Title: Manufacture of semiconductor device
Inventor: UGA KIMIHARU
IPC: H01L29/732
Filed: 1990-08-16
Abstract: PURPOSE:To prevent damage to a silicon substrate caused by etching by etching a first polysilicon film on an emitter layer in such a way that it is left somewhat without removing it completely and by implanting impurities for the base layer via an oxide film. CONSTITUTION:When a second oxide film 111 and a first polysilicon film 100 are etched with a first resist film 700 as a mask. the first polysilicon film 100 is left somewhat without removing it completely. The first polysilicon film which is left is denoted by reference numeral 100A. Next. the left film 100A is oxidized completely and an oxide film 100B is formed. A P-type impurity is implanted into an epitaxial layer 3 under the film 100B in an active region of a transistor via the film 100B. and an intrinsic base layer 7 is formed. As this prevents damage to a silicon substrate caused by etching, leak current of a transistor can be reduced and transistor characteristics can be improved. In addition, the performance of transistors can be increased because thin junction is formed.

Title: Aligner and method therefor, and manufacture of semiconductor devices and masks
Inventor: KAGAMI ICHIRO
IPC: G03F1/20
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To reduce errors in width of track patterns due to the displacements of unit patterns. SOLUTION: Transmitting parts 20a of unit patterns 20 formed on a mask transmit incident electron beams. Intercepting parts 20b intercept the incident electron beams. Semi-transmitting parts 20c of a width W formed at both ends of the transmitting parts 20a cause the incident electron beams to be transmitted at a transmittance of 1/2. When exposure is performed and track patterns are formed through the use of such unit patterns, the semi-transmitting parts 20c are overlaid with one another. As a consequence, since connection parts between the track patterns are exposed to electron beams which are transmitted through the semi-transmission parts 20c exhibiting an intensity of 1/2 of normal intensity two times, the error of width of the track patterns due to displacements of the unit patterns can be reduced.

Title: Treatment of malodorous exhaust from garbage treatment
Inventor: DOUGLAS FAA
IPC: B09B3/00
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To easily and excellently deodorize malodorous exhaust having a high content of moisture. SOLUTION: Malodorous exhaust is discharged when garbage is charged into a treating vessel 1 incorporating a crushing mechanism, the garbage in the vessel 1 is heated, dried and powdered, and the garbage is treated and the malodorous exhaust is treated by this method. In this case, the malodorous exhaust discharged from the vessel 1 is brought into contact with ozone, hence even the malodorous exhaust having a high content of moisture is excellently deodorized, since ozone is soluble in water and has a sufficient oxidizing capacity even when dissolved.

Title: Machine condition displaying system in numerical controller
Inventor: ARAI HIROAKI
IPC: G05B19/4063
Filed: 1985-09-28
Abstract: PURPOSE:To easily monitor the condition of a machine even if a circuit diagram, etc., is not referred to, by displaying the S, T, and M commands of a numerical controller, names of output apparatuses which receive the commands, and names of input apparatuses which confirm the operating condition of the machine upon receiving the operation commands. CONSTITUTION:A control section 10 always receives S, T, and M operation signals from an input-output storage section 4 and, when a machine is set to an S, T, and M operation executing condition, discriminates which S, T, and M command are executed out of the S, T, and M commands and reads a relevant command from a command value storing section 3. At the same time, the control section 10 reads the name of a pertinent input-output apparatus from an input-output apparatus name storing table 11 and sends the name to a displaying data storing section 12. The storing section 12 rearranges the data in accordance with the displaying form of the CRT displaying screen of a control panel 1 and displays the current machine condition on the CRT displaying screen. Since the operating condition is also displayed in such a way, the S, T, and M operations can easily be monitored by watching the CRT screen only and the cause of a fault can easily be analyzed even if a circuit diagram, etc., is not referred to each time.
