Title: Image processor
Inventor: HASEBE MITSUO
IPC: G03G15/01
Filed: 1987-04-27
Abstract: PURPOSE:To improve the processing speed of an image processor and to reduce the cost of its processing circuit, by processing plural picture data to be printed on the same transfer paper by means of the same circuit in line sequence. CONSTITUTION:The rotation of a polygon motor is kept at a high speed in conformity to a data processing speed. In other words, writing with a laser beam is switched in the order of Bk (black)  C (cyan)  M (magenta)   Y (yellow)    k.... When such writing procedure is applied, the copying speed of an A-4 size paper becomes (60X25)/(210+40)=6(copies/min), if the speed is droped to 1/4 and the line speed is set at 25 mm/sec, and then, a paper interval is set at 40 mm. The copying speed of A-3 size paper becomes about 3(copies/min) which is twice as fast as the copying speed of a drum system. Therefore, such advantages that thick paper can be used, a full-page image can be copied, and can be used practically and, moreover, the line speed of 25 mm/sec produces less noise and consumes less power. In addition, copying operations at the line speed of 25 mm/sec can improve the reliability in scattering of toner, etc.

Title: Charger
Inventor: UMETSU KOJI
IPC: H01M10/44
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of capacity drop of a battery without deteriorating a secondary battery, at low cost by stopping charging or indicating the termination by the comparison between the voltage difference between the first voltage n power source side and the second voltage on secondary battery side at the time of breaking a changing current and the reference voltage. SOLUTION: A comparator 14 detects the voltage between charging current breaking switches 12 by comparing voltage difference VA between the output voltage V0 of the power source 13 at no load inputted into a positive input terminal and open circuits battery voltage VB with the reference voltage Ea of the reference power 15a inputted into a negative input terminal, and outputs a detection signal SD to a charging controller 17. The charging controller 17 judges that the charging is to be continued, if the detection signal SD is High, and indicates 'in charging' on an indicator 18. Then, if the detection signal SD is Low, it judges that the changing is to be stopped, and indicates 'charging stop' on the indicator 18, and stops charging. Hereby, full charged condition can be kept at all times, and the cost of a product can be reduced, and the reliability of charging can be raised.

Title: Computer system
Inventor: RITA EMU OBURAIEN
IPC: G06F1/32
Filed: 1995-04-27
Abstract: PURPOSE: To provide a computer system and a method to control a peripheral bus clock signal via a slave device to which a power saving device is applied. CONSTITUTION: When the system is reset, a BIOS boot code reads a content of a configuration registration MAXLAT in each substitutive bus master. The content of the register indicates a frequency of required access by a specific master to a peripheral bus 102. When the MAXLAT field of each master is read, the system sets a timer according to the MAXLAT value corresponding to a master requiring most frequent access to the peripheral bus. When the master requiring most frequent access to the peripheral bus specifies a maximum wait time, e.g. 2μs, the system sets the timer to start a cycle for each 1μs (a half of specified maximum wait time). When a power management unit 111 decides stop of the peripheral bus clock, the timer starts the cycle.

Abstract: PURPOSE:To improve the sealing properties of a metallic base with its configuration simplified as well as to make bearing stress uniform with no fastening stress concentration developed while being excellent in heat resistance, and thereby make the base usable for an object with rough surfaces by letting sealing agents be applied on the whole surfaces of the front and rear of the elastic metallic base in a flat shape having holes bored as required. CONSTITUTION:A gasket 1 includes 2 cylinder bores 2, a water hole 3, a bolt hole 4, an oil hole 5 and the like. A base 10 is made of an elastic metallic sheet with heat resistance, is desirable to be elastic while it is applied with primer 11 in order that sealing agents are sufficiently adheared onto the front and rear of the base 10, furthermore, sealing agents 12 excellent in gaseous sealing properties are coated over or stuck together with the upper layer of primer 11 so as to be adhered. When pressure is applied onto the upper sections of bearing stress agents 13 by the junction surface 18 of a cylinder head 15, force is exerted onto the base 10 downward, and pressure is simultaneously applied to on the side of a bearing stress agent 13b from the junction surface side 17 of a cylinder 16, bending moment is thereby incurred on the base 10. The bearing stress agents 13a and 13b are excellent in rubber elasticity, stress thereby will never be concentrated in the base 10 at all.

Filed: 1979-08-16
Abstract: PURPOSE: To enable to emit the ionized electron beam to the electron multiplier with efficiency, by constituting the unit with the ionized ribbon, network metal plate and electron multiplier.  
     CONSTITUTION: The neutral cesium atomic beam 3 from the atomic beam source is ionized at the ionized ribbon 10. Suitable potential difference is given to the ionized ribbon 10 and metal plate 11 to keep the relation of V 10 >V 11  for the respective potentials. Thus, ionized cesium atoms are attracted to the metal plate 11 low in potential and collected. Since the metal plate 11 is constituted in net, cesium atoms can pass through the plate 11 with efficiency. In this case, since the directivity of the atomic beam 3 ionized with uniform electric field produced to the plate 11, the atomic beam 3 can be radiated to the electron multiplier 13 with good efficiency.

Title: Interchangeable lens permitting automatic focusing
Inventor: ATSUTA RIICHI
IPC: G02B7/02
Filed: 1980-08-01
Abstract: PURPOSE:To solve problems to be caused by touching by hand or the like in operation by providing an effective protecting wall to the lower side part of an interchangeable lens to protect movable parts. CONSTITUTION:With an AF lens, manual focusing (MF) is accomplished by manually rotating a distance ring 6, and automatic focusing AF is accomplished by turning a pin 61 from camera body side. In either case, turning the ring 6 turns a helicoid ring 7 because 6a and 7a parts are held coupled. The ring 7 is moved by the helicoid effect between the ring 7 and a stationary member 2, and this turning moves a lens barrel 8 in an optical axis direction, whereby focusing is accomplished. The lower side 3b of an outside barrel 3 is extended so as to envelop the ring 6, thus preventing the ring 6 from being touched by the operator's hand or the like. Thereby, the problems to be caused by the touching of the operator's hand or the like are solved.
