Title: Mask alignment device
Inventor: KUSE TAKASHI
IPC: H01L21/30
Filed: 1989-12-27
Abstract: PURPOSE:To prevent the generation of a plane defect on a wafer due to the adhesion of duct to a mask by vertically arranging the mask in a part where light rays advance horizontally. CONSTITUTION:Light rays from a light source 1 advance horizontally in a part between first mirror 2 and second mirror 3 and the part is a position where a mask 4 can be arranged vertically. Because the mask 4 is arranged vertically, the dropping direction of dust in the air is parallel to the entrance plane of the light rays from the first mirror 2 and the exit plane of those from the mask 4. Therefore, dust scarcely drops to these planes and adheres thereto. Thus, it is possible to prevent the generation of a plane defect on a wafer 5 due to the adhesion of dust to the mask 4.

IPC: H04Q3/60
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To attain dial-in connection by allowing a line repeater between a public telephone network and a private branch of exchange to select a private branch of exchange side line of the same call reception condition for the arrival of a call from the public telephone network and relaying a call signal from the public telephone network to the private branch of exchange not through a channel switch. SOLUTION: When the user hooks off a telephone set TEL 6, dials a number to send a dial signal, a public telephone network 3 selects a line in a line group K2 and sends a call signal. The line repeater 1 selects a specific line of a line group M2 and relays the call signal to a private branch of exchange 2. The private branch of exchange 2 identifies a dial-in call and replies a primary reply. The line repeater 1 relays it to return the primary reply to the public telephone network 3. The public telephone network 3 transmits a selection signal to the private branch of exchange 2 via a channel through the reception of the primary reply. Since the private branch of exchange 2 receives a called dial-in number, the private branch of exchange 2 allows a telephone set EXT 5-2 being the called telephone set to display the arrival of the call by means of polarity inversion of the channel.
