Title: Washing apparatus
Inventor: NOBUHARA YOSHIO
IPC: B65G49/02
Filed: 1989-02-20
Abstract: PURPOSE:To realize the automating of substrate washing by installing a substrate suspending apparatus on the substrate carrying-in side of a tank, installing a substrate detaching apparatus on the substrate carrying-out side of a washing part, and installing direction converting apparatuses in front and rear of said suspending apparatus and detaching apparatus, respectively. CONSTITUTION:In front of a substrate suspending apparatus, the direction of a lift 8 is changed so as to be able to suspend a substrate 17 by a direction converting apparatus 35a. The substrate 17 carried by a roller conveyer is arranged at a suspension position by a stopper and a correcting apparatus, and suspended by the lift 8 which has been turned.

Title: Exciting method for demagnetizing electro permanent magnetic chuck
Inventor: IKEHARA NAOHARU
IPC: B23Q3/15
Filed: 1984-03-02
Abstract: PURPOSE:To facilitate removal of work from magnetic chuck by performing counter-excitation of an electromagnetic coil to release a work thereafter supplying weak current for performing positive excitation and demagnetizing the work. CONSTITUTION:A work 9 can be removed by reversing the polarity of a polarity inverting magnet 6b, but the magnetic field produced by a coil 8 through reverse excitation will function onto the work 9 and the flux produced not through the magnets 6a, 6b but through the remanence of the work 9 will exist in the magnetic chuck even after blocking of current. Consequently, the work 9 is adsorbed to the face plate of the magnetic chuck by the internally produced flux even if it is not applied externally. In order to eliminate the flux produced by the remanence, weak magnetization of such polarity as shown in the parenthesis may be performed to produce the flux shown by the dashed line, and since said flux is in the same direction as the positive excitation or when the magnetic chuck is turned on, the magnetic coil 8 may be excited positive.

Title: Preparation of different kind of polypeptide expressed in fibrous fungus
Inventor: RANDEII EMU BAAKAA
IPC: C07K19/00
Filed: 1996-02-27
Abstract: Novel vectors are disclosed for expressing and secreting heterologous polypeptides from filamentous fungi. Such vectors are used in novel processes to express and secrete such heterologous polypeptides. The vectors used for transforming a filamentous fungus to express and secrete a heterologous polypeptide include a DNA sequence encoding a heterologous polypeptide and a DNA sequence encoding a signal sequence which is functional in a secretory system in a given filamentous fungus and which is operably linked to the sequence encoding the heterologous polypeptide. Such signal sequences may be the signal sequence normally associated with the heterologous polypeptides or may be derived from other sources. The vector may also contain DNA sequences encoding a promoter sequence which is functionally recognized by the filamentous fungus and which is operably linked to the DNA sequence encoding the signal sequence. Preferably functional polyadenylation sequences are operably linked to the 3' terminus of the DNA sequence encoding the heterologous polypeptides. Each of the above described vectors are used in novel processes to transform a filamentous fungus wherein the DNA sequences encoding the signal sequence and heterologous polypeptide are expressed. The thus synthesized polypeptide is thereafter secreted from the filamentous fungus.

Title: Apparatus for selecting grain
Inventor: TOKI HARUMITSU
IPC: G01N21/85
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To stabilize decision of a grain type and to improve a grain type selecting accuracy by detecting light quantities of wavelengths of specific two types from a transmitted light quantity of the grain, comparing its ratio value with that previously set in response to a grain type and deciding the grain type. SOLUTION: Grains are irradiated with an inspection light, and light quantities of wavelengths R, G and G of three types are detected from transmitted light quantities of the grains. Then, a ratio value R/B of the light quantity of the wavelength R to that of the wavelength B of two types of largely different ratio values according to the grain types is calculated by a CPU. The ratio value (reference value) R/B of the wavelength R to the wavelength B previously set in response to the grain type is compared with the calculated ratio value R/B, and the grain types such as milled rice, dehulled rice, glutinous rice or the like is, for example, decided. Thus, even in the case of change of irradiating amount due to deterioration of a light emitting unit, the ratio R/B of the light quantities is not changed, and hence the grain type can be stably decided.

Title: Method for improving corrorsion resistance of welding part of through tube to container
Inventor: TANAKA ATSUSHI
IPC: B23K20/00
Filed: 1991-03-06
Abstract: PURPOSE:To improve the repair and soundness of prevention and so forth of leakage in the neighborhood of a welded part by forming a corrorsion-resisting clad layer on the inside surface of a through tube to a container. CONSTITUTION:The inside surface of the through tube 3 to the container is coated with sintering metallic powder in a coating range beyond the range of the welded part 5. A heating means is inserted suitably into the inner part of the through tube 3 to the container, a tube position coated with the sintering metallic powder is heated in helium atmosphere, a clad welding wherein the sintering metallic powder is melted is performed to form a corrorsion-resisting metallic clad layer 8. When a defect part has been generated on the tube wall in the neighborhood of the welded part 5, the tube wall is blocked in the thickness direction and when leakage phenomenon is generated, the leakage is stopped. The range of the blockage is wider than the welded part 5 and since the corrorsion-resisting metallic clad layer 8 is interleaved on the inside surface of the tube wall, corrorsion resistance is improved and improvement of corrorsion resistance is expected to the neighborhood of the welded part 5 on the outside surface of the tube wall, too.

Title: Constant speed drive unit for automobile
Inventor: HAYAMA MAMORU
IPC: F02D41/14
Filed: 1986-02-25
Abstract: PURPOSE:To give a driver a set feeling that his car enters a range of constant speed control and thereby make safety driving achievable, by installing such a device that controls an actual running speed so as to be maintained in the setting running speed, and also installing an accelerating control part making the actual running speed higher than the setting running speed when it is inputted. CONSTITUTION:When the setting running speed is set, an automobile enters a constant speed controlling state which maintains the speed. At this time, an accelerating control part 4 outputs a command, which increases a fuel supply to an engine, to a fuel supply regulating device 3. This controls the engine so as to become a higher running speed than the setting running speed, whereby speed-up control takes place as long as the preset time. A driver feels accelera tion owing to the occurrence of the acceleration caused by this speed-up control. Therefore, the driver may free his mind from anxiety that his automobile might not enter the constant speed driving control, so that he can correspond to the drive with ample room.
