Title: Lighting device for discharge lamp
Inventor: MIYAZAKI MITSUHARU
IPC: H05B41/24
Filed: 1987-12-07

Title: Input interface circuit
Inventor: SATO KOICHI
IPC: H03K19/018
Filed: 1987-12-07
Abstract: PURPOSE:To reduce the number of elements used and reduce the power consumption of the circuit by inputting outputs of switching elements driven by the level of external input signals to IILs and providing resistances in series on the drive input side of the switching elements and, at the same time, connecting the drive inputs of the switching elements to the outputs of the IILs through resistances. CONSTITUTION:In case the level of external input signals Vin rises from 'L' to 'H' and exceeds a fixed threshold Vth, both of transistors Q1 and Q2 are switched from turn-off states to turn-on states. Then the inputs of IILs I1 and I2 change from 'H' to 'L' and their output Vout is switched from 'L' to 'H'. When the level of the external input signals Vin becomes lower than the threshold Vth after the output Vout of the IILs I1 and I2 is once switched to 'H', the output Vout returns to the 'L' state from the 'H' state by opposite operations. Therefore, the input interface circuit of IILs with hysteresis can be constituted of a circuit with a less number of elements and a lower power consumption.

Title: Reflector for head lamp
Inventor: MATSUMOTO NAOYOSHI
IPC: F21S8/10
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a reflector for a head lamp with which light distribution pattern without upward warp in both end parts of the right and left sides can be obtained. SOLUTION: Since the horizontal cross-section shape of a reflecting face segment 70 has a projected and curved shape with a large curvature radius, the cross-section shape covering from a filament F of a light source bulb of the reflecting face segment 70 to both end parts of the right and left upper sides also has a projected and curved shape with a large curvature radius. Consequently, as compared with a reflector having a conventional reflecting face segment with a projected and curved shape with a small curvature radius, the reflection angle α deg. of reflected light becomes small for the incidence angle α deg.of luminous fluxes from the filament F of the light source bulb reaching both end parts of the right and left upper sides of a composite reflecting face is small.  As a result, since the reflected light is not so much upward, the light distribution pattern through a lens 12 is formed to be a light distribution pattern without upward warp in both end parts of the right and left upper sides.
