Filed: 1980-08-25
Abstract: PURPOSE:To shorten a scanning stroke by using an image forming element having refracting power as a scanning light system, and by varying the height of an image of a fixed light source by moving the element in parallel to an original surface. CONSTITUTION:Light from a fixed light source 1a is made incident to an inner mirror lens 3a directly or after being reflected by a reflecting umbrella 2a, and then reflected by the inner mirror surface to form an image on an original surface 4. Light from a light source 1b, on the other hand, forms at slit image on the original surface 4 simplarly. When the lenses 3a and 3b are moved as shown by arrows in parallel to the original surface 4, the slit lighting areas scans on the original surface 4 in the same direction, but the scanning area is constant, so that the greater the magnification (m) is, the shorter the scanning strokes of the lens 3a and 3b are. Denoting the magnification (m) as l2/l1, the l1 or l2 is set small or large and the focal lengths of the lenses are set corresponding to the setting of the magnification. The slit area is projected on a photoreceptor 6.

IPC: G06F9/46
Filed: 1995-05-16
Abstract: PURPOSE: To attain a data-oriented inter-program communication and to improve the data communication efficiency between programs. CONSTITUTION: By providing a communication packet 15, i.e., a communication unit with a message code (e) which describes the communication purpose of the data elements included in the packet 15, a category ID (d) which describes the basic communication purpose, a data ID (d) which identifies the data elements, a data type ID (f) which identifies the data types of data elements, and a data area (h) of the data element itself that performs the communication, the data-oriented communication is attained.  Therefore, it is not required to individually structure the data for every message unlike the conventional message-oriented communication, the transmission/reception of data can be performed in a freer form, e.g. only the data elements that need the communication due to the change of their value are selectively transmitted and received, and the data communication efficiency is improved between programs.

Title: Balanced element selection method for balanced network
Inventor: MARUYAMA KAZUYOSHI
IPC: H04B3/03
Filed: 1989-05-11
Abstract: PURPOSE:To decrease the selection processing time by dividing plural balanced elements into balanced elements whose level is brought into a reference level or below and balanced elements whose level is not brought into a reference level, comparing an echo peak level detected at a receiver side with the reference level at a comparator. CONSTITUTION:Balanced elements of a balanced network 3 are divided into a group of balanced elements 4 whose level is brought into a reference level and the remaining balanced elements 5 whose level is not suppressed to a minimum level. Then an echo peak level detected by a receiver side is compared with a reference level at a comparator 6 and the result of comparison is inputted to a selection means 20. Then the selection means 20 selects the balanced elements whose level is brought into a reference level or below among the elements 4. When the element cannot be selected, the remaining balanced elements 5 are selected to bring the echo peak level to at least a required minimum value or below. That is, since level compared by the comparator 6 is only one reference level, the selection processing time is decreased.

After this, it is again charged by the first friction charging member 17 and is then supplied to the surface of a photosensitive drum 12 while the rate of supply is being defined, whereby the electrostatic latent image is turned to a visible image. Hence, the toner is sufficiently charged and the ground contamination by charging deficiency and the reproduction defect of the low contrast portions may be prevented.

Title: Water level sensor
Inventor: KUNO HIROSHI
IPC: G01F23/22
Filed: 1988-05-17
Abstract: PURPOSE:To enable detection of an upper limit of a water level positively, by inverting an inversion disc to a concave from a concave depending on a storage water level. CONSTITUTION:In a water level sensor as shown by Fig. (b), as a storage water level L lowers, a water level detecting surface 5b separates from water and when the temperature of an bimetal-structured inversion disc 6 exceeds a working temperature with a heat generating body 3, the disc 6 is turned into a convex. Then, a contact plate 2b is pushed up through a driving bar 6 to open a switch 2, entering a standby state. As a water level L rises to let the detecting surface 5b contact water, the detecting surface 5b and the disc 6 are cooled while the heat generating body 3 generates heat and as the temperature thereof falls below a working temperature, the disc 6 inverted to a concave as shown by Fig. (a) to open the switch 2, making transmission ready. This enables detection of an upper limit of a water level positively.

Filed: 1988-05-16
Abstract: PURPOSE:To provide a hot water feeding device which has high safety especially and has an increased life, by a method wherein a pump located in the middle of a conduit is operated in linkage with detection by a level sensor. CONSTITUTION:A level sensor 31 is formed such that a ball 34 is located in a communicating pipe 30 and a beam type sensor 35 is provided outside the communicating pipe 30. Through cut off of beams from the sensor 35 by means of the ball 34, the level is detected. A conduit 36 intercouples a tank 21 and a boiler 22, and a pump 37 is located in the middle thereof, so that water in the tank 21 can be forcibly fed to the boiler 22. When normal heating is effected after the feed of hot water and the generation of steam, upon a decrease in level in a space part 23 the level sensor 31 does not detect the ball 34. Thereby, a relay 45 works to cause the pump 37 to run, and water is fed to the space part 23 of the boiler 22 from the tank 21, so that a level is always kept at a specified value.
