Title: Electrophotographic sensitive body and manufacture of same
Inventor: TAKIMOTO AKIO
IPC: G03G5/05
Filed: 1987-07-01
Abstract: PURPOSE:To enhance mobility of carriers and sensitivity of a photosensitive body and to lower residual potential by forming an electric charge transfer layer made of a specified polymer compound. CONSTITUTION:The photosensitive body is formed by successively laminating the charge transfer layer 2 and a photoconductive layer 3 on a supporting body 1. The layer 2 is made of a straight-chain polymer compound having p-phenylene units combining with at least one of S, Se, and Te atoms of IVb elements at the para position, and in addition, 0, such as poly-p-phenylenesulfide (PPS), and for example, it is formed by applying the PPS film to the substrate 1, and heat treating it, preferably, in an atmosphere containing O2 at a temperature of 250-350 deg.C. It is preferred to form an amorphous layer made of Si containing H and/or halogen (X), such as Si(:H:X), as the layer 3.

Title: Semiconductor laser device
Inventor: TAJIRI FUMIKO
IPC: H01S5/00
Filed: 1983-09-07
Abstract: PURPOSE:To form the titled device of low noise having the small fluctuation of photo-output by a method wherein said device is allowed to have the distribution of effective refractive index high in a part along one direction of the P-N junction of a semiconductor and low on both sides thereof and to have a current injected region of band form vertical to one direction and shallow in its diffused region at the center. CONSTITUTION:This device is composed of a groove 2 of an N-GaAs substrate 1, an N-Ga0.65Al0.35As clad layer 3, an N-Ga0.95Al0.05As active layer 4, a P- Ga0.65Al0.35As clad layer 5, an N-GaAs cap layer 6, a Zn-diffused region and current injected region 7, a P-side electrode 8, and an N-side electrode 9. The light generating in the above-mentioned active layer 4 is not absorbed to the groove 2 of the substrate 1 because of the sufficient thickness of the clad layer 3, but absorbed to the substrate 1 on both sides of the groove 2; accordingly the stabilization of basic lateral mode oscillation can be realized. Since the depth of the diffused region 7 does not reach the clad layer 5 at the center, two streaks of longitudinal mode oscillation are inhibited, and therefore single longitudinal mode oscillation can be always realized.

The holding body 25 thus obtained is disposed on an outer circumference of a tube 24 to correct a disturbance of a magnetic field of an electrostatic magnetic field generator. Uniformity of the magnetic field is expressed by a difference between the maximum and minimum values obtained as a result of the measurement of the magnetic field as divided by a mean of the magnetic field. When a specified uniformity is not attained, a mean vector is determined to correct. The use of the magnetic field generator having an electromagnetic field homogenizing means allows a reduction in errors for correction without deviation in the height of the permanent magnet piece.

Title: Horizontal deflecting circuit
Inventor: MAEKAWA HITOSHI
IPC: H03K4/64
Filed: 1981-10-19
Abstract: PURPOSE:To allow a horizontal driving transistor (TR) to rise in an optinum period by making a collector pulse rise period of the TR coincident with timing set by a timing circuit. CONSTITUTION:A flyback pulse FBP is shaped by a waveform shaping circuit 12 into a rectangular wave having the opposite polarity, and the wave is delayed at a part by a period Treff to form  a waveform F. A rise of this waveform F and a rise of the collector waveform C of a driving TR4 are detected by a phase detecting circuit 14, whose output is adjusted by a charge pump circuit 15 and an LPF16. When the pulse C rises after the waveform F rises, a control voltage H applied to a monostable multivibrator 11 is lowered to shorten the time width of an output waveform B. When it reses before the waveform F, the voltage H is raised. Consequently, a rise of the pulse C of the TR4 is delayed invariably the period Treff behind the ending point of the positive half period of the pulse FBP without reference to variance of elements and fluctuations of temperature.

Abstract: PURPOSE:To obtain constant emission intensity regardless of the size of a duty in an emission pattern by controlling the gain of a control signal for the laser emission intensity on the basis of laser emitting data for the turning-on and off control of emission in a laser light source. CONSTITUTION:The gain of the control signal for the laser emission intensity is controlled on the basis of the laser emitting data for the turning-on and off control of the emission in the laser light source. Namely, an information data signal to be recorded to an optical disk 1 is sent to a signal processing circuit 9 and the signal of the emission pattern, for which information data are modulated in the signal processing circuit 9, is sent to an emission driving circuit 7 and a gain control circuit 8. Here, a signal to pass through an LPF5 of an APC circuit is simultaneously inputted to the gain control circuit 8 and the signal of the emission pattern, which is modulated in the gain control circuit 8, and the signal to pass through the LPF5 are subtracted and after that, sent to the emission driving circuit 7 again. Thus, regardless of the size of the duty in the emission pattern, a laser light, for which the peak value of emission power is arranged, can be obtained.

Title: Digital radio telephone set
Inventor: SUMI YUJI
IPC: H04W88/02
Filed: 1992-06-24
Abstract: PURPOSE:To inform it to the user that a slave set is moved outside a radio wave arrival range by providing an electric field strength detection section and a received tone adjustment section to the slave set and decreasing the received sound volume accordingly when the electric field level approaches a talking disable level. CONSTITUTION:When the user makes a call from a slave set 11, an electric field strength detection section 9 provided for the slave set 11 detects an electric field level and transfers the result to a control section 8. The control section 8 compares the result of electric field level detection with a communication disable level and controls a reception sound volume adjustment section 10 when the detected level is larger than the disable level and allows a reception section 4 to output a voice signal in a usual reception sound volume. Furthermore, when the electric field level detection result indicates that the level is lower than the communication disable level, the control section 8 controls the reception sound volume adjustment section 10 to set the reception sound volume low in response to the result of electric field level detection. Thus, when the user is going to move to the outside of the radio wave arrival range from the master set during talking, the control section 8 controls the reception sound volume adjustment section 10 decrease the reception sound volume thereby informing it to the user of the slave set 11 that the slave set is moving to the outside of the arrival range of the radio wave from the master set.

Title: Method of plating iron core

Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To use established facilities as they are, by setting up iron core material into iron core form, and temporarily fixing separation parts or division parts, and masking the separation parts or the division parts with the iron core material itself. SOLUTION: For this stator iron core, the iron core material 10A where the iron core 10 is separated in the middle, and the base 2 is provided with cuts 5... separately for each tooth 1, and the bases 2... are unfolded in roughly rectilinear form through coupling parts 21 is manufactured by the press punching of a steel sheet. Then, it is closed so that the separation parts 6 may accord with one another, and cramp-shaped metal fittings 50 are inserted into holes 22 for fixation so as to temporarily fix them. Hereby, it turns out that separation parts 6 and the cuts 5 mask the opposite side with each other in condition that they are closed and fixed, so this does not need a special masking member or an exclusive jig or tool.  Moreover, the form of the iron core material 10A closed and temporarily fixed is the same as that of an ordinary iron core 10, so plating treatment can be performed, using existing plating treatment facilities.
