Title: Stereoscopic image processor and stereoscopic image processing method
Inventor: YOSHIOKA YOSHIHIRO
IPC: H04N5/262
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To further enhance operation convenience in a stereoscopic image processor. SOLUTION: A desired reference direction is selected among plural reference directions that are preset on a display screen of a display means 21 and the reference directions are successively switched in predetermined order while performing a desired image processing based on the selected reference direction for a stereoscopic image that is displayed on the display screen. Thus, the reference direction in easily selected only by performing easy operation since separate and independent execution of operation to select the reference direction and operation to perform the image processing is not required.

Title: Liquid crystal device
Inventor: MORI HIDEO
IPC: G09G3/20
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To prevent flickers in a screen or unnatural movement in a display region for a moving picture and to obtain high definition in the display region for a still picture. SOLUTION: Scanning on gate lines 1 is performed for a certain number of gate lines which pass a display region A1 for an moving picture, and the number of lines for scanning is determined by considering the size of the region A1. The gate lines 1 not passing the display region A1 for the moving picture are not scanned. The source voltage is applied only on the source lines 2 passing the display region A1 for the moving picture but the voltage is not applied on the source lines 2 not passing the region A1. By scanning the plurality of lines as above-mentioned, the refresh frequency in the display region A1 for the moving picture can be increased, which prevents flickers or unnatural movement of a screen.  Since no source voltage is applied on the source lines not passing the display region A1 for the moving image, decrease in the definition in the display region B1X for a still picture due to scanning of the plurality of lines can be prevented.

Title: Semiconductor laser device and manufacture thereof
Inventor: YAMAMOTO SABURO
IPC: H01S5/042
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To grow a thick contact layer, without bringing on characteristic failures or reliability failures of a semiconductor laser device. SOLUTION: A p-type GaAs contact layer 9 of 20 μm or more is grown by the temperature difference liquid phase epitaxial growth (LPE) method at a Ga solution temperature stationarily higher than the substrate vicinity temperature on a semiconductor multilayer film, having an active layer 5 sandwiched between a pair of clad layers 4, 6. This makes uniform the doping concentration of Zn or Mg in the layer thickness direction, and hence a satisfactory surface carrier concentration is obtained for forming an ohmic contact with a p-type electrode 10, without raising the carrier concentration at an initial growth stage. With the active layer 5 includes a quantum well layer of 10 nm or less, the contact layer 9 is growth through the temperature difference LPE with a substrate temperature of 700 deg.C or less.  Since the diffusion of Zn or Mg into the quantum well layer can be made small, the characteristics degradation due to breakdown of the quantum well is avoidable.

Abstract: PURPOSE:To contrive to make uniform printed density without losing energy, by controlling the heating value of a heating resistor by impressing a pulse train having a constant pulse width and a varying period in accordance with the temperature of a substrate of a thermal head. CONSTITUTION:In accordance with a detection signal from a temperature-detecting part 14 for detecting the temperature of the substrate of the thermal head, a pulse train having a period increased with a rise in the temperature is outputted from a pulse oscillating circuit 15 to trigger a monostable multivibrator 16, thereby outputting a pulse train having a constant pulse width and a period varied in accordance with the temperature. The pulse train is impressed on a power amplifying circuit 4 through an AND gate 17 opened by a printing timing signal from a printing signal outputting circuit 1 and an AND gate 3 operated in response to a printing signal from the circuit 1, whereby the heating value of the heating resistor 5 in the thermal head is controlled. Accordingly, by controlling the heating value by only the period of the pulse train without changing the pulse width of the impressed current and an impressed voltage, printed density can be made to be uniform without losing energy.

Abstract: PURPOSE:To obtain a sufficient deviation required for communication and to attain frequency modulation with excellent modulation characteristic by using a signal being the integration of a modulation signal so as to control the center frequency and the group delay time of a variable phase equivalent device and passing the carrier through the variable phase equivalent device to obtain the frequency modulator. CONSTITUTION:A carrier generator 11 outputting a carrier, a variable phase equivalent device 21 whose center frequency is varied, and an integration device 13 are provided, the center frequency and the group delay time of the variable phase equivalent device 21 are controlled by using the signal being the result of the modulation signal integrated by the integration device 13, the carrier passes through the variable phase equivalent device 21 to obtain the frequency modulator. Thus, the frequency modulation is applied directly to the carrier regardless of the lockup time of the changeover of the carrier. Then a large delay time is obtained with less number of elements by the variable phase equivalent device 21 and an optional change in the delay time is given easily to the carrier. Thus, the deviation required for communication is obtained sufficiently and the frequency modulation with the excellent modulation characteristic is applied.

Title: Surface plate for rotary polishing machine
Inventor: OGISO HIROYUKI
IPC: B24B37/16
Filed: 1987-03-25
Abstract: PURPOSE:To protect a work from being broken or scratched by employing a non-linear groove, e.g. a groove formed with circles having no corner portion, for feeding polishing agent and making line or point contact with a work thereby reducing impact. CONSTITUTION:When a block 1 (a portion surrounded by grooves 2) is composed of circles of various sizes, a work and a block 1 of a surface plate collide constantly regardless of the direction of a work being determined by the rotation of a surface plate and a carrier, thereby they collide with low impact. It is true even for reverse rotation and polishing agent can be fed to all corners. When a block 11 is constructed with spiral grooves 12a and semi-circular grooves 12b made between the central portion and the outer circumferential portion of the surface plate, rotary direction is fixed but the block 11 does not make line contact with the work, thereby the impact is made small.
