Title: Combustion control device
Inventor: MATSUMOTO MASANORI
IPC: F23N5/24
Filed: 1978-10-25
Abstract: PURPOSE: To prevent raw gas from flowing out when a controlling device is connected in reverse polarity to a power supply by providing a normally-opened contact for relay operating according to a prepurge timer circuit between a hot terminal and one end of a main valve.  
     CONSTITUTION: A power supply 1 and hot terminals 8, 13 and earth terminals 9, 14 for a controlling device are connected as indicated by continuous line, which are prepurged; where an air blast by burner motor or a flame on pilot burner is detected, a main valve 10 is actuated. Where they are connected in reverse polarity, on the other hand, as indicated by chain line, the main valve 10 is also actuated from the above conditions being satisfied. In this case, where a lead wire 15 is damaged, for example, and its core should come in contact with a chassis or others, the main valve 10 is prevented from coming in operation unexpectedly by a normally-opened contact XP-a2 for relay XP which is actuated by a prepurge timer circuit arranged between the earth terminal 14 and the other end 10b of the main valve 10.

Title: Device for firing discharge lamp
Inventor: WATANABE MOTOO
IPC: H05B41/16
Filed: 1980-09-22
Abstract: PURPOSE:To stably heat a filament for a discharge lamp by bringing the center of the winding width of an output winding of an output leakage transformer coincident to the center of the winding width of a filament winding and allowing the voltages produced at both the windings to become in phase. CONSTITUTION:In a leakage transformer 28, input windings 28a, 28b are wound through a bobbin 37 on a core 36, and a base winding 28c and filament windings 28e, 28f are wound partly thereon. The filament windings 28e, 28f are formed in the lowermost and uppermost layers of the output winding 28d in such a manner that the center of the width of the winding coincides approximately with the center of the output winding 28d. According to this construction, since the voltages of the windings 28e, 28f becomes in phase with the voltage of the winding 28d, the heating states of the filaments 28F1, 23F2 become stable, the formation of the filament spot after ignition is rapid, and the progress of blackening of the discharge lamp due to the energization and deenergization of the lamp can be largely improved.

Title: Measuring device for intensity distribution of beam
Inventor: HAYASHI KENICHI
IPC: G01J1/02
Filed: 1981-08-25
Abstract: PURPOSE:To prevent light from being reflected to a photodetector group by a surface which faces the photodetector group, by providing the facing surface outside of a vacuum area. CONSTITUTION:A glass window 9 is placed at the opposite position to photodetector groups 6a, 6b-6e, and is fixed with a flange 10 to produce a vacuum  internally. Further, a reflected-light preventing cover 11 whose internal wall is  blackened is provided at the outside of the flange 9. consequently, light emitted  from a beam 1 to the glass window 9 passes through the glass window 9 to  reach said cover 11. The cover 11 is set at the outside of the vacuum area, so  the internal wall is blackened easily and the position of the opposite surface is  set easily, thereby preventing the reflection of light to the photodetector groups  6a, 6b-6e easily.

Title: Electrophotographic developing device
Inventor: SOUMA IKUO
IPC: G03G15/09
Filed: 1979-10-15
Abstract: PURPOSE: To prevent the deterioration of the toner owing to developing and minimize the scattering of the developer by performing sequence controlling in such a manner that, when the nonimaging part of a photoreceptor comes to a developing part, the turning of a developer supply member is stopped.  
     CONSTITUTION: In a developing device which develops the electrostatic latent images on an electrophotographic receptor 1 to sensible images by means of a turning developer supply member 2 provided with a developer moving member 3, sequence controlling is performed in such a manner that, just before the exposure part of the photoreceptor 1 comes to a developing time (a time for moving at an angle α) upon entering a copying period, the driving of a sleeve 2 is started to rotate the sleeve 2 only for the time until the exposure part passes the developing part, whereby the drawback of causing the deterioration of the toner by reiterating the sticking and scraping of the toner to and from the sleeve may be eliminated because the sleeve is not driven for the nonimage part of the photoreceptor 1.

Abstract: PURPOSE:To prevent erroneous data transmission by measuring the length of a cable between a console and a terminal equipment, and using a clock adjusted to the clock frequency corresponding to the length of cable, thereby applying data transmission between the console and terminal equipment. CONSTITUTION:When a transfer control section 22 and a transfer clock control means 41 are started, the transfer clock control means 41 stops the control of the transfer control section 22 tentatively to send a test data to a console 3, receives a test data circulated via a bypass means 31, measures the length of cable between the console 3 and the terminal equipment 4 from the circulation time, and adjusts the clock of a clock frequency corresponding to the delay time of the signal transmission due to the length of cable, then moves the control to the transfer control section 22. The transfer control section 22 supplies the adjusted clock to its own terminal equipment 4 and the console 3 to move the content of the SR21 and SR11 connected in ring shape by one bit each, replaces the contents of both the SRs to apply data transfer. Thus, the error in data to be transferred is prevented.

Title: Photomagnetic disk device
Inventor: KATOU TAKESHI
IPC: G02B27/28
Filed: 1984-06-29
Abstract: PURPOSE:To reduce noises due to stray light of an optical system and perform high-S/N reproduction by shaping a polarization beam splitter which separates irradiated light and reflected light in a trapezoid having a slanting surface at the opposite side of the side where light is guided. CONSTITUTION:The majority of light projected by a light source 11 is transmitted through the trapezoidal polarization beam splitter 20 and stopped down by a stop-down lens 13 to form a spot on the surface of a recording medium 14. Further, light reflected by the recording medium 14 is passed through the stop- down lens 3 again while Kerr rotation is caused, and reflected by the polarization beam splitter 20. Then, the light is passed through an analyzer 15 to enter a photodetector 16, which outputs an information reproducing signal. Part of the light emitted by the light source 11 is reflected by the polarization beam splitter 20 and this light (stray light) is reflected by a surface A of the polarization beam splitter 20 or scattered because the surface is a sand ground surface. Consequently, the stray light from the surface A of the beam splitter never enters a photodetector 6.
