Title: Powder feeder
Inventor: KATO KAZUMICHI
IPC: B65G27/32
Filed: 1999-12-14
Abstract: PROBLEM TO BE SOLVED: To feed a powder at a high accuracy, without greatly dropping the powder feed rate. SOLUTION: The powder feeder feeds an exciting current involving an asymmetric waveform to a voice coil motor 2 to shake a trough 4 enough to drop and feed the powder 6 such that a mass detector 7 detects the mass of the powder 6 dropped from the trough 4, a subtractor 8 obtains the deviation of the detected value from a set value, and if the deviation reduces below the set value, a compensator 20 controls a waveform controller 22, etc., so as to intermittently output current instructions involving asymmetric waveforms.

Title: Image forming apparatus
Inventor: TAKANUMA KOUJI
IPC: H04N1/00
Filed: 1998-12-14
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of an increase in the burden of a cleaning section and the degradation in productivity even in the case of a cover mode by excluding the cover output in the cover mode from a count number of sheets for measurement of reference pattern forming intervals. SOLUTION: This apparatus has a function to hold prescribed paper into the tops of respective sections in the case of copying of the plural parts of plural sheets of originals. For example, the paper for copying an ordinary image is set in the first stage of a paper feed cassette and the paper for the cover is set in a manual insertion feed section 22 and before the ordinary image is outputted, the paper for the cover is outputted from the manual insertion feed section 22. When the cover mode is used, the reference pattern formation intervals are made shorter by as much as the number of sheets of the cover and the burden to the cleaning section is increased.  The number of sheets of the display output considered to be low in an image ratio in the case of outputting of the cover at the time of the cover mode is, thereupon, precluded from the count number of sheets for the measurement of the reference pattern forming intervals. As a result, the reference pattern forming intervals are made longer and the increase in the burden on the cleaning section is prevented.

Title: Controlling method of length of parison in blow molder
Inventor: NOGUCHI TOKUJI
IPC: B29B11/10
Filed: 1991-12-27
Abstract: PURPOSE:To highly accurately control the length of parison and consequently enhance the accuracy of the wall thickness of a product by a method wherein the rotational frequency of a screw is controlled on the basis of the difference between the length of the extruded parison and the target length under the condition that the relationship between the rotational frequency of the screw of an extruder and the length of parison to be extruded is obtained in advance. CONSTITUTION:By obtaining the difference (t) between the time required by parison for being cut with a cutting device and the time required by the parison for passing through a photoelectric tube, which is provided below the die head of an extruder (or light exclusion time by parison), the value equivalent to the length of the parison can be set. There is a proportional relationship between 1/t and the rotational frequency N of the parison. By changing the rotational frequency by DELTAN to the deviation DELTAt of the light exclusion time, the target length of the parison can be ensured. At this time, the scattering of the length of the parison (or light exclusion time (t)) in the comparatively short period of time (or standard deviation (sigma)) is calculated so as to set a dead zone (3sigma). When the difference of the light exclusion time by parison falls out of the dead zone, the rotational frequency N of the screw is preferably corrected.

Title: Luminaire for ceiling
Inventor: SUGAYA YOSHINORI
IPC: F21V29/00
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To provide a luminaire for ceiling so designed that a luminaire body can easily be installed and removed without removing a heat insulating plate. SOLUTION: This luminaire includes a rotating support seat 38 pivotally attached to a position (hole) 28 of a luminaire body 20 near its outer periphery to support a heating point-light source 32 and a heat insulating plate 30 in such a manner that they are both freely movable. The movable range of the rotating support seat 38 is determined so that the heating point light source 32 and the heat insulating plate 30 retreat to positions where they do not obstruct the work of securing the body 20 to a luminaire mounting seat 10. The rotating support seat 38 is provided with a phase control part 36 which, in a normal rotation phase, permits mounting of a translucent cover 40 on the body 20 and which, in rotation phases that are not normal, stops mounting of the cover 40.  The body 20 is installed or removed by appropriately rotating the heating point light source 32 and the heat insulating plate 30 around the rotating support seat 38. Although there is the fear that the translucent cover 40 is installed and used while the heating point light source 32 and the heat insulating plate 30 are left in a phase that is not normal, it is solved by properly controlling mounting of the translucent cove 40 by use of the phase control part 36.

Title: Method and device for removing foreign matter
Inventor: OKADA MASASHI
IPC: B23K26/064
Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To enable irradiation of a laser beam without lowering its intensity by filling the space, through which the pulsed laser beam propagates before reaching the material to be processed, with a gas containing no vapor when foreign matters deposited on a material to be processed are removed through the irradiation of a pulsed laser with a wave length absorbable in water after a water film is formed on the material.

A cooling stage 8 cools the substrate 7, depositing water droplets on the surface of the substrate. A gas containing no vapor is supplied from a cylinder 5 to the laser beam introducing tube 3. The pulsed laser beam 2 is emitted to the substrate 7 with the intensity unlowered, and absorbed in the water droplets on the surface of the substrate, the droplets rapidly evaporate, simultaneouly separating and removing the foreign matters deposited on the substrate 7 from its surface. The laser beam introducing tube 3 is preferably evacuated inside.

Title: Blowing air amount regulating device of air blower
Inventor: AKAMATSU YUKIHIKO
IPC: F04D27/00
Filed: 1991-12-09
Abstract: PURPOSE:To regulate blowing air amount in a wide range from the maximum to the minimum freely by covering the outer peripheral part of a runner with a damper at prescribed intervals in the horizontal direction, and sliding the damper in the lateral direction. CONSTITUTION:When the motor of an air blower accommodated in a fan casing is driven to rotate a runner 12, air is sucked into a central area part 12b through an inlet cone 13, and then discharged outside the runner 12 from a clearance between respective fins 12a. When the bolt 42 of an operation mechanism 4 is rotated, the damper 2 travels in the right direction as illustrated, because respective nuts which are engaged with the bolt 42 are fixed at a damper 2 so as not to rotate. As a result, the damper 2 covers the air discharge part of the runner 12, and the area of the air discharge part, that is, the discharged air amount and blowing air amount are reduced in proportion to a covering distance. It is thus possible to regulate blowing air amount from the maximum 100% to the minimum 0% freely by the lateral reciprocating linear movement of the damper 2 by the operation mechanism 4.
