Abstract: PROBLEM TO BE SOLVED: To increase interchangeability by making the light rays with different wavelengths are generated by light sources A, B incident selectively on disks varying in thicknesses, diffracting the reflected light rays the respective wavelength bands of holograms A, B, receiving these beams by photodetectors A, B and detecting electric signals. SOLUTION: At the time of reproduction of the thin/thick disks (DVD/CD, CD-R) 17/18, the light rays (solid lines/dotted lines) from the first/second light sources 11/11' of the long/short wavelengths are used. The respective light rays thereof advance rectilinearly as they are through the first/second holograms 13, 14 of a hologram plate 12 in the incident direction and are made into parallel beams by a collimating lens 15. The parallel beams are converged to the disks 17/18 by the entire/small part of the numerical aperture of an objective lens 16. The greater part of the light quantity of the reflected light rays are diffracted by the holograms 13, 14 and are received by the first/second photodetectors 19/20.  As a result, the problem of the increase in aberrations by a difference in the thicknesses between the disks is overcome and the reproduction of even the phase transition disk is made possible. The interchangeability is thus increased.

Title: Exhaust gas purifying system
Inventor: HIRAMATSU TAKUYA
IPC: B01D53/04
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To effectively remove HC, etc., generated at the time of cold start by incorporating H type β-zeolite having a specified ratio of SiO2 to Al2 O3 into an adsorptive body. SOLUTION: H type β-zeolite in which the ratio of SiO2 to Al2 O3 is >=100, preferably >=200 is used as a principal adsorptive component contained in an adsorptive body. The reason why the H type β-zeolite is excellent in adsorbing characteristics is that it can adsorb even large molecules because of large pore diameter, molecules to be adsorbed can penetrate into the zeolite from all directions and diffuse well because of three-dimensionally connected pores and the zeolite has high adsorption capacity because of large pore volume. The resultant adsorptive body can maintain satisfactory adsorbing and desorbing characteristics even when exposed to exhaust gas at >=750 deg.C from an internal- combustion engine and hydrocarbons desorbed from the adsorptive body are satisfactorily decomposed on a catalyst.

Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To improve the detection precision of a coordinate input position by spreading a probe light in the direction almost parallel to and perpendicular to a coordinate input surface. SOLUTION: Irradiation light beams emitted from a light emitting element 111 are converged by a cylindrical lens 112a to be made into almost parallel light beams which have a slight thickness in the direction of an x-axis and a slight expansion in the negative direction of a z-axis. These light beams are converged in the direction of a y-axis through two cylindrical lenses 112b and 112c to be converged at the position of a slit 113, thereby forming a linear light source. They are spread in a fan shape toward a surface parallel to the coordinate input surface 102 from this linear light source, so that the surface has a certain thickness in a direction perpendicular to the surface 102 to be advanced nearly in parallel while spreading the little beams. Thus, the detection precision of a coordinate input position is improved.

Title: Input/output device for information
Inventor: SUZUKI NORIYUKI
IPC: G06F3/043
Filed: 1986-10-31
Abstract: PURPOSE:To ensure the operating feeling more approximate to the normal writing or drawing jobs by controlling the output conditions set in an input mode of information in response to the information on the writing pressure detected by a writing pressure detecting means. CONSTITUTION:A shown waveform detecting circuit contains a circuit which extracts the information on writing pressure as a peak level of a detection signal obtained by a vibration sensor 6 by making use of a fact that the amplitude of the vibration transmitted to the sensor 6 varies by the level of the writing pressure. The signal amplified by a preamplifying circuit 51 is inputted to an A/D converting circuit 59. Thus the amplitude information is always converted into a digital signal having a prescribed quantized step and the converted data is inputted to a latch circuit 510. The circuit 510 latches the input data in synchronism with the timing signal which is outputted from an envelope peak detecting circuit 53 by the peak detecting timing. Therefore this data means the information on the writing pressure of a vibration pen 3 and the display output is controlled based on said information on the writing pressure.

Title: Vertical plate guiding method for underwater runner
Inventor: NOMURA SHIGEYUKI
IPC: B63G8/00
Filed: 1993-10-15
Abstract: PURPOSE:To improve a target searching capacity of an underwater runner by always cruising the runner toward a target. CONSTITUTION:When an arithmetic unit 4 of a controller 2 in an underwater runner inputs a guide signal 8 generated from a launching ship, it receives a program signal 10 from a ROM 3, and obtains a pitch angle difference between an instructed guiding pitch angle of an underwater runner and an actual pitch angle at the time of generating the guide signal according to this program. A control signal 9 in which the pitch angle difference is zero is output to control a steering system 6 to provide a pitch angle instruction system different from a conventional depth instruction system. Thus, since the runner always cruises toward a target, a target searching capability can be improved without altering various units of the runner.
