IPC: F16H63/06
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To attain forward/reverse switching, a running gear shift, and accurate transmission stopping by means of simple and light-duty speed changing operation. SOLUTION: This working vehicle operates pressure sensitive sensors 53a, 53b with an arm 54 by operating a gear shift lever 55. A gear shift motor M rotates a sector gear 50, and a forward/reverse switching cam part 64 operates an operating body 57 so as to be oscillated by a cam groove 60, so that a switching valve 36 of the forward/reverse switching device is operated through a push-pull cable 56. The sector gear 50 rotates the gear shift operating part 22 of a continuously variable transmission device.  By forming the third cam groove part 63 which switches the operating body 57 in the cam groove 60 of the forward/reverse switching cam part 64 to a forward position or a reverse position, into a bent groove which is bent in a space P between a central groove part 63a and end side groove part 63b, the central groove part 63a keeps the operating body 57 at a neutral position even if the forward/reverse switching cam part 64 is rotated a little excessively from the neutral position to its forward side or its reverse side.

Filed: 1992-02-28
Abstract: PURPOSE:To quickly extract the contents of changes corresponding to the inputted contents of changes out of the unchanged network constitution information and also the changed network constitution information with the history of changes used as a retrieving key. CONSTITUTION:The network constitution information 2-2 is changed and added based on the contents of changes inputted from en input part 1. At the same time, the contents of changes are also inputted to a change control part 3.

An autocorrelation coefficient K between adjacent picture elements on each line of scanning lines is obtained according to a prescribed equation as a physical quantity representing a characteristic of an image content and stored in an autocorrelation coefficient file 16. Then the physical quantities used for estimating a subjective evaluation value MOS, that is, number N of times of occurrence of a deteriorated page, number L of scanning lines included in each deteriorated page, a lateral length W within a range of occurrence of picture element error in the deteriorated image, a picture element error rate B for each deteriorated image, and an autocorrelation coefficient K in an original image information in the deteriorated image are obtained by a physical quantity calculation section 17. Then a MOS calculation section 17 substitutes the obtained physial quantities to equations I, II to obtain the MOS value, where a0-a4, b0-b4 are constants obtained based on subjective evaluation experiment data and a MOS* is a minimum value of the MOS obtained from each deteriorated image.

IPC: G06F9/45
Filed: 1986-03-03
Abstract: PURPOSE:To extend the object range of resolvable conditional statements by providing an induction condition developing part to resolve prescribed loop conditional statements. CONSTITUTION:An intermediate word loop structure 100 and a characteristic table 200 of the loop generated by a loop analyzing part are inputted to an induction condition detecting part 41 of an induction condition developing part 40, and this detecting part 41 checks loop constituting statements and expressions to detect induction conditional expressions. An induction condition characteristic analyzing part 42 discriminates whether induction conditional expressions are start point, intermediate point and final point conditional expressions, and an induction condition development object determining part 43 selects the induction condition to be developed in accordance with characteristics. The loop structure is so converted in a loop structure converting part 44 that the selected induction condition is resolved. Thus, not only loop start point conditional statements and loop fixed conditional statements but also various conditional statements are resolved, and the object range of resolvable loop conditional statements is extended to improve the execution efficiency of an object program.

Filed: 1995-03-03
Abstract: PURPOSE: To provide a signal processor capable of applying signal processing to an inputted signal at high speed. CONSTITUTION: Both planes of an original are read by using two-output linear image sensors 1, 2, and output are stored in memories 3-6. The memories 3-6 output a signal at speed of four times input speed. In such a case, since the two image sensors are driven by clock pulses whose phases are shifted by 1/2 line, data on a second line is read out immediately after the data on a first line is read out.

Abstract: PURPOSE: To attain satisfactory transmission characteristics on the side where the frequency is higher than a trap frequency without deteriorating signal levels and trap characteristics by specifying the electrode finger crossing width of an interdigital transducer (IDT). CONSTITUTION: The plural electrode fingers 23a of a comb teeth electrode 23 and the plural electrode fingers 24a of the comb teeth electrode 24 have equal lengths. The crossing with B of the electrode fingers 23a and the adjacent electrode fingers 24a is set to be constant in whole IDT 25. Namely, IDT 25 is normal-type IDT where the plural electrode fingers 23a and 24a are arranged so that they have constant crossing width. The crossing width, namely, the width B of an area where the adjacent electrode fingers 23a and 24a are overlapped along a surface wave transmission direction X is selected in such a way that a ripple caused by a lateral mode, which is generated between a resonance point and a non-resonance point of an impedance frequency characteristic, is overlapped with the non-resonance point.  It is desirable that the crossing width B is within the range of 2.8λ to 3.1λ when the wavelength of an excited surface wave is set to be λ.

Title: Semiconductor device
Inventor: INAYOSHI KATSUYUKI
IPC: H01L21/82
Filed: 1979-04-12
Abstract: PURPOSE:To make possible multi-layer Al wiring without lowering the yielding rate by a method wherein a conductive film in the wiring region which has been attached simultaneously with a gate conductive film is utilized for wiring in the lowest layer. CONSTITUTION:After making a field oxidized film 15 and a gate oxidized film 16 on a substrate 14, laminating a conductive polycrystalline-Si, providing a photoresist mask 18 and etching them in the gas plasma of CF4, a gate electrode 13 and a wiring layer 10 are simultaneously formed. The oxidized film 16 is removed by means of fluoric acid with the mask 18 and the gate electrode 13 as a mask for etching. Then a source 19 and a drain 20 are formed by the ion injection method, and they are convered by PSG21. Next an Al electrode and wiring 11 are made after providing a window. Then the second Al wiring is added via an insulating layer. By this method, processes after the formation of the polycrystalline-Si film become those for slicing, so the length of each process is long because the formation of source and drain regions is included in them. However, the number of processes is not increased, thus making it possible to form 3 layer wiring by the same method for the conventional 2 layer Al wiring. Consequently, this method is effective for a comparatively large volume of estimated production.

Title: Ignition controller for liquid fuel combustor
Inventor: MURAKAMI SHIGERU
IPC: F23N5/00
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To obtain the optimum igniting condition by a low-cost igniter by connecting a vaporizing heater and an igniting heater contained in a vaporizer in series via an igniting heater control switch controlled by an igniting heater controller. SOLUTION: The ignition controller connects a vaporizing heater 7a and an igniting heater 17 contained in a vaporizer in series via an igniting heater control switch 16a. The heater 17 is conducted by opening a vaporizing heater control switch 14a and closing an igniting heater control switch 16a. Thus, the voltage decided by the resistance ratio of the heater 7a to the heater 17 is applied to the heater 17. With this constitution, since the lower voltage than that at the time of normal heating is applied to the heater 7a during igniting, post-heating at the time of igniting can be simultaneously conducted, and further since the post-heating is conducted by the voltage lower than that of the commercial power source, its overshoot can be lowered.
