Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of leakage current and crystal defect by relieving concentration of stress in only one direction, in an IGBT(insulated gate bipolar transistor) having stripe-shaped trench gates. SOLUTION: In this manufacturing method, the inside of a terminal region 11 of an IGBT 10 is divided into one gate pad region 12 and three element regions 13a, 13b, 13c with wiring regions 14.

Title: Electromagnet
Inventor: ITOU KOUJI
IPC: H01F3/10
Filed: 1979-03-16
Abstract: PURPOSE:To obtain electromagnet simple in construction and satisfactory in response property by providing a structure whose electric resistance becomes large in the direction rectangular to the line which a magnetic flux passes in at leas one gap at magnet frame or armature. CONSTITUTION:Voltage is removed by deenergizing an exciting coil 1, however, an electromagnetic energy stored in an electromagnet appears in a circuit as current, and even if a transient current is attenuated by self-inductance L and resistance R of the exciting current 1 at time constant L/R, an eddy current is capable of working in the direction to prevent magnetic flux from decreasing in a magnet frame 2. However, the eddy current on this part will be suppressed by constituting a gap 3 with a laminated iron plate 10 and making the face of the iron plate 10 directional same as the magnetic flux, and thus the magnetic flux is extinguished quickly. Reponse property is improved accordingly.

IPC: G03G15/00
Filed: 1979-03-16
Abstract: PURPOSE:To make the potential state of a developing device, transfer device, etc. simple by uniformly charging a recording medium and performing the discharging of the polarity opposite from the uniform charging with a pin electrode. CONSTITUTION:This is so constituted that uniform charging is done on a recording medium 7 by a corona charger 8, thence start pulse 10 and print pulse 11 are respectively applied to the electrodes P1, P2 of the pin electrode 9 of the pair construction installed non-contactually with the recording medium 7 and that discharging is done at the electrode end face to generate positive and negative ions. Positive ions, attracted by the electric field in the gap part, deposit on the recording medium 7 and remove or decrease part of the charges, thereby forming a latent image. Since the magnitude of the electric field in the gap part is controlled by applying the uniform charging beforehand to the recording medium 7 in this way, there is no need for applying bias voltage to the belt body and the potential state of the developing device, transfer device, etc. may be made extremely simple.

Abstract: PURPOSE:To reduce an external leakage magnetic flux by composing front and back brackets for supporting a rotor and a stator on the same shaft of a magnetic material, and magnetizing the brackets in a reverse direction to the magnetizing direction of a permanent magnet, thereby increasing the effective magnetic flux. CONSTITUTION:A rotor 1 of a motor is composed of a rotational shaft 2, a permanent magnet 3 and rotor yokes 4a, 4b magnetized in an axial direction. A front bracket 5 is integrally formed with an outer peripheral cylinder 5a, inner peripheral cylinder 5b, a disc 5c for closing the outer end of a magnetic material, and a rear bracket 5 is composed similarly.

In the thus step motor, the brackets 5, 6 are magnetized in a reverse direction to the magnetizing direction of the magnet 3. Thus, effective magnetic flux A is increased to reduce the leakage magnetic flux. Further, the brackets 5, 6 are composed of a magnetic material having coercive force lower than that of the magnet 3, thereby readily magnetizing them.

Title: Camera and exchange lens
Inventor: YOSHIDA HIDEAKI
IPC: G03B15/03
Filed: 1989-02-09
Abstract: PURPOSE:To realize zoom flash and shadowless photographing by providing a light branching means which reflects a part of light in a light path leading from an image forming lens to an image forming plain and emits it from the image forming lens to the outside and allows a part of the incident light from the image forming lens to form an image on the image forming plain. CONSTITUTION:A light emitting part 8 is provided so as to emit light toward the optical path of an image forming system in a direction intersecting orthogonally with this optical path of the image forming system, and a half mirror 9 as the light branching means is provided on a position where the emitting light from the light emitting part 8 crosses the optical path of the image forming system. Consequently, when an object is irradiated by the light from the light emitting part 8, 50% of the rays of light among the incident rays of light, from outside is transmitted through the half mirror 9 to image- forme on the image forming plain 2 or emitted to the outside from a finder window 7. Since the optical axis of the system is thus completely the same as that of the emitting light, the object is eliminated from shading; when a lens group 1 is a zoom lens, a light emitting range is changed according to the focul distance of the lens group 1, and zoom flash is thus realized.

Title: High-strength calcined compact of zirconia and production thereof
Inventor: KIJIMA NAOTO
IPC: C04B35/48
Filed: 1988-02-12
Abstract: PURPOSE:To obtain a high-strength calcined compact of zirconia improved in bending strength, by hydrothermally treating a calcined compact of zirconia containing tetragonal zirconia as a constituent crystal phase at a specific temperature. CONSTITUTION:A calcined compact of zirconia containing tetragonal zirconia as a main constituent crystal phase is hydrothermally treated at 60-300 deg.C to subject the surface of the calcined compact to crystal phase transfer from tetragonal zirconia to monoclinic zirconia. Thereby, the aimed calcined compact is obtained. The treating time may be relatively short in the case of about 200 deg.C treating temperature. The treating time must be prolonged with increasing difference between 200 deg.C and the treating temperature. The phase transition is hardly advanced at <60 deg.C and apparatus cost is increased at >300 deg.C. Thereby, the high temperature is industrially unsuitable. Methods for dipping the calcined compact in water and simply bringing steam into contact with the surface of the calcined compact are convenient and preferred for the hydrothermal treatment. The hydrothermal treatment is preferably carried out after precise machining the surface of the calcined compact.

Abstract: PURPOSE:To eliminate a noise due to antenna switching without an audible sense of incongruity by using an output changeover means to select an output of a delay means in correlation with an output of a detection means and to provide an output when plural antennas are switched. CONSTITUTION:An audio signal is detected by an audio detection circuit 26 via a front end 23 and in IF circuit 24 and inputted to a delay changeover circuit 31. In this case, since the state is a normal state other than a vertical blanking period, no antenna switching signal is outputted from a diversity control circuit 29. Since a synchronizing separator circuit 28 generates a synchronizing signal for the vertical blanking period, the diversity control circuit 29 generates the antenna switching signal and an antenna 21 is selected by an antenna changeover circuit 22. Furthermore, a control signal generating circuit 34 gives a control signal to a delay changeover circuit 31 based on the antenna switching signal and the delay circuit 30 is used to select an audio signal delayed by one wavelength for one wavelength and the audio signal is given to an audio multiple demodulation circuit 32.
