Title: Data processor
Inventor: ONODERA NORIO
IPC: G06F11/10
Filed: 1980-07-28
Abstract: PURPOSE:To eliminate the need for a memory for parity bits, by generating check bits prior to the use of a data processor. CONSTITUTION:A no-check mode is set in initial loading and a central processor 4 reads the contents of memories 1-0 and 1-3 for data storage successively. Namely, the contents of addresses #0 are read out to generate parity bits corresponding to the contents by a parity generating/checking circuit part 9, and the parity bits are written in the address #0 of a memory 3 for check bit storage. Thus, parity bits corresponding to the contents of the memories 1-0 and 1-3 are newly generated prior to the use of a data processor.

Title: Method for trimming ink jet recording head and ink jet recorder
Inventor: MORIGUCHI HARUHIKO
IPC: B41J2/05
Filed: 1989-04-25
Abstract: PURPOSE:To obtain uniformity in an image even if an ink jet recording head possessing a plurality of jet orifices with different jet quantities is used by imparting energy of a normal pulse or more to a trimming pulse and impressing a predetermined number of trimming pulses equivalent to jet orifices. CONSTITUTION:If an OD value of a dot formed with ink liquid drops jetted out of 256-arrayed jet orifices is irregular, trimming pulses equivalent to each OD value are impressed on the resistance heating element of each jet orifice so that all dots come to the maximum OD value, because a 100th dot has the maximum OD value, that is, the maximum jet quantity. Namely, a predetermined number of trimming pulses are impressed on each jet orifice, whereby each jet orifice changes in its jet characteristics, and the OD values of dots corresponding to all jet orifices become identical (ODc) by impressing recording pulses in the subsequent recording action. Thus, jet quantity is corrected in response to an irregular images being generated to obtain uniform images.

Title: Geomagnetic azimuth sensor
Inventor: SHIMIZU OSAMU
IPC: G01R33/09
Filed: 1985-05-16
Abstract: PURPOSE:To enable a vehicle advancing azimuth to be detected by providing a magnetic resistance effect element with a region which approximately linearly changes in accordance with an intensity of magnetic field. CONSTITUTION:Magnetic resistance effect elements RX11 and RY12 are arranged so as to intersect each other at right angles as a sensor. Resistors R13 and R14 are connected to the elements RX11 and RY12 in series, respectively, to form a circuit. Magnets MX15 and MY16 supply a bias magnetic field for fitting the values of the elements RX11 and RY12 to the central portion of a linear region. When the sensor is rotated by one revolution by applying a D.C. voltage V0, change electric resistance values RX and RY in X and Y directions, respectively. That is, assuming that the geomagnetic azimuth does not change, changes in the resistance values of the resistors RX and RY corresponding to the rotary angles of the sensor with respect to the north direction are taken out as output voltages VX and VY, respectively. Thus, a vehicle advancing azimuth can be detected with a high reliability by a small size, light weight and low demand instrument.
