Title: Manufacture of semiconductor device
Inventor: NISHIZAWA MASATO
IPC: H01L21/31
Filed: 1988-02-16
Abstract: PURPOSE:To reduce the temperature for flattening, and enable forming a shallow junction for miniaturization by using a stable interlayer insulating film as compared with a BPSG film by a method wherein a high temperature CVD oxide film is formed on a lower layer wiring, and an interlayer insulating film is formed by spreading insulating material dissolved in solvent on the CVD film, and heating is performed. CONSTITUTION:A first layer 6 composed of a high temperature CVD oxide film is formed on a lower layer wiring 3; insulating material dissolved in solvent is spread on the first layer 6 and heated; a second layer 7 composed of an insulating film having a flat surface obtained by the above process is laminated; thereby forming at least a part of an interlayer insulating film. For example, a gate 3 is formed on a silicon substrate 1 via a gate oxide film 2, and a thermal oxide film 4 for element isolation use is formed; then a source.drain region 5 is formed; on the substrate, an SiO2 film 6 is formed by a high temperature CVD method at 600-800 deg.C; by a spin-on-glass method, the formation of coating film and curing are repeated twice; thereby, an insulating film 7 is buried in the step-difference part of the SiO2 film 6 surface, and a flattened surface is formed. If necessary, the surface is covered with an SiO2 film 8 as a third layer formed by a low temperature CVD method.

Title: Manufacture of semiconductor substrate
Inventor: ISHITANI AKIHIKO
IPC: H01L21/205
Filed: 1984-02-24
Abstract: PURPOSE:To obtain an silicon-on-insulator having a large area by forming the triple structure of magnesia spinel-SiO2-silicon, using an opening section in the structure as a seed and depositing a single crystal silicon film on the whole surface of a wafer in a homoepitaxial manner. CONSTITUTION:An epitaxial film 11 consisting of MgO.Al2O3 is grown on an Si single crystal substrate 10. When a wafer is thermally oxidized, oxygen diffuses to silicon through magnesia spinel, and SiO2 is formed between magnesia spinel and silicon. A striped pattern is formed to the wafer having obtained triple structure of magnesia spinel-SiO2-silicon. The wafer is charged to an epitaxial growth device, and silicon is deposited. Silicon is not deposited on magnesia spinel because a source gas SiH2Cl2 contains Cl at that time. The film 11 is grown selectively in an epitaxial manner while using silicon in opening sections as seeds. The whole surface is coated with a single crystal 13 in which there is no micro-twin of silicon.

Title: Spacer
Inventor: NISHIBORI KIMIKO
IPC: E04C5/20
Filed: 1995-02-22
Abstract: PURPOSE: To enable the simple and certain mounting on mild steel bars using weak force without dropping the function as a spacer. CONSTITUTION: The mild steel bar receiving holes S of a pair of mild steel bar inserting recepracles 4, 4 arranged tapered directed inward from the top of a mild steel bar reception part 3 are formed o that their diameters enlarge gradually toward the front extremity. It is preferable that the wall thickness is lessened, for example at the foremost extremity, to give variation in the thickness of the reception part 3 while the wall thickness of the tail part is left unchanged. Wings 6, 6 are formed at the oversurface base ends of a pair of bar hitching parts 5. 5 furnished at the front faces of arms 2. 2.  These wings 6, 6 should preferably be installed parallel with the arms 2 so that they contact with a certain necessary part, at least the oversurface of crosswise mild steel bars, which will effectively hinder a spacer installed on the crosswise bars from swinging in the directions to the left and right.

Title: Shaft inserting device
Inventor: NARITA YOSUKE
IPC: B23P19/02
Filed: 1993-02-23
Abstract: PURPOSE:To insert a shaft positively into a bearing hole by holding the attitude of a member with the bearing hole in the neutral position, to the required inclined attitude so as to make the respective axes of the shaft and bearing hole coincide with each other on the way of the shaft being inserted into the bearing hole. CONSTITUTION:At the time of inserting a locker arm shaft PS into the bearing hole EH of a cam holder EF1, the holding base 10d of the cam holder EF1 is oscillatingly supported by a rotating shaft 10h offset downward. The holding base 10d is then brought into butt-contact with a stopper 10j by a spring 10i and turned backward in the insert direction so as to incline the axis of the bearing hole EH onto the offset side of the rotating shaft 10h. At the insertion starting time, the axis of the bearing hole EH does not thereby coincide with the axis of the locker arm shaft PS so as to impede smooth insertion. However, both axes coincide on the way of the attitude of the cam holer EF1 being raised against the spring 10i, so that the locker arm shaft PS can be positively inserted into the bearing hole EH.

Abstract: PURPOSE:To confirm the amount of liquid accurately at low cost by confirming the presence position of an air layer by utilizing the properties of the propagation speed and reflection of an ultrasonic wave. CONSTITUTION:When a sample 50 is sucked up, a pipette contains the sample 50, the air layer (a), and wash water W in order from its tip. Then, a control signal is outputted from a control part 8 to a driving circuit 5, and then a bracket 4 begins to move down and a transmitter 2 sends out an ultrasonic wave, so that the ultrasonic wave passing through the air layer (a) is caught by a receiver 3 through the pipette P. Then, the ultrasonic wave is amplified and detected 6, A/D-converted 7, and then inputted to the control part 8. Then, the control part 8 calculates the time when the ultrasonic wave is sent out of the transmitter 2 and the time when the wave is received by the receiver 3 to confirm the part of the air layer (a).

IPC: G03G21/20
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To easily estimate the temperature range of a pressure roller and to obtain a required fixing ratio and a small curling quantity, even if the temp. of the pressure roller is low or high by controlling a heat source in accordance with the count value of a job counter, with a temperature control means. SOLUTION: The temp. of a heating roller 12 is detected by a temperature detecting means 15a, the heat source 13 is controlled by the temperature control means 50a and a recording medium to which a developer is transferred from a latent image carrying member is pressed on the heating roller 12 by the pressure roller 14. At this time, a start-up for starting printing from a printing standby state where the latent image carrying member is stopped is executed by the job counter 70 and an operation from the execution of the printing to the stopping of the latent image carrying member is counted as one job. Then, the temperature control means 50a controls the heat source 13 in accordance with the count value of the job counter 70.  Thus, the temperature range of the pressure roller 14 can be easily estimated and the required fixing ratio and the small curling quantity can be obtained even if the temp. of the pressure roller 14 is low or high.

Title: Valve positioning device
Inventor: HANSU DEI BAUMAN
IPC: F16K31/44
Filed: 1989-02-15
Abstract: PURPOSE: To prevent the corrosion of actuating parts from occurring and also to make a speed of response variable by installing a recessed expanding bore in the central part of a valve element, and intercommunicating an outlet port and an upper case inside to each other, while installing an adjusting screw in this intercommunicating passage. CONSTITUTION: A recessed expanding bore 33 is installed in the central part of a valve element 10, and an outlet port 5 and the inside of an upper case 14 are intercommunicated to each other via two intercommunicating passages 34 and 35, and then an adjusting screw 36 is installed in both these passage 34 and 35. With this constitution, since compressed air out of the outlet port 5 sweeps away the inside of the upper case 14, corrosion in actuating parts is thus preventable from occurring. Furthermore, an exhaust air flow rate is adjustable by the adjusting screw 36, so that a speed of response can be made variable in this way.
