Abstract: PURPOSE:To contrive to upgrade the element characteristics of a semiconductor device in a simple process by a method wherein, after an etching was performed on the substrate, low-concentration impurities are previously ion-implanted on the whole surface of the substrate and after a masking material was stayed remained in the recessed part of the substrate, high-concentration impurities are separately ion-implanted in the sidewall parts of the recessed part. CONSTITUTION:A thermal oxide film 2 and a polycrystalline silicon film 3 are formed on the whole surface of a semiconductor substrate 1, and after that, masking materials 4 are selectively formed. The substance 1 is performed an etching in such a way as to have a tapered angle using the masking materials 4 respectively as a mask. Impurities of the same conductive type as that of the substrate 1 are selectively ion-implanted in the whole surface using the polycrystalline silicon film 3 as a mask. After an insulating film 6 was deposited, a masking material 4' is formed. An etching is performed on the film 6 using NH4F. Impurities of the same conductive type as that of the substrate 1 are ion- implanted in sidewall parts 8 only using the polycrystalline film 3 as a mask. As a result, the generation of any parasitic channel can be prevented, because high-dose impurities have been already implanted in the corners.

Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To efficiently clean air over a wide range. SOLUTION: A centrifugal blower 18 is arranged in underwater in a tank 4. When the centrifugal blower 18 and an exhaust fan 2 are subjected to rotary driving, fresh air is sucked in through an air inlet duct 3. This air is discharged from discharging ports 26 on the side face of the centrifugal blower 18 rotating in underwater in the tank 4, and is forcibly passed through water and cleaned. The cleaned air rises in an air outlet duct 10, and is discharged to the outside from an air outlet 44 through the exhaust fan 2. Since this air cleaner 1 does not require consumables such as a filter, cost is lowered and air is cleaned over a wider range than that of an ion type air cleaner.

Title: Mobile station information collecting method
Inventor: KITSUGIYA SADAMU
IPC: H04B7/24
Filed: 1993-01-14
Abstract: PURPOSE:To recognize whether a mobile station is included in a prescribed area or not with no waiting time required by providing a time frame for a common answer at the head of the answer signal received from the mobile station after a base station transmitted the vehicle search signal of a specific mobile station to all mobile stations. CONSTITUTION:The control center of a base station transmits at a time the vehicle search signals produced by an information processor 20 to the mobile stations mounted on the vehicles in a fixed area by a controller 30 in a signal form suited to a radio equipment. The mobile station mounted on a specific vehicle of a relevant area transmits an answer signal to the base station. The base station detects the presence or absence of both common and individual signals sent from the corresponding mobile station by an answer detecting part 10. Then the processor 20 decides the presence or absence of a vehicle that answered in the relevant area based on a fact whether an answer detection signal is received or not in a time frame for a common answer set at the head of the answer signal. Therefore the base station can know the presence or absence of an answered vehicle in a relevant area at the end of the preceding time frame. Then if the relevant mobile station is absent, the base station can produce the next vehicle search instruction.
