Title: Production of shadow mask
Inventor: ADACHI TATSUYA
IPC: B21D22/20
Filed: 1985-10-31
Abstract: PURPOSE:To prevent the reduction in the curved face accuracy due to a springback and to obtain the shadow mask of high accuracy by setting the forming temp. at each part so that the parts more than two places of a blank may show the springback value in a different direction after forming while under forming. CONSTITUTION:The springback in a different direction happens respectively on the 1st forming part 15 and 2nd forming part 16 when a thin metallic blank is press-formed by a metal die 11. And moment Ma works after the press forming and the curved surface accuracy is reduced. Now, the temp. at the 2nd forming part 16 is set higher than the temp. of the 1st forming part 15 by utilizing that the springback value becomes smaller than the temp. in forming in order to work the reverse moment Mb. The reduction in the surface accuracy of the shadow mask is then checked by working the reverse moment Mb against the moment Ma.

Title: Control circuit for burner
Inventor: MUTO YOSHIO
IPC: F23N5/12
Filed: 1986-10-15
Abstract: PURPOSE:To prevent occurrence of an oxygen deficiency accident by judging whether or not a flame current detecting circuit performs a normal motion, by a method wherein, through control of a test switch during combustion, a burner is forcibly brought into an abnormal combustion state, and when it is judged by the flame current detecting circuit that the burner is in an abnormal state, combustion is stopped. CONSTITUTION:By actuating a test switch 26 by a user during combustion in order to detect whether a flame rod 12 and a flame current detecting circuit 11 are normally worked or not, an analogue switch 7 is opened. When a flame ion current value is decreased and the output potential of an amplifier 49 is decreased to a combustion stop level, a low level combustion stop signal is outputted from a comparator 50 to a control circuit 1. The power source of a pump control circuit 9 is shut off to stop driving of an electromagnet pump 10, and a burner motor control circuit 3 is controlled so that the operation of a burner motor 5 is stopped. Thus, combustion is stopped, and it can be detected that the frame rod 12 and the flame current detecting circuit 11 and the like are normally actuated.

Patent JP-H03107368-A (JP)
Title: Dc-dc converter
Inventor: ARAKAWA KOJI
IPC: H02M3/28
Filed: 1989-09-20
Abstract: PURPOSE:To reduce loss and to simplify the structure by connecting inductors in series with rectifying diodes in respective rectifying circuits and connecting a capacitor in parallel with the output side of the rectifier circuit. CONSTITUTION:A transistor Q1 is turned off when a capacitor C4 is discharging current, i.e., when current IQ1 is zero. When the capacitor C4 is discharged completely, current supply to a load R1 is carried out by the reset current of a choke coil L3 flowing equally through diodes D1, D2. Charge/discharge current of the capacitor C4 flows to the output side at all times without being collected at the input side. Furthermore, switching loss is hardly produced because the transistor Q1 is turned on/off under the condition where the current IQ1 is zero. Consequently, loss can be reduced by means of the inductors L4, L5 and the capacitor C4 and the circuitry can be simplified.

Abstract: PURPOSE:To provide a low cost structured apparatus capable of meeting printing conditions of even flexible thick paper by operating an ink sheet loading means at a signal from a recording paper detection means, positioning ink sheet to recording paper through transport driven by a platen roller and transporting them together. CONSTITUTION:The clockwise drive of a motor 2 and the energization of a thermal head 30 are commenced by detecting an index 22a and recording paper 21 with a photosensor 60, 61 and obtaining 'AND' output. At that time, both ink sheet 22 and recording paper 21 are integrally fed by a platen roller 1. If a required amount of printing in a single color (yellow) is terminated, the thermal head 30 is disconnected, resulting in the feed of the ink sheet 22 by the amount of M. If the 22b part arrives at the thermal head 30, a motor 25 is driven in a maintained direction to release the pressing operation and stop the motor 2. Thus both papers come to a standstill..This operational sequence is so designed as to be achieved by a micro computer or other proper means after setting the length of ink application on the ink sheet 22.

Title: Dust radiation monitor apparatus
Inventor: SAKAMOTO YUKINORI
IPC: G01T1/167
Filed: 1988-09-30
Abstract: PURPOSE:To certainly judge the clogging of filter paper by particles or the closure of sampling piping by comparing one of or both of the measured values of a flowmeter and a pressure gauge with a preset value. CONSTITUTION:When a suction pump 10 is driven by the pump control part of a dust radiation monitor apparatus, air containing dust passes through the filter paper 4 of a dust collection part 2 from a sampling gas inlet (a) and further passes through a flow control valve 8 and a flowmeter 9 to be discharged from a sampling gas outlet (b) by the suction pump 10. The pump control part 21 takes in the measured flow rate from the flowmeter 9 continuously or at a cycle faster than a filter paper replacing cycle to compare the same with the set flow rate of a flow rate setting part 22. When the measured flow rate is smaller than the set flow rate, an abnormal signal is sent out to set unused filter paper 4 to the dust collection part 2 and, thereafter, a cause is judged while the state of the measured flow rate is observed. By this method, the clopping of filter paper can be certainly judged from the closure of sampling piping.
