Title: Magnetic reproducing device
Inventor: NAGAI MICHIO
IPC: G11B15/473
Filed: 1990-03-15
Abstract: PURPOSE:To follow the change of the rotating speed of a rotary head so as to extract a specified signal included in a reproducing signal by generating a window pulse for extracting data recorded in the specified area of a track by taking a pulse signal outputted every time the rotary head rotates by a specified angle as a reference. CONSTITUTION:The window pulse for extracting output recorded in the specified area of the track is generated by taking the output pulse signal of a pulse generator 4 synchronizing with the rotating speed of the rotary head of a mag netic reproducing device, which reproduces the data recorded as inclined track on a magnetic tape 2 by the rotary head 1, as the reference. Namely, in the case that the rotating speed of the head 1 is changed, the cycle of the output pulse signal of the pulse generator 4 is changed and the window pulse for extracting the specified recording data is changed to be corresponding one. Thus, the specified recording data is always extracted in appropriate timing.

Title: Image forming device
Inventor: YUKI KAZUHIKO
IPC: G03G15/08
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To appropriately perform the control of an image forming condition based on detection of toner concentration even in the case of making an error in detection of the toner concentration based on the difference of the use state of an image forming device by detecting the use state of the image forming device and correcting a control reference based on a detected result. SOLUTION: The toner concentration of developer is detected by a toner concentration sensor 10 provided on the lower side of a second stirring roller 9. Then, the output value of the sensor 10 and a control reference value are compared, and toner replenishment is controlled so as to make them coincide with each other. Thus, in the case of detecting that the output value is larger than the control reference value and the toner concentration is insufficient, toner is supplied to the inside of a developing device 2 from a toner replenishing device 11. Use frequency is detected and also the control reference value of toner replenishment control is corrected in accordance with the detected result so that the control of the toner concentration is appropriately executed based on detection of the toner concentration even in the case of making the error in the detected value of the sensor 10.

Title: Method for inspecting abnormal part in dielectric dissipation factor of power cable
Inventor: NAGASE SEI
IPC: G01R31/08
Filed: 1985-03-29
Abstract: PURPOSE:To detect accurately a dielectric dissipation factor abnormal part in a very short part by detecting the part of a cable where the surface temperature rises in accordance with the generation of heat in the dielectric dissipation factor abnormal part. CONSTITUTION:A power cable 1 is wound around a drum 3 provided in a measuring position only by one layer. For example, 200-450 kV measuring voltage is applied to the cable 1. If the dielectric dissipation factor abnormal part exists in the insulator of the cable 1, this part generates heat to raise the surface temperature of the cable 1 and the temperature of this part is higher than that of the other normal parts. A thermography detector 2 which detects the temperature without contacting is arranged around the drum 3 in the measuring position so that this detector can be moved in directions of arrows A and B to scan all of the surface of the cable. Thus, even the dielectric dissipation factor abnormal part in a part very shorter than the overall length of the cable to be measured is detected accurately.

Accordingly, as a light-emitting region can be provided on the wide area other than the part directly under the electrode and in the vicinity of its side face, the light of long wavelength taken out from the side face can be maintained. As a result, the color of emitted light can be unified efficiently, there is no erroneous recognition, and a highly brilliant semiconductor light-emitting device can be realized.

Filed: 1993-03-25
Abstract: PURPOSE:To prevent the generation of skew when the passing/ being-passed of writing and reading addresses occurs, in a field synchronizer in which two asynchronous video signals are allowed to synchronize with each other by using a field memory. CONSTITUTION:A first video signal from an input terminal 16 is written in a field memory 1 by reset signals generated by a write reset generating part 2 and a write dot counter 3. Then, the data are read by the reset signals generated by a read reset generating part 6 and a read dot counter 7 by using a second video signal from an input terminal 17 as a reference. The generating timing of the reset signals is controlled according to the output of a passing control part 5 which detects the passing/being-passed between the addresses generated by the write dot counter 3 and a write line counter 4, and the addresses generated by the read dot counter 7 and a read line counter 8. Thus, the timing of the horizontal synchronizing timing of the video signals to be read can be made constant, and the discontinuity of horizontal synchronizing signals can be prevented.

Filed: 1993-03-03
Abstract: PURPOSE:To decrease the number of parts and to reduce the cost of production by integrally forming a slider for operating opening and closing of an opening/ closing cap, a member for energizing an engaging lever and the sliding body and a member for energizing the opening of the opening/closing cap. CONSTITUTION:A lock lever 3 moves in the same direction and a pawl 7 of the lever 3 is disengaged from the front end 8a of a hook part 8 if an open button 1 is slid rightward in the state of closing the opening/closing cap 105 of a disk player. The cap 105 is pushed up to open by the energizing force of a spring 4 for pushing up the opening/closing cap. A push spring 5 engages with the inner flank of the body and acts to return the button 1 toward the left when the button 1 is slid to the right side. Then, the button 1 restores the initial state and the lever 3 returns to its home position as well so as to be reset to the position where the lever faces the hook part 8 of the cap 105 and, therefore, the hook part 8 and the pawl 7 are engaged with each other and the cap 105 is put into the closed state simply by pushing down and closing the cap 105. The number of parts is reduced and the cost is reduced by integrally forming the opening/closing devices in such a manner.

Title: Heater for color printer
Inventor: NOUYAMA TAKAYUKI
IPC: B41M5/124
Filed: 1987-03-20
Abstract: PURPOSE:To completely eliminate the danger that a color forming precursor and a color developer may fuse with the other substance even if melting, by a method wherein, a gloss developing sheet is provided with coating-free surfaces having no layer of a developer and a gloss agent on the right and left sides thereof and it is carried by endless belts which come into contact with only the aforesaid surfaces, and heating is conducted by a heating element which is so fixed as to abut against the backside of the developing sheet. CONSTITUTION:A gloss developing sheet 1 having coating-free layers is carried by endless belts 2 on a carry board 3. At this time, the carry board 3 is brought into close contact with the endless belts 2 because of its curved shape. Therefore, the gloss developing sheet 1 having coating-free surfaces is also carried in close contact with the carry board 3. Then, the sheet 1 is heated by a heating element 4 from the backside thereof, whereby the color forming reaction on the surface is accelerated and a gloss agent is made glossy. Therefore, the absence of an object abutting against a coating surface of the gloss developing sheet at the time of heating enables the heating to be carried out without the occurrence of fusion.
