Title: Film detection method by optical detection means for photograph processing machine
Inventor: EBARA TAKUSHI
IPC: G03B27/46
Filed: 1994-02-10
Abstract: PURPOSE:To obtain the film detection method which prevents an adjusting operation by man power from becoming troublesome and which prevents a malfunction from being generated by a method wherein the existence of a film is detected surely without using the film. CONSTITUTION:By the instruction of an electronic control circuit 10, a reterence setting voltage by a reference-voltage generation circuit 7 is set so as to have a prescribed margin degree more than an initial set value (a standard value). The driving current of a light-emitting element 1 is increased via a D/A conversion circuit 3 until the voltage becomes a new reference setting voltage. A constant-current circuit 4 is set to a constant value at a moment in which the output voltage of a photodetector 2 exceeds the reference setting voltage. After that, the reference setting voltage of the reference-voltage generation circuit 7 is returned to an original value. When the lightemitting element 1 is set so as to have the prescribed margin degree more than usual, the existence of a film can be detected surely without using the film even when an output is dropped due to a secular change.

Title: Waver carrier elevator apparatus
Inventor: SUWA YOSHIHIDE
IPC: H01L21/68
Filed: 1986-01-30
Abstract: PURPOSE:To prevent the attachment of dust from a lifting mechanism to a wafer, by providing a mounting stage of a wafer carrier at the uppermost part, providing a base body under the stage in a separated manner, thereby constituting an elevator main body, providing the lifting mechanism in the elevator beneath a carrier stage, and lifting and lowering the mechanism together so that the wafer does not face the lifting mechanism. CONSTITUTION:A conveyer 43 is moved based on an external command. When a wafer 3 at the lowest position is carried out, a motor 55 in a driving means 54 is immediately started. An elevator main body 31 begins to descend with a feed screw 45. Thus a wafer carrier 6 is also lowered. The next wafer 3 is detected by a detecting means 33 and the carrier is stopped. The elevator main body 31 is stopped under the state the next wafer is mounted on the conveyer. On the other hand, when the wafer carrier 6 is located at the lowest position and the carrier is vacant, the wafer carrier is lifted by only one pitch when the wafer 3 is carried in a supporting groove 2 at the uppermost stage. Thus the wafers 3 are sequentially accommodated. Therefore, the lifting mechanism is always located at the position lower than the wafer carrier and does not face the wafers in the wafer carrier. Thus the wafers are not exposed to dust of the lifting mechanism.

IPC: H01L21/265
Filed: 1990-01-25
Abstract: PURPOSE:To improve uniformity inside the surface of an implantation depth of high dose shallow ion implantation by making a parallel to a beam and strong magnetic field to act between a focusing and deflection system and a sample system. CONSTITUTION:By applying a strong magnetic field 12 being parallel to a beam between a focusing and deflection system 1 and a sample system 4, an ion beam 16 being incident with a certain angle to the magnetic field after passing through a focusing and deflection system 1 becomes spiral to reach a sample according to the Fleming's rule of a left hand. When an angle of incident on the magnetic field, speed of the ion beam 16 and the strength of the magnetic field 12 are changed, a beam diameter can be changed. The mag netic field 12 is controlled so as to be parallel to the beam by combining a magnetic field in the parallel direction and a magnetic field in the vertical direction to a beam line 2. Accordingly, an incident angle of ions to the sample can be freely controlled, further since ions perform spiral movement, the incident angle to the sample is reversed on both ends of a beam section. Thereby, uni formity in the surface of the implantation depth of a high dose and shallow implantation can be improved.

Title: Butterfly valve
Inventor: NAKANISHI MIKIMA
IPC: F16K1/22
Filed: 1984-02-01
Abstract: PURPOSE:To reduce dynamic torque by folding a valve body in convex to the upstream side while bending the vicinity of nozzle section such that the fluid is inverted toward upstream. CONSTITUTION:A valve body 11 is folded in convex to the upstream side at the point a approximately 1/2-1/3 of radius at the orifice 1 side. While the portion nearer to the nozzle side than the point B in the vicinity of nozzle section 2 is folded in convex toward the upstream side. The flow from the upstream collided against the valve body is branched at the point A into flow I going to the orifice 1 side and flow II going to the nozzle 2 side. Dynamic torque functioning in the direction to close the valve body is reduced by the flow I . While since the valve body is bent toward the upstream side at the point B, the flow II will function to open the valve body thus to reduce dynamic torque.

Title: Solid preparation containing ubidecarenone
Inventor: SUZUKI HIROYUKI
IPC: A61K9/20
Filed: 1981-02-10
Abstract: PURPOSE: To prepare the titled solid preparation capable of keeping the homogeneity even at a temperature higher than the melting point of ubidecarenone, and effective to hypertension, ischemic cardiopathy, etc., by using ubidecarenone, gelatine and a saccharide other than sucrose, as essential components.  
     CONSTITUTION: A composition containing ubidecarenone of formula (chemical name: 2,3-dimethoxy-5-methyl-6-decaprenylbenzoquinone), gelatin, and a saccharide other than sucrose (e.g. glucose, fructose, etc.) as essential components. Since ubidecarenone is yellow or orange crystalline powder having a melting point of about 48°C, the storage of a ubidecarenon-containing solid preparation in an environment having large temperature fluctuation causes the localization of ubidecarenone and formation of colored spots, which are undesirable in view of the appearance and the absorptivity of the preparation. The localization of ubidecarenone in a solid preparation can be prevented even at ≥50°C by adding gelatine and saccharide other than sucrose, which are available at low costs.
