Title: Navigation system with capability of instructing running direction
Inventor: TSUJII FUMIO
IPC: G08G1/0968
Filed: 1985-03-27
Granted: 1990-05-09
Abstract: An indication of the position of the vehicle is set onto a map displayed on the colour cathode ray tube (7) by superimposing line cursors in the vertical and horizontal directions, representing north-south and east-west respectively. The cursors may be set by the control push buttons on an operation switch unit, and the destination may also be set from this unit. Other inputs are fed into the microcomputer to indicate bearings via bearing sensors, vehicle speed pulse sensor and mapping and route information from external storage. The map of the are a of the planned route is displayed and the set route followed by a trace of the vehicle's actual position. When a deviation of direction is required a signal is sent to the audio amplifier and relayed to loud speaker giving simulated speech instruction to the driver of the vehicle.

Title: Impact dot-matrix printer
Inventor: SUZUKI KUNIAKI
IPC: G06K15/10
Filed: 1985-08-09
Granted: 1989-04-26
Abstract: This printer reduces power loading during printing of dense black areas, as found in bar charts, by making N repeated scans, in which selected dots are energised.  Printing is controlled by two timing signals; print signal which initiates a dot, and scan signal.  The two timing signals drive two modulo-N counters which feed a coincidence detector which enables a dot only when counter signals are equal.  A dot is enabled when the dot counter is at zero after three counts in scan one.  On the second scan, the scan counter is at one, and a dot is enabled when the dot counter arrives at one, etc. until a completed line is printed in N passes.

Filed: 1986-03-14
Granted: 1993-10-02
Abstract: An apparatus for distributing charge material to a shaft furnace is presented which effectively reduces the segregation of the particles in a storage housing positioned above the shaft furnace. In the present invention, the storage hopper and the distribution device are movable about the vertical axis of the shaft furnace and are mounted inside a sealed chamber. Above the chamber are arranged at least two locks which are each provided with upper and lower sealing flaps. Preferably, the storage hopper and the bottom of each of the locks are in the configuration of tapered funnels, the conical wall of which forms an angle of less than or equal to about 30 DEG  with respect to the vertical axis of the furnace. The storage hopper is preferably supported by support and guide rollers which move on a circular rail integral with the wall of the sealed chamber and is subjected to the action of a drive mechanism for rotation about the vertical axis of the furnace. Anti-segregation boxes are preferably provided both in the locks and in the hopper, to ensure better filling and guarantee a more uniform distribution of the particles of differing granulometry.

Abstract: The circuit consists of a adder, a overflower  to  limit  the output level of adder, a D/A  converter  to  convert  the  digital image signals of the overflower to analog one, a frame  memory  to delay the 1 frame image for a 1 frame,  a  remote  transmitter  to transmit the viewer's selection-key signal, a remote  receiver  to output the signal according to the key signal, a R/W control  part to output the  read/write  signal  to  the  frame  memory,  and  a multiplier to output the fade-out image signal. Current  image  is passed in normal mode, but it is summed with the fade-out image in fade-out mode.
