Title: Laser beam scanner
Inventor: MAKINO TOSHIHIKO
IPC: G02F1/295
Filed: 1988-10-19
Abstract: PURPOSE:To electrically scan a laser beam by forming an optical wave guide having a quantum well structure and a chirp type grating on a substrate and impressing an electric field to the quantum well structure. CONSTITUTION:The laser beam scanner is composed of an optical wave guide 12 having a quantum well structure 14, a chirp type grating 16, a pair of electrodes 18 and 19, etc., provided on a substrate 11. Consequently, when a laser beam L1 outgoing in a direction parallel to the surface of the substrate 11 (a Z direction) is made incident from one edge of the optical wave guide 12 to the internal part of the scanner, the incident light L1 is emitted in a direction intersecting orthogonally with to the surface of the substrate (a Y direction), a converging position P of the outgoing light L2 is determined based on the refractive indices of respective parts to compose the optical wave guide 12 and the cycle of the chirp type grating 16, and since the refractive index of the quantum well structure 14 being a part of the optical wave guide 12 largely changes when the electric field is impressed between both electrodes 18 and 19, the converging position of the outgoing light L2 changes. Thus, the converging position of the laser beam can be changed electrically and continuously.

IPC: B41J2/36
Filed: 1991-10-11
Abstract: PURPOSE:To perform a multi-gradation printing in a thermal printer. CONSTITUTION:A plurality of signals converted on the basis of gradation data are successively transmitted to a thermal head. While heating elements of the thermal head are electrically heated for a predetermined time in accordance with the total width of the signals, ink on an ink sheet is made to adhere onto a recording medium. In this thermal head driving method, a time required for writing and transmitting each signal to the thermal head is (t), and the width of each signal is am. Signals having a relation of am>=t are given priority in selection out of previously held signals. When the total width of the signals coincides with a conduction time corresponding to gradation data, printing is conducted by the signals. If not, a minimum number of signals having a relation am<t are selected in addition to signals having a relation of am>=t. The signals are determined so that the total width of the signals can coincide with a conduction time corresponding to gradation data, and printing is conducted by the signals.

Title: Image projector
Inventor: ADORIANUSU HENRIKASU YOHANESU
IPC: G09F9/00
Filed: 1989-10-13
Abstract: PURPOSE: To make the structure of a picture projector compact by arranging transition structure so that either a 1st light beam or a 2nd light beam may be totally reflected and the other may be transmitted. CONSTITUTION: An angle dependent type beam splitter having the shape of a composite prism element 5 is used to properly separate the beam to the beams b1 and b2 at the part of a projection lens system 20. The element 5 is equipped with two transparent prisms 6 and 7 made of glass or synthetic resin material, and an air layer 8 is formed between the prisms in the element 5. Since the refractive index nm (for example, nm is 1.5) of the material of the prism is larger than the refractive index(n1 =1.0) of air, the beam made incident on a boundary between the prism and the air at an angle θi larger than or equal to a critical angle θ9 is perfectly reflected on the boundary. Meanwhile, in the case the light beam is made incident on the boundary at the angle smaller than the critical angle, it is perfectly transmitted.  Thus, the projection lens system 20 is positioned proximately to a display panel 10, and the picture projector is made compact than in the case it has no prism system.

Title: Refresh control system
Inventor: ONISHI AKIRA
IPC: G11C29/56
Filed: 1985-11-26
Abstract: PURPOSE:To eliminate the need to change a test program according to the type of a DRAM to perform a refresh action and to increase the checking speed with a refresh control system, by providing a timer circuit to set the refresh intervals in response to the DRAM to be checked. CONSTITUTION:The refresh interval of the DRAM to be checked is set by a timer circuit 14 before a refresh action is started. When the refresh action is started, access is started to a microprogram memory 12 through a sequence control part 10. Then the execution of a test program 12A is started. The circuit 14 produces a detection signal every time the time set by the circuit 14 passes during the execution of a test. Thus the part 10 interrupts the execution of the program 12A and executes a subroutine 12B. Thus the refresh signal is sent from a control signal generating part 20 and a refresh action is carried out. As a result, the need for performing time monitor via the test program and therefore the checking time is stortened.

Abstract: PROBLEM TO BE SOLVED: To provide a spread spectrum radio communication equipment that selects a spread code with excellent communication quality in response to the change in the surrounding environment so as to conduct the communication. SOLUTION: A measurement data pattern in a ROM 15 is sent on one hand between two communication equipments and an error of a received data pattern is discriminated on the other hand to calculate the data error rate.

Moreover, another spread code is selected in the communication standby state to conduct reception and setting at communication of the spread code whose synchronization detection number is many by a synchronization detection section 13 is avoided through the discrimination that the spread code is used by other communication.
