Filed: 1989-09-18
Abstract: PURPOSE:To improve the processing capability by providing an input side line control section applying control of physical level and data link level to an input line and an output line, an output side line control section and a switching processing section and further internal transfer control section in addition. CONSTITUTION:The switching processing section 50 applies only the operation of fetching information from an input line control section 20 and the operation of processing a packet level with respect to the fetched information and the operation of internal transfer of the processed information to an output side line control section 40 is implemented by an internal transfer control section 70 independently of the operation of the switching processing section 50. Thus, the switching processing section 50 fetches the packet information coming from other input lines 11-1n to apply the processing of the packet level while the information processed by the internal transfer control section 70 is transferred from the input side line control section 20 to the output side line control section 40. That is, the processing in the switching processing section 50 and the transfer operation of the processed information are implemented in parallel. Thus, the load of the switching processing section 50 is relieved and the packet switching processing capability is enhanced.

IPC: G03G15/00
Filed: 1986-10-13
Abstract: PURPOSE:To control the sticking quantity of toner with the width dimension of a toner picture smoothing area so as to prevent a secondary fault, by forming the toner picture smoothing area by delaying the turning off timing of a destaticizing lamp from the turning off timing of an electrifier by a prescribed time. CONSTITUTION:When a toner picture smoothing area A, in which toner is stuck to a photosensitive body over its full width, is formed just before a copying machine is stopped after completion of copying operations, the toner picture smoothing area A is formed by delaying the turning off of a destaticizing lamp 6 from the turning off timing of an electrifier 5 by a prescribed time. Since the width dimension of the toner smoothing area A formed on the surface of the photosensitive body is controlled by means of the turning off timing of the electrifier 5 and destaticizing lamp 6 in such way, the quantity of the toner sticking to the toner picture smoothing area A can be controlled by means of the width dimension of the area A and the turning off timing of the drive of a developing device can also be set after the toner picture smoothing area A is formed. Therefore, occurrence of a secondary fault can be prevented.

Title: Loadage-measuring apparatus
Inventor: TOYABE KIMIO
IPC: B60P1/04
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To prevent a vehicle from running with an overload, by displaying that the vehicle loads over a maximum authorized carrying load in a manner to be visually recognizable from outside the vehicle. SOLUTION: It is estimated that a load is loaded when a dump truck 1 stopped for five minutes or longer. A load sensor 4 set to a chassis 2 measures a loadage of a platform 3. When the loadage exceeds a preliminarily stored maximum authorized carrying load, a controller 5 transmits an overload signal to a display device 6. While the display device 6 installed at a side face of a driver's seat of the dump truck 1 does not display anything normally, but the display device 6, when receiving the overload signal from the controller 5, displays characters of 'overload' in a manner to be visually recognizable from outside of the vehicle. Therefore, even if a driver is unaware of the overload, surrounding people notice his overload, preventing the driver from running the vehicle with the overload.

Title: Manufacture of semiconductor device
Inventor: SATO TOSHIHIKO
IPC: H01L21/20
Filed: 1990-09-11
Abstract: PURPOSE:To conduct the film-forming process and the coarsening process of crystal grains in the same process and to shorten the treatment time by conducting the coarsening process of crystal grains through pyrolysis by irradiation of a polycrystalline semiconductor layer with laser beam in a silane atmosphere while it is deposited by high-frequency sputtering. CONSTITUTION:First, a substrate 1 is overlaid with an insulating film 2, which is then irradiated with laser beams while a semiconductor layer 3 is deposited. This semiconductor layer 3 made of polycrystalline silicon is deposited by high- frequency magnetron sputtering in a silane atmosphere with a low temperature of the substrate 1. During deposition of polycrystaline silicon, crystals grow by laser beam and coarsen the grain diameter to uniformize the size of crystal grains 4. This enables achievement of cold post-treatment and suppression of thermal scattering. Deposition of polycrystalline silicon and irradiation with laser beam can be conducted in the same process; therefore, treatment can be made in a short time of 5-6hr with improved efficiency.

Title: Travel controller for travel vehicle
Inventor: TAJI HIROSHI
IPC: F16H59/02
Filed: 1990-09-11
Abstract: PURPOSE:To improve the qualities of travel and work and the feeling of travel, by arranging so that the response speed of a pump tilting cylinder may be changed to plural steps by conducting the selective changeover operation of a mode changeover valve between a forward/ backward changeover valve and the pump tilting cylinder. CONSTITUTION:When a switch 28 that operates a mode changeover valve 24 between a forward/backward valve 7 and a pump tilting cylinder 4 is made to be under an OFF condition, the valve 24 is in an open connection oil passage position. When a wheel loader conducts advance/retreat, pressure oil from a charging pump 5 acts upon the cylinder 4 through the valve 7 and the open connection oil passage of the mode changeover valve, and makes the response speed of the cylinder 4 faster. When the switch 28 is operated to become 0N, the valve 24 is changed over to the position of an oil passage with a throttle portion. When the wheel loader conducts advance/retreat, pressure oil from the pump 5 acts upon the pump tilting cylinder through the valve 7 and the position of the oil passage with the throttle portion of the valve 24, and delays its response speed.
