Abstract: PURPOSE:To eliminate that one part of a light waveguide is broken off and to enhance the productivity even in a wafer where an easily cleavable direction of a crystal of a semiconductor substrate is different from that of a split direction by a method wherein a groove part in a direction which is different from an easily cleavable direction is formed in a wafer and the wafer is split along the groove part. CONSTITUTION:A semiconductor wafer is formed by laminating a multi-layer structure 12 on a semiconductor substrate 11 by epitaxial growth; groove parts 16 in a direction which is different from an easily cleavable direction of the substrate 11 are formed in the wafer; after that, the wafer is split along the groove parts 16. For example, a multilayer structure 12 is laminated on an n-type GaAs (111) plane substrate 11; an SiNx film 13 is evaporated onto the surface; stripe parts 15 acting as electric current passages are formed in such a way that they are perpendicular to a cleavage face 14 of a crystal; a p-side electrode is evaporated. Then, stripe-shaped groove parts 16 are formed on the rear of a wafer in parallel to the stripe parts 15 of the electric current passages; after that, an n-side electrode is evaporated; a bar-shaped small piece 17 is taken out by making use of the cleavage face 14. A crack 19 is produced along the groove parts 16; after that, the small piece is split into laser elements by using an adhesive sheet.

Title: Electromagnetic shield
Inventor: HARADA TAKASHI
IPC: H05K9/00
Filed: 1991-04-16
Abstract: PURPOSE:To obtain a sufficient shielding effect for leakage of an electromagnetic wave for use in a seam of a metal housing or a periphery of a door.

Title: Pwm driving device
Inventor: TOKI NOZOMI
IPC: H03K7/08
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent PWM pulse from being outputted in the absence of a signal by providing a 1st PWM modulation part which outputs a 1st PWM pulse proportional to the absolute value of an input signal and an inverting amplifier which outputs a 2nd PWM pulse having the opposite polarity from the 1st pulse and outputting the 1st or 2nd PWM pulse according to the polarity of the input signal. SOLUTION: The PWM modulation part 2 outputs the PWM pulse P1 having pulse width proportional to the absolute value of the input signal and the inverting amplifier 4 outputs the PWM pulse P2 having the opposite polarity from it. Further, a differential output amplifier 7 outputs the PWM pulse outputted from a polarity changeover switch 5 as a PWM pulse P3 without inversion and its inverted PWM pulse P4, respectively. Therefore, a pulse train having an amplitude value twice as large as that of the PWM pulse P3 or P4 is outputted between two output terminals of the differential amplifier 7. When there is no signal, PWM pulse wave is not outputted, so there is no unnecessary power consumption in the absence of a signal.
