Abstract: PURPOSE:To provide an elevating/lowering type pitcher's mound with easy maintenance and low cost of maintenance by supplying compressed air to an airtight chamber by an air supply device and elevating the pitcher's mound from a recessed part by pushing up a movable base in the airtight chamber formed with a film. CONSTITUTION:The recessed part 3 is provided on a ground 1, and the movable base 5 is arranged in the recessed part 3 so as to be elevated freely in parallel with a bottom 7. The pitcher's mound is provided on the movable base 5 by using soil 9, and the airtight chamber 17 is formed with a cylindrical film 15 between the bottom 7 of the recessed part 3 and the movable base 5. One end of an air pipe 25 protruding over the bottom 7 is opened in the inside of the airtight chamber 17, and the air supply device is connected to the other end of the air pipe 25. When the compressed air is supplied from the air supply device to the airtight chamber 17, the cylindrical film 15 is stretched and the airtight chamber 17 pushes up the movable base 5, which elevates the pitcher's mound. A control lever is turned in a state in which the pitcher's mound is elevated to the highest position, and a wire 33 is loosened, and a pole 27 is erected upright by the force of a spring.

Title: Image forming device
Inventor: NAGASE YUKIO
IPC: G03G15/09
Filed: 1993-07-08
Abstract: PURPOSE:To obtain a high-quality image without fogging by specifying the length of a magnetic brush for two-component developer when it is judged that there is no a latent image carrier. CONSTITUTION:The magnetic brush is formed of a magnetic pole S1 proximate to a photoreceptor drum 1 out of the plural magnetic poles and the length H of the magnetic brush when it is judged that there is not the drum 1 is set so as to be within 300% of a proximate distance between the drum 1 and a developing sleeve 11. When proportion between the napping height H of developer and an S/D gap being a gap between the drum 1 and the sleeve 11 becomes <=300%, fogging quantity is remarkably reduced. When it becomes <=250%, the fogging hardly occurs. That means, the fogging quantity can be remarkably reduced in comparison with a developing system by a magnetic brush for two- component developer provided with toner and magnetic carrier by remarkably thinning the developer including the napping part thereof.

Title: Sewing control apparatus of sewing machine
Inventor: WATANABE KIMIO
IPC: D05B25/00
Filed: 1987-07-31
Abstract: PURPOSE: To improve the sewing skill of each operator and to improve the productivity of a sewing machine by displaying the operation condition of the sewing machine during sewing work in an operation graph and displaying the end time of a repetitive work process shared by the operator. CONSTITUTION: After initializing a setting part, a prescribed numerical value is inputted to setting input parts 22 and 26-29 and an operation recorder 35 is turned on. When the main power source of the sewing machine 1 is turned on and the operator starts the sewing work, by turning a foot pedal on by the operator, a main shaft is rotated, the output signals of an F/V conversion circuit (sewing speed detection means) 4 are obtained and the operation graph as indicated in a diagram for instance is plotted. In the operation graph, the operation conditions when an expert operator A and an operator B inexperienced in the work respectively drive the sewing machine to which this device is mounted are compared and it is discriminated at a glance that the sewing work time of one process is faster by Δt for the operator A.  The cause is that the operator B temporarily stops at a point (a) and a point (b) in the graph and also it is recognized that the operator B has the habit of stepping on the foot pedal only 'a little' at first like the point (c) and then continuing sewing.

Title: Printing head
Inventor: HAMAMOTO SHINICHI
IPC: B41J2/275
Filed: 1992-07-21
Abstract: PURPOSE:To shorten the forming time of a residual film, to equalize film thickness and to stabilize the return operation of an armature by coating the armature opposed surface of a yoke or the yoke opposed section of an armature with an epoxy resin through screen printing. CONSTITUTION:The end face oppositely faced to an armature 4 of a yoke 1 is coated with an epoxy resin film 2 through screen printing. Consequently, the adhesion of the armature 4 and the yoke 1 and the no-return of the armature 4 are prevented because the epoxy resin film 2 is interposed between the armature 4 and the yoke 1 when the armature 4 is attracted by the yoke 1 by constituting a printing head in this manner. Since the yoke 1 is coated with the epoxy resin 2 through screen printing, workhours for coating may be shortened, and the thickness of a coated film is equalized, thus stabilizing the return operation of the armature 4.

Title: Treatment of semiconductor substrate
Inventor: HAYAFUJI TAKANORI
IPC: H01L21/324
Filed: 1994-07-26
Abstract: PURPOSE:To quickly remove crystal defects such as stacking faults from a semiconductor substrate without creating surface roughness or contamination on the semiconductor substrate. CONSTITUTION:A semiconductor substrate having silicon as main component is heat treated within the atmosphere of a molecular gas containing N and H as constituent elements. If a silicon oxide film does not exist (curve B) on the surface of a semiconductor substrate, then the stacking faults are rapidly shrunk as the partial pressures of N and H increase compared to the case where a silicon oxide film is present on the surface of the semiconductor substrate (curve A). Moreover, the atmosphere for heat treatment is a molecular gas state so that there will be no occurrence of new crystal defects due to plasma damages or the like.

Title: Image reader
Inventor: NONOYAMA HIROSHI
IPC: H04N1/028
Filed: 1994-07-26
Abstract: PURPOSE:To obtain a color image excellent in the resolution independently of a temperature of an original around the read position by using a filter to shut off a luminous flux reflected at points other than the original read position. CONSTITUTION:Cylindrical light sources 21-23 having each spectral radiation characteristic of R, G, B are succeedingly subject to blink and lighting drive to emit the light an original read position 11 at an upper side of an original platen 10 with which a color original 1 is in press contact. Then the image of the light reflected at the position 11 and passing between filters 41, 42 is formed to a light receiving face of a photoelectric conversion element 6 through a lens 5. The element 6 converts the luminous intensity of the image formed on the light receiving face by the light sources 21-23 of the light source 2 subject to sequentially blink drive into a signal. Then the filters 41, 42 shut the luminous flux reflected in other points than the read position 11 thereby sufficiently interrupting the undesired reflected light from the original 1 and a color image with excellent resolution is obtained independently of the density of the original around the read position 11.
