Filed: 1989-05-20
Abstract: PURPOSE:To enable the relative positions between exposed patterns and not yet exposed patterns of an exposure substrate to be kept at optimum values regardless of the changes in the pattern sizes during exposure process by a method wherein the position correcting values are calculated by the position alignment widths to correct the exposed pattern positions. CONSTITUTION:The pattern widths of alignment marks 12-15 on an exposure substrate in x and y directions are measured to calculate the deviation of the width in the respective directions from the designed values 8-11 (DELTAWx, DELTAWy)=(Wx-Wox, Wy-Woy). Then, the pattern exposure positions are deviated by DELTAx=fx(DELTAWx, DELTAWy), DELTAy=fy(DELTAWx, DELTAWy) using the functions fx, fy where fxnot equal to 0, fynot equal to 0, and either of fx or fy is not a constant. That is, the deviation of exposed pattern sizes from the designed values is calculated by measuring the widths of alignment marks so that the exposure positions of the patterns may be deviat ed from the designed values. Through these procedures, the relative positions between the exposed patterns 3, 4 and not yet exposed patterns can be kept at the optimum values.

CONSTITUTION:When a vision sensor 60 is not driven, it is prevented that exhaust gas and dust, etc. adhere to a lens 62, by closing an opening part. Also, by driving a protecting device 63 for an optical lens, pressure air from a supply source 90 is brought to a pressure reduction by a throttle valve 96 after dust is removed by a filter 92, and low pressure air is led out to the shutter 68 side from duct lines 80a, 80b, and prevents dust, etc. from invading the inside of a cover member. When a motor is driven and a rotary driving axis is rotated, the shutter 68 is oscillated under a driving action of a cylinder 70 and the opening part is opened. Subsequently, the pressure air from a duct line 102s drives a changeover valve 94, and air of high pressure is jetted to the front in the axial direction of the lens 62 through the duct lines 80a, 80b.

Title: Piezoelectric microphone
Inventor: OBARA HIROSHI
IPC: H04R17/02
Filed: 1979-10-03
Abstract: PURPOSE:To make a piezoelectric microphone small-size, by using a high-polymer piezoelectric film as the diaphragm of the microphone to enlarge the electrostatic capacity as much as possible and by using no impedance converting circuit to connect the microphone to an amplifier directly. CONSTITUTION:In respect to the characteristic of the microphone used in small- size acoustic apparatus such as a cassetter tape recorder, it is found that the microphone can be used prectically if the low-band cut-off frequency is 1.5kHz approximately, and the lower limit of the electrostatic capacity of the diaphragm is set to 2nF. As the upper limit of the electrostatic capacity, 100nF is set. The reason why this value is set as the upper limit is because the area of the diaphragm is very large for 100nF or more and is disadvantageous to the use as a microphone. High- polymer piezoelectric films 1 and 1' are used as the diaphragm and are spread spherically through cushion material 3 over conductive frame body 2 having air duct 4. Frame body 2 is stored in shield case 6 through spacer 5. Then, diaphragm 1 can be connected to an amplifier directly.

Title: Deposition of photoresist
Inventor: YAMAZAKI KENZOU
IPC: H01L21/027
Filed: 1982-07-22
Abstract: PURPOSE:To obtain a uniform resist film with good reproducibility by adequately controlling duct absorption amount of the photoresist deposition chamber, removing the mist of photoresist and by controlling contained solvent before it is hardened. CONSTITUTION:A resist is dropped for a specified period from a nozzle 16 and it is then rotated 18 at the rate of 300-10,000rpm. In this case, a duct absorbing meter which is set for column of 10-30mm. absorbes the mist of resist in the initial rotation and also absorbes a certain degree the solvent contained in the resist 17 during rotation at a low speed. The rotation speed is changed to a high speed from a low speed, the absorbing meter is automatically set to water column of 0-10mm. at the time of obtaining a resist film 17 of the desired thickness. Ideally water column of 0mm. is desirable but the water column of 10mm. or lower is selected in order to remove bad smell. Under this condition, a uniform film thickness can be obtained owing to surface pressure and centrifugal force. Thereafter, amount of absorption is returned to a duct amount during a lower rotation speed. With such structure, uniform photoresist can be deposited on a semiconductor wafer 11 with very good reproducibility.

Title: Carbon-filament package
Inventor: SUGIURA MASAHIKO
IPC: D01F9/12
Filed: 1982-07-22
Abstract: PURPOSE:To obtain a package which has the improved filament releasing property because of possibility of neither shape deformation nor slip-off of single layer from a bobbin by winding-up a carbon filament in a specific apparent winding-up density onto a bobbin which has an outside diameter of a specific length or above and on which uneveness is formed. CONSTITUTION:The outside diameter of a bobbin 1 is set at 50mm. or more, so generation of fluff due to breakage of monofilament is prevented, obviating the bending in any severe curvature. Uneveness 2 for preventing slip-off of single layer by increasing the frictional force with carbon filament is formed on the surface of the bobbin 1. Onto the surface of said bobbin 1, a carbon filament 3 is wound-up in apparent winding-up density of 0.75-1.1g/cm<2>. Said apparent winding-up density means the value obtained by dividing the weight W(g) of the wound-up filament by the apparent volume of the filament. Therefore, the amount X of filament wound-up per surface area (cm<2>) of the bobbin 1 can be increased to about 3-8g., and a package which has an improved filament releasing property because of possibility of neither shape deformation nor slip-off of single layer from the bobbin 1 can be obtained.

Abstract: PURPOSE: To improve pressure resistance and heat insulation, by mounting reinforcing elastic bodies to fixed interval locations in the axis direction of an inner pipe.  
     CONSTITUTION: Bellows 11, which freely expand in the axis direction of a high temp resisting inner pipe 3 produced by inserting fibriform heat insulating materials 5 between a pressure resisting pipe 4 at the outside and the pipe 3 in a layered shape through metallic foils 6, are installed to an end surface of said inner pipe 3 by means of welding, etc. at a fixed interval. Consequently, the bellows 11 absorb thermal expansion due to the change of the inner pipe 3 into high temp while they function as reinforcing materials to pressure difference inside and outside the inner pipe 3, thus eliminating the need for an additional mechanism for considering temp change while preventing the deformation of the inner pipe 3, then somoothly distributing gas through a passage 2.
