Title: Work vehicle
Inventor: KYOKANE YASUAKI
IPC: B60W30/00
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To provide a work vehicle having a capability of performing prompt and smooth speed control against disturbances during vehicle speed control. SOLUTION: In this vehicle, vehicle speed V0 is read (S11) and acceleration ΔV is calculated based the vehicle speed V0 and the preceding speed V0-1 (S12). A predicted value of vehicle speed VX after a predetermined time α is calculated based on the calculated acceleration ΔV (S13). Then, the predicted value of vehicle speed VX is compared with reference control speed VR set in advance to control the predicted value of vehicle speed VX to a value less than prescribed maximum speed Vmax (S14). In this case, when it is judged that the predicted value of vehicle speed VX is likely to exceed the reference control speed VR, a target throttle opening degree is calculated using a control map based on the acceleration ΔV and a current throttle opening degree TA0 (S15).  Then, the throttle valve opening degree is controlled to be the calculated target regardless of a stroke amount of an accelerator pedal so as to perform smooth speed control without delay.

IPC: B60R21/00
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent a sensor from deteriorating in detection precision, owing to a worsened detection visual field resulting from the sticking of rain, mud, etc., by putting a sensor for backward information detection in the case of a high-mount stop lamp installed in a cabin. SOLUTION: The sensor 8 which is a stereoscopic camera for detecting rearward information on this vehicle is stored in the case 5 of the high-mount stop lamp 4 installed in the cabin. Consequently, the sensor 8 is placed at a place where the influence of an air current accompanying a travel of the vehicle is little and a relatively excellent rearward visual field is obtained, so that the detection visual field of the sensor 8 deteriorates less than in the conventional technology, Further, the sensor is stored in the movable area of a rear wiper 3 and then any special mechanism is needed for the sensor 8 by moving the rear wiper. Further, the sensor 8 is arranged below a rear roof 1 and at an inner position in the case 5, and then the direct sunshine hardly impinges. so that the adverse effects of the sunshine on the sensor 8 can be prevented.

Abstract: PURPOSE:To obtain a clear picture and also to simplify a circuit constitution, by changing the quantity of light of a light spot for recording each picture element, by recording information of its adjacent picture element, so that it can be recorded by the same density at all times. CONSTITUTION:In order to raise the density of picture elements of both ends, to which a picture element being independent in the lateral direction, and its adjacent picture element are not recorded, an irradiation ray is not made same at all times, but is varied. That is to say, the independent picture element, to which the picture elements of both the ends are not recorded is made L3 by increasing the quantity of a light beam. In this way, when the quantity of light is increased, the density of an independent point is increased, recording is continued, and it can be made almost same density as the picture element. In this regard, as for picture elements 12-4, 12-5, 12-9, 12-11, etc. to which one end is not recorded, too, sag of the shoulder can be corrected by increasing the quantity of light. Also, this system is capable of modulating the quantity of a light beam such as (d) by means of a simple circuit constitution.

Filed: 1979-10-22
Abstract: PURPOSE:To prevent the clogging of a nozzle due to the dust in ink by arranging a filter having a corrosion-proof property against the ink between a vibrating plate and a base plate. CONSTITUTION:The base plate 1 made of a synthetic resin material having the corrosion-proof property against the ink is formed monolithically with the nozzle 2, a pressure chamber 3, a feeding channel 4, a feeding chamber 5 and a feeding pipe by injection molding. The filter 21 formed of a porous member having the corrosion-proof property against the ink is held between the vibrating plate 7 and the base plate 1 and bonded thereto, while the outer-peripheral part 22 of the filter is sealed up by a sealing material. The ink flows from the feeding channel 6 to the pressure chamber as shown by an arrow. It is desirable that the vacant orifices of the filter are of the size of several mu to several tens of mu, since the coarse meshes of the filter 21 allow the increase in the back flow of the ink, while excessively fine meshes cause the shortage of ink feeding.

IPC: F04B37/16
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent flying up of dust in the neighbourhood of water vapor pressure as well as at the time of starting exhausting. SOLUTION: Previously set target number of rotation of a vacuum pump 2, rate of change of the number of rotation and stage change-over time are stored for first and second stages respectively in an exhaust condition storage part 6 so that turbulence is not generated in a vacuum chamber 1 during an initial exhaust period and so that the boiling of moisture does not take place during a water vapor pressure period. A rotation control part 7 increases the number of rotation of the vacuum pump 2 at the stored rate of change of the number of rotation and when it reaches the target number of rotation, it holds the target number of rotation. Thereafter, when elapsed time becomes stage change-over time, change-over to a following stage or finish of control motion of the number of rotation is carried out. In this way, flying up of dust is prevented by preventing generation of turbulence in the vacuum chamber 1 during the initial exhaust period and boiling during the water vapor pressure period.

Title: Brake force holding controller
Inventor: KOSHIZAWA TOSHIBUMI
IPC: B60W10/18
Filed: 1986-06-12
Abstract: PURPOSE:To achieve a smooth starting by providing means for detecting the brake force and determining a time interval from the start of clutching operation to the hold release operation according to the brake force at the start of holding operation. CONSTITUTION:When a braking solenoid check valve 3 is not functioning, the pressure level detected by means of a control pressure sensor 2a is stored by means of a controller 6. Then a current level read out through the sensor 2a is compared with a previously stored pressure level, and if the pressure level at current time point is higher, the current read-out level is stored again so as to store the maximum level at all times. A time interval from the start of clutching operation to the hold releasing operation, i.e. the time interval until the solenoid check valve 3 is opened, is determined according to the stored pressure level. Consequently, the brake force can be released with a proper timing corresponding to the traveling condition of vehicle thus achieving a smooth hill start easily.

Abstract: PURPOSE:To flatten the surface of an interlayer insulating film by a method wherein a resist pattern is provided surrounding the protruded region of the interlayer insulating film on a wide-widthed wiring in the height same as that of the protruded region, a resist is coated thereon, and the resist and the insulating film are etched away at the same speed of etching. CONSTITUTION:Al wirings 3-5 are provided on an Si substrate 1, and an SiO2 film 6 is formed by performing a bias sputtering method. A resist pattern 7 is formed surrounding the protruded part 6 left on the wide-widthed wiring 3 in the same height as the protruded part 6. Then, a resist 8 is coated on the whole surface. When anisotropic etching is performed under the prescribed pressure using the mixed gas of CHF3+C2F6+O2, the resists 7 and 8 and the SiO2 film 6 are etched away at the same speed of etching, and a flat surface is obtained. Then, windows 9 and 9' are provided, and an Al wiring 10 is attached. As the thickness of an interlayer insulating film becomes same on the wiring irrespective of the width of the Al wiring, the non-uniformity in the condition of formation of windows caused by the irregularity in film thickness can be removed, and the number of unsatisfactory connections can also be reduced.
