Title: Formation of oxide film on semiconductor substrate
Inventor: SATO NORITADA
IPC: H01L31/09
Filed: 1985-07-17
Abstract: PURPOSE:To form a high-quality ultrathin oxide film on a semiconductor substrate surface by a method wherein the semiconductor substrate is placed in a quartz reaction tube and, after an oxidizing atmosphere is provided in the reaction tube, infrared rays are applied to induce reaction between the oxidizing atmosphere and the semiconductor substrate which is heated only on its surface. CONSTITUTION:Semiconductor substrates 5, for instance substrates made of P-type silicon with specific resistivity of 10kOMEGAcm or higher, which is to be subjected to a treatment, are put on a quartz boat 4 and, after being inserted into a reaction tube 3 placed in a heating furnace 1 and arranged, a quartz cap 6 is put on the reaction tube 3 and oxygen is introduced into the reaction tube 3 through this cap 6 and discharged from the other end of the tube 3 to provide an oxygen atmosphere in the reaction tube 3. In this condition, infrared rays are applied to the semiconductor substrates 5 to absorption heating. Most of these rays are transmitted through the quartz reaction tube 3 and the quartz boat 4 and hence only the semiconductor substrates 5 are subjected to absorption heating so that oxide films can be formed on the surfaces of the semiconductor substrates 5.

Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To use a micromodule as a surface mounting type package. SOLUTION: A micromodule M is used as a surface mounting type package to be mounted on an interconnected substrate 5. In a first example, a barrier 4 which stops the spreading out of solder is formed between the contact zone 1 of the micromodule M and the corresponding contact pad of the substrate 5. This micromodule M is designed so that the thickness (e) of solder at its boundary surface S can be maintained by means of a mechanical stopper device 7. In other (n) examples, the contact zone 1 is expanded in a tongue-like shape. Surface mounting pins can be formed by means of a warping function.

Title: Sucked air heating device for internal-combustion engine
Inventor: KATOU KEIGO
IPC: F02M31/135
Filed: 1981-10-05
Abstract: PURPOSE:To prevent PTC elements from being cracked while maintaining the heat generating properties thereof by a method wherein a plurality of relief spaces are provided on a part of the outer circumference of an electrode inserted into an outer cylinder in pressure contact with the latter so that the stresses generating at the time of press-fitting an inner cylinder within the electrode into the outer cylinder through the PTC elements are absorbed by the relief spaces. CONSTITUTION:A plurality of concave sections 90 are provided on the cylindrical outer circumference of the graphite electrode 29 of the sucked air heating device at predetermined intervals at positions corresponding to the PTC elements 33, respectively, that is, the positions corresponding to the plain side surfaces of the polygonal inner circumference 31 of the graphite electrode 29. Accordingly, when the electrode 29 is press-fitted into the outer cylinder 16, the spaces 91 are provided between the electrode 29 and the outer cylinder 16 in correspondence to the concave sections 90, respectively, and therefore, the press-fitting load applied on the electrode 29 is limited to the contact sections 29' between the electrode 29 and the outer cylinder 16 so that the press-fitting load applied on the PTC elements 33 through the electrode 29 decreases. As a consequence, even when the small thickness section 15a of the inner cylinder 15 warps inwardly at the time of press-fitting the inner cylinder 15 into the outer cylinder, there is no fear of the PTC elements 33 being cracked.

Title: Proximity switch
Inventor: KAMIYA FUMIO
IPC: H03K17/95
Filed: 1984-07-27
Abstract: PURPOSE:To attain quick gain control corresponding to an oscillation amplitude change by dividing an output of an oscillation circuit into two circuit sections for detecting signal and for adjusting gain at oscillation decrease so as to decrease the time constant for gain adjustment. CONSTITUTION:An output of an oscillation circuit 1 is divided into two circuits, a signal detection comparator circuit 20 and a comparator circuit 21 for gain adjustment at oscillation decrease in a high frequency oscillation type proximity switch, the circuits 20, 21 are incorporated respectively with a rectifier, smoothing capacitors C22, 23 are connected and the capacitance value of the C23 is selected smaller than the capacitance value of the C22. When an object approaches, the oscillating level of the oscillator 1 is lowered and reaches a reference voltage Vref1 of the circuit 20, then the circuit 20 gives an output signal to a comparator circuit 24, which detects it and gives an object detection signal to an output circuit 25. When the object approaches further, the oscillation level of the circuit 1 is lowered and reaches a reference voltage Vref2 of the circuit 21 or below, the circuit 2 controls the circuit 1 to adjust the gain of the circuit 1 thereby continuing the oscillation of the circuit 1. Since the time constant of the circuit 21 is small, the change in the oscillation amplitude is responded to quickly.

Title: Method and apparatus for oxidizing semiconductor device
Inventor: TAKAOKA MATSUO
IPC: H01L21/31
Filed: 1988-06-27
Abstract: PURPOSE:To form an excellent oxide film with a high thickness accuracy and a high reproducibility by a method wherein the total steam quantity of each steam generator is reduced and the steam quantity of each steam generator is made to be uniform. CONSTITUTION:Steam generators 2 and 3 generate steam intermittently and periodically while they keep certain delay times against a steam generator 1. The delay times, pure water supply periods and cycle times can be so determined as to make one of the steam generators generate steam at any instance in an oxidation process. With this method, the steam flow through a mixer 4 is not discontinued. With this constitution, as the time variation of the generated steam quantity can be reduced, the fluctuation of the steam quantity introduced into a process tube can be suppressed to 1/2-1/3 of the fluctuation of a conventional constitution. As a result, the difference between the thickness of an obtained oxide film and the designed thickness can be also suppressed to 1/2-1/3 of the difference of the conventional constitution, so that the controllability and reproducibility can be substantially improved.

Title: Light deffusive polarizing panel material
Inventor: HORIE YASUKIRI
IPC: G02F1/1335
Filed: 1988-06-27
Abstract: PURPOSE:To reduce the thickness and weight of an LCD by sticking a foamed polyester sheet having light diffusivity to one face of the base material of a polarizing plate by a transparent adhesive agent. CONSTITUTION:The light diffusive polarizing panel material 1 is cut to a required size to form the light diffusive polarizing panel 1'. The need for separately providing a light diffusive plate is eliminated if this panel is used in place of the conventional lower polarizing panel and light diffuse plate. Not only the man-hours of production is, therefore, decreased but also the loss of material layout is decreased and the production cost of the LCD is drastically reduced. In addition, this light diffusive polyester sheet is much thinner than the conventional light diffusive plate and has sufficiently uniform light diffusion performance; therefore, the thickness and weight of the LCD are reduced.

IPC: H01J9/14
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To provide a multipole mass filter which has high sensitivity for detecting ions and has preliminary and main electrodes of good productivity.
