Title: Operation method for unmanned vehicle
Inventor: MAEDA TOMOAKI
IPC: B61B13/00
Filed: 1988-02-10
Abstract: PURPOSE:To improve the conveyance efficiency of an unmanned vehicle by travelling at a low speed when the special type of the conveyance substance weak to an oscillation and an impact is loaded and travelling at an ordinary speed at the time of the empty cargo travelling and at the time of loading other conveyance substance. CONSTITUTION:When a steering/travelling control device C of an unmanned vehicle 1 receives a speed pattern switching command signal, the pattern is switched from a prescribed speed pattern at the ordinary time to a special speed pattern. The special speed pattern is the pattern having a lower speed S(<S0) and a lower acceleration alpha(<alpha0) than a speed S0 and an acceleration alpha0 in a prescribed speed pattern. The unmanned vehicle 1 is travelled by the travelling pattern of a low acceleration alpha and a low speed S at the time of the present cargo travelling (during loading conveyance) and at the time of the empty cargo travelling, is travelled by the travelling pattern of an acceleration alpha0 and a speed S0. Thus, compared with the case the vehicle is always travelled by the travelling pattern of the low acceleration alpha and the low speed S, the travelling time per travelling cycle of the unmanned vehicle 1 is shortened and the transportation efficiency can be increased.

Abstract: PURPOSE:To measure the external diameter of a core, etc., with high accuracy even when an optical fiber base material and refractive index matching liquid has a difference in refractive index by multiplying the apparent core diameter of the optical fiber base material by a correction coefficient and determining the real core diameter. CONSTITUTION:The optical fiber base material 11 is dipped in the refractive index matching liquid 18 with a refractive index (n), laser luminous flux 15 is scanned at right angles to the center axis of the base material 11, and the time when the luminous flux 15 is cut off by the base material 11 is measured electrically. Then the center position of the base material 11 and the center position of the core are determined according to the obtained data and the observed distance between the center of the base material 11 and the center of the core is found from those data. Then, the external diameter and apparent core diameter are determined according to those data and the apparent core diameter is multiplied by the correction coefficient K=n/n1 (n1: refractive index of the clad of the base material 11) to determine the real core diameter. Thus, simple calculation or correction like this is added to accurately evaluate the shape of the base material with high accuracy.

Title: Fuel injection amount control device for diesel engine
Inventor: KIZAKI KANJI
IPC: F02D41/40
Filed: 1992-02-14
Abstract: PURPOSE:To carry out fuel injection amount control by deciding target injection amount suitable for engine speed at the time to actually carry out fuel injection even in the case when change of the engine speed is large. CONSTITUTION:From a standard position of an engine rotational pulse, a pulse number to a target crank angle corresponding to a target injection amount and an excess angle falling short of one pulse are searched for. In estimating angle time used for time conversion of the excess angle, times TN13, TN6 in a same combustion cycle are searched for, and the difference between both of the times TN13, TN6 is made to be a time difference TN equivalent to rotational speed change. Thereafter, the former angle time T51125 (i-1) is corrected in accordance with this time difference TN. Additionally, in searching for rotational speed for computation for target injection amount computation, standard rotational speed NE1 (i) is corrected in accordance with the time difference TN. Consequently, the target injection amount is decided in accordance with the rotational speed for computation after correction estimating rotational speed change at the current combustion cycle.

Title: Photographic density detector for film
Inventor: HOTSUTA TOMIJI
IPC: G01N21/59
Filed: 1981-02-27
Abstract: PURPOSE: To ensure a sufficiently large output of a light receiving element even for slight level of light received thereby by employing a photosemiconductor having function of accumulating an electric charge for the light receiving element for converting transmitted light through a film into an electrical signal.  
     CONSTITUTION: While a linear light source 20 emits a light, a film 10 to be treated is carried in. The light is intercepted by a dense part thereof 10 and the quantity of incident light by light receiving elements D 1 WD n  is reduced. On the other hand, when a switch S 1  contacts for a given time by a scanning pulse P 1  from a shift register 50, a reverse voltage is applied to the light receiving element D 1  for accumulating an electric charge. Then, when the switch S 1  is cut off, the electric charge is lessened with a light current in the light receiving element D 1 . Then, when the switch S 1  conducts for a given time a gain, a charged current is output through a resistance R. The integration of the output enables the output of a value proportional to the quantity of light received by the light receiving element D 1  when the switch S 1  is cutoff.

Title: Liquid crystal display device
Inventor: YANAGAWA KAZUHIKO
IPC: G02F1/1339
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To make the gap between substrates uniform even when a liquid crystal display panel is made large in size, by controlling the supporting force to a substrate of a first spacer group disposed in the peripheral region of the sealed region of a liquid crystal to be different from the supporting force to the substrate of a second spacer group disposed in the center region excluding the peripheral region. SOLUTION: Spacers 10 are dispersed to keep the gap between substrates 1A and 1B in the sealed region of a liquid crystal, namely in the display region surrounded by a sealing material 24. When the display region is divided into its peripheral region and a center region excluding the peripheral region, the number of spacers in the peripheral region is smaller than the number of spacers in the center region. Namely, the density of the spacers per unit area in the peripheral region is smaller than the density in the center region. This means that the supporting force to the substrate of the spacer group disposed in the center region of the display region is higher than the supporting force to the substrate of the spacer group in the peripheral region.

Title: Packet transfer system to matrix switch
Inventor: TSUBOI MITSURU
Filed: 1988-02-10
Abstract: PURPOSE:To prevent the production of aborted packet with less buffer capacity by transferring the stored packet in a reception buffer when the transfer buffer is idle and stopping the transfer of packet to the transfer buffer when the transfer buffer is busy by the monitoring at a status detection section. CONSTITUTION:A detection output of a status detection section 6ij detecting the idle/busy state of a transfer buffer 20ij is monitored by a status detection section 5ip while a packet is being stored in a reception buffer 40ip. When the idle state is obtained by the monitoring, a transfer control section 7ip transfers the stored packet in the reception buffer 40ip to the transfer buffer 20ij and when the busy state is obtained by the monitoring, the stored packet of the reception buffer 40ip to the transfer buffer 20ij by the transfer control section 7ip is stopped. Since the packet is transferred after the idle/busy state of the transfer buffer is checked in this way, the production of aborted packet with less buffer capacity is prevented.

Abstract: PURPOSE: To eliminate complication and to selectively obtain an unglossy copy and a glossy copy by reversely carrying a recording sheet with a fixed image thereon to a different sheet-feed system, and then subjecting the recording sheet to refixing. CONSTITUTION: When the device detects the rear end of the recording sheet which has passed through a fixing device 17 and has finished the fixing of a toner image on its one side, a heat roller 17A and carrying rollers R1-R3 start to rotate reversely all at once, the pressing of the pressure roller 17B is released, and a guide member 51 turns clockwise. Consequently the recording sheet is reversely carried between the heat roller 17A and pressure roller 17B which are apart from each other, and is carried into an inversion sheet feed passage 15B. In this passage 15B, the heat roller 17A and carrying rollers R1-R3 once stop and then return to normal rotations. A carrying roller R4 also starts to rotate reversely, and the pressure roller 17B, separated from the heat roller 17A, is brought into contact with the heat roller 17A.  Then, the recording sheet is ejected onto a tray at the top of the device after repressed between the heat roller 17A and pressure roller 17B pressed against each other.
