Title: Method for detecting developing system
Inventor: KIKUCHI SUSUMU
IPC: G03G15/08
Filed: 1992-04-30
Abstract: PURPOSE:To control the concentration of developer and to detect the unloading of a developing unit or the disconnection of a connector by setting the amplitude of the vibration waveform of a toner concentration sensor to be larger than that of a toner concentration control range. CONSTITUTION:A vibration component is given to the waveform outputted from the existing toner concentration sensor 10. One peak value of the vibration waveform is at least set to be larger than the control level value of the concentration of a component agent to be detected in a developing direction. Then, only when a developing device 1 is not loaded or the connector for a developing device is not connected, the pulse output of the vibration waveform or a digital output corresponding to it becomes a level Hi. On the other hand, the digital output is prevented from becoming Hi even in any case that the toner concentration is high or low as for the toner concentration. Therefore, when the developing device 1 is not loaded or the connector for a developing device is not connected, it can be easily detected by detecting the digital output. On the other hand, the toner concentration can be accurately controlled based on the signal state of the pulse output.

Title: Space transmission type optical repeating installation
Inventor: KOYAMA SATOSHI
IPC: H04B10/00
Filed: 1978-11-06
Abstract: PURPOSE:To reduce the noise over a wide band by modulating the input signal through the modulator circuit comprising the free running multivibrator, giving the luminance modulation to the light emitting diode with the output of the modulator circuit and then transmitting the light through the optical system. CONSTITUTION:The input signal obtained by converting the information signal from TV camera 1 or the TV wave from receiver 2 into the base band of the video received undergoes the pulse duration modulation (PWM) through modulator circuit 3 using the free running multivibrator. With this modulation signal, the luminance modulation is given to light emitting diode 4. The radiation light of diode 4 is changed into the parallel light through optical system 5 including the convex lens, the reflector and others to be then transmitted. This transmitted light is condensed by optical system 6 at a remote place to be converted into the electric signal through optical detector 7 such as the PIN diode, the APD and others. Then the input signal is reproduced at demodulator 8 to be displayed at picture receiver monitor 9. This signal process including the modulation and demodulation can be carried out in a digital way. Thus the deterioration can be reduced through the processes, and furthermore chrominance subcarrier can be transmitted without any disturbance since the carrier frequency is increased.

Title: Trim angle controller for marine propelling unit
Inventor: KOIKE TAKASHI
IPC: B63H20/00
Filed: 1985-06-24
Abstract: PURPOSE:To simplify trim angle control by providing an up-controlling switch in a supply circuit of up-signal for increasing the trim angle. CONSTITUTION:In sailing, an accelerator switch 76 is opened and a neutral detecting switch 78 is opened since a shift device is in the advancing position. Now, if the trim angle theta is less than a desired one, the output of a comparing means 66 reaches L level and a switch 56 is closed. Thus, when a trim switch 48 is connected to the up-side, the trim angle increases. And when the trim angle theta equals the desired trim angle, the up-stopping signal of the output of the comparing means 66 reaches H level to open the switch 56. Thus, a propelling unit is maintained at this desired trim angle.

Abstract: PURPOSE:To reduce the positioning accuracy for one of two positioning processes which require high positioning accuracy by etching a dummy conductor pattern formed simultaneously with the formation of a conductor pattern to form a termination part of the 2nd insulated layer. CONSTITUTION:A conductor pattern 3, dummy conductor pattern 10 and the 2nd insulated layer 4 are formed on an insulated layer 2 on a substrate. A photoresist 12 is formed by a spin coating process over such layer 2. Then the substrate is exposed to the light to dissolve the photoresist to be deleted. In this case, the position to be coincident with the edge part of the layer 4 is designated by the edge part of the pattern 10. Therefore, it is sufficient to give exposure to cover the pattern 10. The photoresist 12 is dissolved away after deleting the layer 4 by etching. Then the pattern 10 is dissolved away, and a part 13 of the eaves-shaped insulated layer is deleted by the ultrasonic washing or rubbing. In such a way, a dual spacer pattern is obtained with high accuracy without requiring high accuracy.
