Title: Thermal head driving control device
Inventor: NOGUCHI AKIO
IPC: B41J2/36
Filed: 1991-06-28
Abstract: PURPOSE:To prevent the influence of heat of heating elements in the surrounding, which are driven simultaneously or with a slight time delay, from happening, and keep the recording density uniform. CONSTITUTION:An image signal 13 which passed through a serial/parallel converter 12 is fed to memories 14, 15 and correction data buffer 16. The correction data buffer 16 stores the image signal 13 for a total of 4 lines with the image signal 13 for a line which is fed presently as the latest one. A data operation circuit 24 creates correction data 25 for print density correction, based on the image signal 13 which is stored in the correction data buffer 16. Image signals 17, 18 which are read from the memories 14, 15 and the correction data 25 are rearranged in response to the driving method of a thermal head by a rearrangement circuit 19, and are fed to the thermal head 42 through data buffers 32, 34, and print motion is performed, based on the data.

Title: Driving controller for sewing machine
Inventor: SATOU MOTOYOSHI
IPC: H02P3/06
Filed: 1980-11-12
Abstract: PURPOSE:To cut off a power source automatically when an operator has left it ON carelessly and thereby avoid wasting power, by a method wherein time is counted after the stopping of the driving of the sewing machine is detected, and when the counted value has reached a predetermined value, a stopping signal is generated to cut off the power source. CONSTITUTION:When a sewing operation is finished and the stepping-in on a pedal is released, a lever 1 is returned, a microswich 6 is turnred OFF and a timer circuit TM starts to count time. In the case of interrupting the sewing operation with a microswitch SW2 left ON, when the counted value reaches a preset value, the timer circuit TM generates an abnormal signal, whereby a transistor TR is turned ON to energize a relay R2, and a contact R21 is changed over from NC side to NO side so as to de-energize a relay R1. The supply of power to a motor M is stopped due to the turning-OFF of contacts R11-R13, and the voltages on the primary and secondary sides of a transformer T are reduced to zero, and after a capacitor C is discharged, the relay R2 is also de- energized. Then, the machine can be started by depressing a reset switch SW1.

Title: Storing case for disk
Inventor: HONDA KOICHI
IPC: B65D85/00
Filed: 1994-06-16
Abstract: PURPOSE:To smoothly put in/out a compact disk and prevent damage of the compact disk at the time of temporarily placing as much as possible by coupling a lid to a case body by a function of an elastic working piece and applying force to the lid in the direction for opening by an elastic tab formed on a side. CONSTITUTION:A storing case 1 is put on a palm, and by pushing pressing recesses 11, 11 of elastic working pieces 9 by fingers, the working pieces 9 are bent inward to release engagement between an engaging claw 12 and a locking stage 27. This disengagement allows restoring elastic force of elastic tabs 16, 16 to function, so that a lid 20 is opened with respect to a case body 2 on its pivotal side. Since the elastic tabs 16, 16 are provided on a support axis side 7 at this time, even slight restoration of the tabs 16, 16 to a protruding position allows the tabs 16, 16 to rotate as largely as possible. Thus while a compact disk is held by the other hand, the lid 20 can be easily opened completely.

IPC: F02M47/02
Filed: 1995-06-26
Abstract: PURPOSE: To decrease the spray travel distance in the initial stage of fuel injection by closing a needle valve after a solenoid valve is operated in a direction in which high-pressure fuel acts on the needle valve when fuel is not injected, and sealing the needle valve through a process of fuel pressure by the solenoid valve when fuel is injected. CONSTITUTION: An injection control solenoid valve 23 makes high-pressure fuel from a high-pressure fuel inlet 31a act on a hydraulic piston 29, and applies it to a nozzle needle 26, and closes the needle valve. The injection control solenoid valve 23 removes pressure to be applied to a hydraulic piston 29 and the nozzle needle 26, so that the nozzle needle 26 may be freely moved. A discharge amount control solenoid valve 9, the injection control solenoid valve 23, pressure sensors 11a, 11b are connected to an ECU 40. A function for changing the electrification time of an injection control pulse of main injection according to the fuel injection amount is set in the ECU 40. In the main injection, fuel is injected by the pattern in which the injection initial stage is in the low pressure fuel injection range and then made into the high pressure fuel injection range.  Therefore, injection pressure in the injection initial stage is always low, and the injection travel distance can be decreased.

IPC: G01C19/00
Filed: 1983-08-31
Abstract: PURPOSE:To obtain a converter where the number of output pulses in a certain time is selected freely to obtain required high precision and high resolution, by generating a pulse which has a 1/n period tau in oscillation period of a dynamic system and has the same polarity as the output of a positive/negative discriminating means, and generating reference pulses having a 1/(n.N) period in oscillation period which adjusts and matches the positive/negative time of feedback by a tau/N-fold time of the difference between the number of positive pulses and that of negative pulses in this oscillation period. CONSTITUTION:A sampling circuit 6 performs sampling with clocks having a period tau shorter than an oscillation period T of a pendulum 1, and considerably many pulses are generated in its output e2. These pulses e2 are sent to a counter 8 simultaneously with outputting. Reference clocks from a generator 30 are divided by a frequency divider 31 to obtain clocks having an n.N-fold period of the period T (n.N is an optional positive integer) when the oscillation period of the pendulum is T-number of seconds, and a difference (i-j) between a number (i) of positive pulses and a number (j) of negative pulses of pulses e2 in this period is outputted to a feedback current generating circuit 9. If the value (i-j) is positive, the time of a feedback torque is made shorter by a time (i-j)tau'; but if it is negative, the time of the feedback torque is made longer by the same time.
