Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a hologram polarizing and separating element which is free of heat generation due to the absorption of an unnecessary polarized light component and excellently separates polarized light and reduces the weight and the size of a system. SOLUTION: Natural light I which is made incident on the surface of a hologram 1 at right angles is separated into 1st linear polarized light E1 which travels without being diffracted and 2nd linear polarized light E2 which is diffracted by the hologram 1 and has its polarization direction at right angles to the 1st linear polarized light E1 . The 1st linear polarized light E1 passes through base glass 2 as it is, but the 2nd linear polarized light E2 is totally reflected inside on the glass-air border line and unable to exit to the projection side of the hologram polarizing and separating element. Therefore, this hologram polarizing and separating element can pass only one linear polarized light component of the natural incident light in a predetermined direction.

Filed: 1990-03-26
Abstract: PURPOSE:To prevent lowering of engine output and vibration of an engine due to dispersion in the amount of intake air by shutting or deflecting intake air using the partition plate of a first wall portion when the amount of intake air is small or the partition plates of first and second wall portions when the amount is large. CONSTITUTION:In a portion between the openings 9b to 9e of a lower wall portion 9a inside a surge tank 9, partition plates 71 to 73 are provided between the lower wall portion 9a of a first wall portion and the side wall portion 9f of a second wall portion so as to shut out intake air permitted to flow from upper to lower side. The area of each lower portion 71a to 73a that shuts out the intake air is set in such a manner as being enlarged from the upper to lower side of the flow of the intake air and the area of each upper portion 71c to 73c that shuts out the intake air is largest on the lowest side of the flow and is second largest on the uppermost side of the flow. When the amount of intake air is small the area of each rib of the lower wall portion 9a that shuts out the intake air is larger on the lower side of the flow of the intake air, thereby preventing concentration of the intake air in the intake air opening 9e on the lowest side of the flow. When the amount of intake air is large the area of the rib 72 that shuts out the intake air is small and so intake air returned to the upper side of the flow of the intake air is introduced into the opening 9c so that distribution of the intake air into each cylinder combustion chamber is uniformed.

Filed: 1992-02-27
Abstract: PURPOSE:To eliminate generation of a data error which is caused by a permanent trouble of a nonvolatile memory by replacing a primary memory with a spare secondary memory partially when the former fails. CONSTITUTION:When a vehicle drives for a specified distance (a unit driving distance) and a specified number of pulse signals from a sensor 1 are counted, an operation processing part 2 writes the unit driving distance into a primary memory 31 and at the same time the most recent driving distance is displayed on a display 4. Also, data within the memory 31 is read out properly. thus judging whether the data was rewritten properly or not. In the case of an error, one word containing a part which was rewritten is written into a secondary memory 32 for holding the driving distance data. Furthermore, when the writing failure is not a fixed one for this judgment but is caused by an external noise, rewriting is made. On the other hand, in the case of a normal rewriting, the memory 31 is used. Then, rewriting is disabled, it is written into the memory 32.

Title: Telephone system
Inventor: AOKI TAKASHI
IPC: H04M11/00
Filed: 1990-03-26
Abstract: PURPOSE:To interrupt and restart data communication in response to a command from a data terminal independently of an exchange job at a center by providing a communication control function to an interface means between the data terminal and the center. CONSTITUTION:When interruption is desired during data communication, a personal computer(PC) sends an interrupt command to a data terminal interface section (DIU) 27. The interrupt command is received by a microprocessor 77 for data communication control in the DIU 27. The processor 77 selects its operating mode from the means mode into the control mode. Since the PC is disconnected from a channel B2 by the mode changeover, even when a communication data from other PC is sent to the DIU through the channel B2 in this case, the data reception is rejected in the DIU 27. In the case of restarting the interrupted data communication, the PC sends a restore command to the DIU 27. Upon the receipt of the command, the processor 77 in the DIU 27 changes over the operating mode from the control mode into the communication mode and the PC is again connected to the channel B2.

Title: Noise removing method for video signal
Inventor: JOGO HISAZUMI
IPC: H04N9/64
Filed: 1988-03-31
Abstract: PURPOSE:To prevent the deterioration of picture quality by individually removing a noise component for a carrier chrominance signal and another noise component for a luminance signal in a video signal. CONSTITUTION:The noise component of the carrier chrominance signal out of all the noise components is extracted at a band-pass filter 14, inputted to a first non-linear processing circuit 15, and inputted to a subtracting device 16. Since the noise component from a subtracting device 12 is inputted to this subtracting device 16, the subtraction between the noise component from the device 12 and the noise component of the carrier chrominance signal is executed, and the noise component of the luminance signal is fetched and inputted to a second non-linear processing circuit 17. Since noise removing signals outputted from these first and second non-linear processing circuits 15 and 17 are added to a current video signal at adders 19 and 20 and outputted to an output terminal 21, the noise component of the carrier chrominance signal of the current video signal and the noise component of the luminance signal of the current video signal are individually removed. Thus, the deterioration of the picture quality can be prevented.

Abstract: PURPOSE:To measure a step without contacting by providing a variable wavelength light source, a photodetector and an arithmetic processing part, a means which cuts off diffracted light of degree zero or light other than the diffracted light of degree zero, etc., so as to cause interference. CONSTITUTION:A sample 44 is irradiated with light having proper wavelength. Further, a spatial filter 12 is moved to a position 11 and the sample 44 is observed through an ocular 32. Then, a scale plate 30 associated with a spatial filter 22 is moved to put a measurement position within a mark 31.

At this time, the diffracted light of degree zero is cut off by the filter 21 and only diffracted light reaches the filter 22. Then, the signal of the photodetector 23 is inputted while the wavelength of the irradiation light is varied and this light is converted photo electrically and processed by a microcomputer 39. This processing corrects spectral characteristics of the light source 2, lens system, and optical system firstly. Then, wavelengths with which the maximal and minimal values of variation in interference intensity are obtained are found and the step is measured from an expression containing the found maximal and minimal values.

Title: Micro-fresnel lens
Inventor: AOYAMA SHIGERU
IPC: G02B3/08
Filed: 1988-03-31
Abstract: PURPOSE:To facilitate the manufacture and to decrease the chromatic aberration by specifying the height of an uneven pattern in each Fresnel zone. CONSTITUTION:Height of an uneven pattern of each zone is set to a value for giving a phase shift of 2npi (n is a positive integer of >=2). Accordingly, a period of each zone becomes two times, comparing with a conventional Fresnel lens having a value for giving a phase shift whose height is 2pi. That is, even in case of the same numerical aperture NA, the period of each zone becomes (n) times by setting the height of the lens to (n) times. In such a way, the manufacture accuracy is improved, the lens efficiency is raised, and also, the period of the Fresnel zone is lengthened, by which a light beam is curved by a refraction rather than a diffraction effect, and a chromatic aberration caused by a use wavelength variation is decreased.
