Title: Automotive headlamp
Inventor: KUREBAYASHI TOSHIHIKO
IPC: F21S8/10
Filed: 1990-11-30
Abstract: PURPOSE:To prevent a lead support from giving a bad effect on the light distribution of a sub-beam by providing the longer lead support for supporting the front end part of a discharge. lamp in a position corresponding to the horizontal surface of the lower reflecting surface of a reflector. CONSTITUTION:A reflector 12 has a multiple reflecting surface form having different focusing point distances between an upper reflecting surface 13 and a lower reflecting surface 14. The focusing point of the upper reflecting surface 13 is Fa nearly in the rear of a discharge part 32, the focusing point of the lower reflecting surface 14 is Fb nearly in front of the discharging part, and a long lead support 24 is disposed near the lower side of a horizontal surface passing nearly the center of the discharge part 32. Therefore, the light reflected by the lower reflecting surface 14 of the emitted light, of the discharge part 32 of a discharge lamp, is directed slightly downward to an optical axis L, forming a second sector light distribution pattern having a central angle smaller than 180 deg., while the light directing close to a horizontal surface 15a, of the light directing the reflector lower reflecting surface 14 from the discharge part 32, is shielded by an insulating cylinder body 28, forming a form in which the sector side edge part is slightly cut. Thus, the light distribution of the sub-beam has no effect by the shadow of the lead support.

Title: Charged particle energy analyzer
Inventor: KODAMA TAKETSUGU
IPC: H01J49/44
Filed: 1987-12-28
Abstract: PURPOSE:To dissolve the disturbance of the electric field at end edges of electrodes by covering the opening face of the end edge sections of semi-spherical concentric double electrodes with a resistance film and feeding a current in the direction of the electrode radius. CONSTITUTION:A ceramic substrate 3 is fitted so as to close the opening between semi-spherical concentric double electrodes 1 and 2, a conductor film 4 is formed on the surface on the side toward the space between the electrodes, and the film 4 is made of a resistance film. A conducting layer 41 is formed facing flanges 11 and 21 on the inner periphery and the outer periphery of the film 4. When the voltage is applied across the electrodes 1 and 2, a current flows in the direction of the electrode radius, and the desired potential gradient is obtained. The above resistance layer is made thick in proportion to the distance from the center of the electrodes 1 and 2, thus the potential in the resistance film is changed in reverse proportion to the distance from the center. On the other hand, the potential across the electrodes 1 and 2 is in reverse proportion to the distance from the center. When both inner and outer edges of the resistance film and the edges of the electrodes 1 and 2 are connected, the potential at each point of the resistance film becomes the same potential as the correct potential across the double electrodes 1 and 2. The disturbance of the electric field at end edges of the electrodes is dissolved.

IPC: H02M7/483
Filed: 1994-12-21
Abstract: PURPOSE: To provide a power converter which has a capacity and function equivalent to those of a power converter using elements with the same loss characteristic and is suitable for reducing the loss of the whole converter. CONSTITUTION: A power converter is constituted by using elements with different loss characteristics on a phase bases, such as low on-loss elements GTO3 and GTO4 and low switching-loss elements IGBT5-IGBT8 and constituting the x-phase constituted of the GTOs in two-level output and y-phase constituted of the IGBTs in three-level output, and then, changing the number of output levels of each phase. The low on-loss elements are switched to each other by using long-period signals based on the reference wave of output voltage and the low switching-loss elements are switched to each other at high speeds by performing PWM control.  Therefore, the withstand voltages of the elements can be used efficiently and the distortion of the output waveform of the converter resulting from the x-phase constituted of the low on-loss elements can be corrected by performing PWM control, because the element loss in each phase can be reduced and the withstand voltage in each phase can be made equal to that in another phase.

Title: Electronic component transfer equipment
Inventor: KAWADA TOSUKE
IPC: H05K13/00
Filed: 1993-12-28
Abstract: PURPOSE:To provide an electronic component transfer equipment wherein a load is less applied to an electronic component or a mounting object work even if a component holding head is moved up or down at a high speed. CONSTITUTION:A part holding unit 80 is supported by a solenoid 114 fixed to an up-down slide 120 through an engaging member 110 from below. The solenoid 114 is excited to attract the component holding unit 80 to the up-down slide 120 when the up-down slide 120 is accelerated descending, whereby the up-down slide 120 is made to descend together with the part holding unit 80 even if descending acceleration is larger than gravitational acceleration. When the up-down slide 120 is decelerated descending, the solenoid 114 is demagnetized to cancel an attractive force, and the component suction head 90 is made to come into contact with an electronic component after the descending speed becomes almost zero. By this setup, the up-down slide 120 travels an additional descending distance as easily separated from the component holding unit 80, so that only the weight of the component holding unit 80 is applied to an electronic component. When an electronic component is mounted on a printed board, only the weight of the component holding unit 80 is applied to the printed board in the same way as above.
