Title: Semiconductor manufacturing method
Inventor: KITAMURA KENJI
IPC: H01L27/092
Filed: 1994-07-15
Abstract: PURPOSE:To reduce channel dosage, which adjusts a threshold voltage, by forming an n-type well layer after a p-type well layer is formed. CONSTITUTION:Patterning is made by using a p-type well region mask. After a photoresist is used for selective etching of a silicon nitride film 5, ion implantation of a p-type impurity boron is performed over a dosage range from 1E12/cm<2> to 5E12/cm<2>. The impurity boron is treated with diffusion and activation to form a p-type well 4. Next the remaining silicon nitride film 5 is removed and ion implantation of an n-type impurity is conducted for dosage of 2E12/cm<2>. Heat treatment at 1150 deg.C for 6 hours is performed for diffusion and activation of an impurity phosphorus and a n-type well layer 3 is formed. At this time, the p-type well 4 formed beforehand is subjected to heat treatment and further diffusion. In the succeeding process, an n-channel MOS transistor is formed on this p-type well layer 4, and a p-channel MOS transistor on the n-type well layer 3.

Title: Protection device of apparatus from over-pressure
Inventor: PETERU FUREIRINKU
IPC: F16K17/02
Filed: 1990-06-25
Abstract: PURPOSE: To protect a device from excess pressure positively and with good reproducibility even when the excess pressure is low by allowing a valve to abut on a nozzle connected to a space in a device by a specified force caused by air pressure independent of the pressure in the space. CONSTITUTION: With an excess pressure protection device, a substrate 1 is arranged and in a cover 3 a valve 2 is arranged, and above the valve, cavities 13, 14 are defined by ribs 15. A tube 9 provided in the substrate 1 is connected to vacuum spaces of epitaxy reactor, etc., and a tube 8 of the cover 3 is connected to atmospheric pressure. Vacuum in an area between two seals 4, 5 causes the valve 2 to abut on a valve seat of a second nozzle 7 for adjusting pressure between atmospheric pressure and the initial vacuum, and further to abut on the ribs 15. The vacuum in the vacuum reservoir is fixed to a half of normal atmospheric pressure, and when an excess pressure of about 0.05 bar or more is applied in the tube 9 the valve 2 is separated from the substrate 1 to exhaust excess pressure gas from the tube 8.  Thus a device can be positively and with good reproducibility protected from even low excess pressure.

Title: Combustion cylinder
Inventor: OGINO TOSHIROU
IPC: F23D3/10
Filed: 1982-09-20
Abstract: PURPOSE:To widen the area of irradiation and improve the efficiency of irradiation as well as to widen the range of adjustment of volume of combustion by a method wherein an air hole projected upwardly is arranged in a combustion chamber. CONSTITUTION:In a combustion chamber A, a local eddy current is produced under an action of fed air flow near an air feeding part and at a part near the wall surfaces of an inner flame cylinder 2, outer flame cylinder 3 and a lower red heating cylinder 4, where the gasified gas and air are mixed, the central part makes a nearly layered flow and a high concentration of gasified gas is generated. Therefore, when the gas ascends up to the secondary combustion part, it may produce a dispersed combustion and a yellow flame. However, the gas flow ascending in a substantial laminated flow through the air port 7 promotes a mixing action with air and the gasified gas under a low eddy current produced by the projected part and at the same time air is supplied to the central part of the combustion chamber A having a high concentration of gasified gas. Thereby, a premixing rate of gasified gas and air is improved and a production of blue flame at the secondary combustion part is promoted.

Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a transmitting ad receiving module which is easily manufactured and suppresses electric crosstalk from a semiconductor laser(LD) to an end face incident type photodiode(PD). SOLUTION: In a flat surface mounting type transmitting and receiving module in which an LD is arranged closely to a PD, a receiving LSI 13 of an optical signal the rear surface of which the PD 21 is mounted is mounted on an Si substrate 20 wherein a difference 11 is level is formed in the end face of an optical waveguide 22 by solder bumps 25 so that the PD is housed. Since the PD is electrically separated from the LD which is adjacently arranged on the same Si substrate by the gap with the Si substrate owing to the difference 11 in level, electric crosstalk from the LD to the PD is suppressed.
