Filed: 1981-07-09
Abstract: PURPOSE:To move a recording head accurately at a small pitch in an outgoing path and to return the recording head to the original position at a high speed by driving a pulse motor by a one phase and two phase excitation method. CONSTITUTION:A control circuit 7 controls the operation of the recording head and the pulse motor 2 in accordance with the instruction from an input means 8. The control circuit 7 comprises a CPU, an ROM, an RAM, and PIO. In the ROM, control programs and character pattern generating codes are stored. The control circuit 7 imparts forward rotation pulses and reverse rotation pulses to a pulse motor driving circuit 13 in order to control the pulse motor 2.

Title: Laser power control circuit
Inventor: KANEKO SHINJI
IPC: H01S5/068
Filed: 1995-04-10
Abstract: PURPOSE: To record a data with an optimal laser power without causing breakdown of a laser. CONSTITUTION: A driver 12 is subjected to APC control with the output from a comparator 16 such that a current, indicative an optimal laser power, is produced from a photodiode PD when a laser diode LD emits light during an APC interval. When an actually measured laser power PAC obtained at the time of recording data is lower than a laser power PDC obtained during APC operation, a correction value for bringing the laser power PAC at the time of recording data close to the rated value during APC operation is added (level shift operation) to the laser power output by means of a level shift circuit 30 with respect to the laser power PDC obtained during APC operation.  Since the correction value is added only at the time of recording data, rated operation of laser diode is nor exceeded during APC operation, ice. at the time of DC recording, and thereby the laser diode is protected against breakdown.

The object 4 to be painted subjected to the thermal treatment is sent to a light source section with rollers 14 and when the object 4 to be painted is irradiated with a laser light, the laser light is diffracted by the painting particles S. By condensing the diffraction light with a condenser lens 7, a ring-shaped diffraction image is obtained behind a group of particles. As a diameter of the diffraction light ring and an intensity distribu tion are correlated with a particle size distribution (size of particles), a particle size distribution (size of particles) on the object 4 to be painted can be measured. Analysis of a diffraction image pattern correlated with the particle size distribu tion is performed with a computer 15.

Title: Path switching system in atm network
Inventor: MUTA AKINORI
IPC: H04Q3/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To predicate an incommunicable path not based on a failure place, to replace it with a spare path and to avoid communication disconnection by preliminarily setting a fixed logical path for management through a PVC on a transmission path between ATM switches. SOLUTION: When a communication terminal a5 communicates with a communication terminal b6, a logical connection via a transmission route e-a-b-f is established. If a failure occurs on a transmission path b8 during conversation, an ATM switch a1 does not receive a response frame of a loop back test through a fixed logical path a13 any more and detects failure occurrence on the route of the path a13. The switch a1 refers to a static path selection table, sets a switching flag of an entry that has a high priority to 'one' among plural entries that are to the same ATM address destination which is monitored by the path a13 and makes an entry that has a low priority a reference destination. Therefore, when the terminal a5 makes a call out request, connection is established via a spare route e-d-c-f which has a low priority and communication is performed.
