3 is formed partially when the finished layer ages. The exciter 4 is arranged on the surface of the finished layer 2 in contact to give vibrations. The sensor 5 is arranged at proper distance from the exciter 4 to detect the vibrations. At this time, if the finished layer 2 floats, the vibrations are not suppressed by the concrete layer 1 and become large and the output of the sensor 5 increases. The exciter 4 uses an energizing spring 6, an electromagnet, etc., for the excitation and the sensor 5 uses a high polymer piezoelectric body, a ceramic piezoelectric body, etc., for the detection. The vibrations are therefore detected, so the floating of the finished layer is inspected by easy operation.
