Title: Method and device for identifying scanning direction of optical scanner
Inventor: OGIWARA MASAO
IPC: G06F3/039
Filed: 1989-07-19
Abstract: PURPOSE:To identify a scanning direction by using a pad where optical reflection zones in which a reflectance gradually increases when scanning is executed in one direction and the reflectance gradually decreases when scanning is executed in an opposite direction are repeatedly arranged in parallel. CONSTITUTION:The optical reflection zones 1A in which the red reflectance gradually increases when scanning is executed in one direction and it gradually decreases when scanning is executed in the opposite direction are repeatedly arranged in warp streak for the pad 1. A red light-emitting part 5a scans the pad 1 in a right direction and a red light-receiving part 7a receives light so as to obtain a sawtooth output signal 6. Then, an ATLC circuit 24 obtains a reference signal 23 and a comparator 31 compares the output signal 6 with the reference signal 23. Then, the pulse wave 29 of a positive polarity can be obtained in a place where the levels of both signals are inverted. Since the polarity of the pulse wave 29 is positive, that the scanning direction is the right direction can be identified. Next, the pulse wave 29 of the negative polarity is obtained when scanning is executed in a left direction and that the scanning direction is the left direction is identified.

Abstract: PURPOSE:To suppress reduction in the quantity of incident light so as to reduce a change in photocurrent due to an incident angle of the incident light, by providing a surface of a protection glass with processing which is used to diffuse the incident light on a surface of a photodetector unit. CONSTITUTION:A surface of a protection glass 2 facing a photodetector unit 11 is sandblasted as shown in a symbol 3. One part of light IN incident to a light-receiving element 1 is reflected on the surface of the protection glass, and the other part is transmitted there to attain to the sandblasted surface 3. The incident light attaining to the sandblasted surface 3 is diffused on this surface to become diffusion light DF, and the ligh DF is made incident to the light receiving element unit 11. Photoelectric conversion is performed in the photodetector unit 11 by the incident diffusion light DF, so that photocurrent is generated according to intensity of the incident light IN, that is, the intensity of the diffusion light DF. Since almost all of the diffusion light DF is made incident to the surface of the photodetector unit 11, the sufficient quantity of light can be given to the photodetector unit 11.

Title: Medium for stocking bacterial strain
Inventor: KAWABATA AKIHIRO
IPC: C12N1/04
Filed: 1986-08-08
Abstract: PURPOSE:To enable the stocking of plural kinds of different bacteria such as aerobic bacteria and anaerobic bacteria in single medium, by adding charcoal to a medium. CONSTITUTION:A medium for the stocking of plural kinds of different bacteria is added with >=5wt% charcoal. The charcoal is especially preferably a bran charcoal produced by thermally evaporating water from rice bran, because rice bran charcoal is resistant to form tar and contains minerals. The content of the charcoal in the medium should be >=5wt% since the objective effect cannot be attained at <5wt%. There is no particular upper limit in the content of charcoal and is properly selected according to the amount of the bacteria to be stocked. The amount of bacteria is preferably about 10<6>-10<8> cells/1g of the medium for stocking in general. The amount exceeding 10<9> cells/1g of the medium is undesirable because of high stocking cost.

Title: Production of toner
Inventor: NOMURA MINORU
IPC: G03G9/087
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To considerably increase the efficiency of a distillation step and to considerably shorten the distillation time by adding a defoaming agent to a liquid medium in distillation. SOLUTION: Since the removal of an organic solvent is practically and preferably carried out in distillation by vacuum distillation but a long time is needed owing to foaming in distillation, a defoaming agent is added to a liquid medium in distillation. Foaming is suppressed and the distillation time is considerably shortened while keeping physical properties of the resulting toner good. The defoaming agent may be a commercially available one but a silicone defoaming agent which is readily dispersible or soluble in an aqueous medium is appropriately used because even a small amount of the defoaming agent produces a high foaming suppressing effect.  The amount of the defoaming agent added is not particularly limited if foaming is suppressed to such a degree that smooth vacuum distillation can be carried out but the amount is usually 1 to 10,000 ppm, preferably 1 to 1,000 ppm, further preferably 1 to 100 ppm based on the amount of the liquid medium after granulation.

Also, a blind 2 covers the whole visual field except the screen. In such a way, an involuntary motion for allowing the screen 23 and the opening part 1 to coincide with each other is solicited, and an inclination of an observer's head can be prevented. Also, by providing the blind 2, an external light from other part than the display is cut off, and brightness of an image is improved relatively.

Title: Data reception control method for print controller
Inventor: KURASHINA MANABU
IPC: B41J5/30
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To shorten the overall processing time by controlling the use capacity of a reception data storage device so that the volume of reception data and the use capacity of the reception data storage device match with each other. SOLUTION: Each time reception data is received from a data reception program 13, a data analysis program 14 compares contents of a storage device 11, where the total volume of data transmitted from a host device 9 is stored, and those of a storage device 12 where the volume of data received by this time is stored. When the volume of unreceived data is smaller than the use capacity of a reception data storage device 16, a data analysis program 14 communicates data including the use capacity indication of the reception data storage device 16 to a data reception program 13 so that the use capacity of the reception data storage device 16 matches the capacity of unreceived data.  Since the data reception program 13 makes the use capacity of the reception data storage device 16 and the volume of reception data match with each other by this communication including the use capacity indication of the reception data storage device 16, the time-out detection time doesn't occur.

Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To attain a simple and reliable initialization in a short time by giving a longitudinal direction of a linear light beam image an angle in the radial direction or the normal direction of an optical disk. SOLUTION: When the angle between the longitudinal direction of a stripe like beam image and a track is defined θ, and a width of its image is W, and a length is I, the equivalent length I' of this image in the disk radial direction becomes I'=Isinθ, and the width W' in the track direction becomes W'=W/sinθ. In such a manner, by giving the longitudinal direction of the stripe like beam image, the angle for the track, beam irradiation range and irradiation time per one revolution of a disk are set without reducing the peak intensity of the beam image.
