Title: Manufacture of semiconductor device
Inventor: OGAWA MASAHIKO
IPC: H01L21/027
Filed: 1990-11-13
Abstract: PURPOSE:To remove the dust from inside a vacuum device efficiently by installing a charge member in the vacuum device, and making it adsorb the charged particles electrostatically. CONSTITUTION:An insulating member 3 such as a glass board, etc., is subjected to the air current being ionized by an ionizer 4. When the member 3 being charged for example, positively by this ionizer 4, is sent into a vacuum device 1, the dust 5 charged negatively inside the vacuum device 1 is adsorbed by the member 3, and is taken out of the vacuum device 1 together with the member 3. Similarly by charging the member 3 negatively, the dust positively charged inside the vacuum device 1 is removed. Hereby, the dust remaining in such narrow or complicated space that the hand of the worker cannot enter can be removed.

Filed: 1988-12-05
Abstract: PURPOSE:To suppress the position of a display surface low and to reduce the fatigue of a user by providing a tilt eliminating mechanism which eliminates the tilt of a tilt mechanism and decreases the radius of rotation when the display surface is switched by a rotating mechanism. CONSTITUTION:A slide member 9 is positioned initially at the spread part of an end part of the cam groove 10 of a guide cam 8. This is rotated by 90 deg. to face a display screen lateral position. When a CRT unit 1 is rotated by 90 deg., the guide cam 8 provided on the rotary support part 3 of the unit 1 rotates synchronously. At this time, the slide member 9 moves as shown by an arrow B to a position 9a. During this period, the slide member 9 does not contact the cam groove 10 and the CRT unit 1 is rotated without tilting. When the unit 1 which tilts downward is switched between the lateral and longitudinal attitudes, on the other hand, the member 9 is positioned at the end part 9b of the part where the cam groove 10 is spread. When the unit 1 is rotated by 90 deg., the slide member 9 moves to 9a or 9c as shown by an arrow C and the member 9 contacts a groove 10, so that the unit is restored to the tilt state.

Title: Manufacture of semiconductor laser
Inventor: NAGAI YUTAKA
IPC: H01S5/343
Filed: 1993-12-10
Abstract: PURPOSE:To obtain both a semiconductor laser having excellent element characteristics in the case of high frequency superposition, and a semiconductor laser having a window structure which can operate at a high optical output. CONSTITUTION:A ridge mask is formed of a film turning to an impurity diffusion source. Impurities are diffused from an impurity diffusion source film to the middle part between a P-contact layer 5 and a P-clad layer 4 by the heat at the time of growing a current blocking layer. The carrier concentration of the P-clad layer 4 is effectively increased, and the element resistance is decreased. Diffusion reaches a quantum well structure active layer 3, and the quantum well structure is disordered, so that a window structure is formed. Since the element resistance is reduced, characteristics in the case of high frequency superposition are improved. By diffusion, the quantum well structure active layer is disordered, and a window structure is formed, so that a window structure semiconductor laser capable of high output operation can be obtained.
