Title: Setting method for adaptive engine output mode in shoe slip control
Inventor: YAMAMOTO SHIGERU
IPC: E02F3/85
Filed: 1988-04-05
Abstract: PURPOSE:To enable an optimum shoe slip control by shifting a transmission so as to cope with each step of the work of a crawling vehicle and switching to the engine output capable of continuing work running as well. CONSTITUTION:The engine output mode corresponding to the work during running is taken to be controlled by dividing into a dozing A, the lipping B by a 1st speed, the lipping C by 2nd speed and 3rd speed and a reverse D. A transmission is shifted by dividing into each step and the adaptive engine output mode necessary for continuing the work running is set with maintaining the necessary shoe lip rate as well. The most effective shoe slip control can thus be executed corresponding to the work state, speed step or the hardness of a soil/rock bed, etc.

Abstract: PURPOSE: To permit the better separation of fluids such as air and water, jointly  incoming through an intake pipe by providing a funnellike portion inside the body  and also providing a conical splitter inside its chamber.  
     CONSTITUTION: When injecting water into the inflow hole 4 drilled in the tangential direction of the body 2, a free swirl is formed inside the vortex flow chamber 1, a forced swirl is formed at its central part, and the water is flowed out of the discharge hole 6, whereupon a negative pressure region is formed near the central portion, caused by a centrifugal force effect originated from the forced swirl flow, inside the vortex flow chamber 1. Then, air is sucked into the vortex flow chamber 1 through a check valve (not illustrated) and the intake pipe 11 and then the air with said water is flowed in a spiral form into the inside chamber 8 through the discharge hole 6. The air, however, is bubbled by the conical splitter 9, moved jointly with the swirl flow of the water effectively toward the vortex flow chamber 1 along the funnellike circumferential wall of the inside chamber 8, and then discharged out of the inflow hole 4.

Title: Optical head
Inventor: DOI AKIHIKO
IPC: G02B7/00
Filed: 1985-04-23
Abstract: PURPOSE:To eliminate the possibility of a condensing device from collision with an information storage medium even when focusing deviation occurs by providing a luminous flux state changing device that changes the state of divergence or convergence of luminous flux that passed a collimating device. CONSTITUTION:When the state of flux L of laser beam passed through a collimating lens 23 is set to parallel luminous flux, the flux L of laser beam passed the collimating lens 23 converges at a position close to an objective 25 in a case where the collimating lens 23 is placed apart from a semiconductor laser 21. When the collimating lens 23 is placed apart from the semiconductor laser 21 and an information storage medium 22 gets off from the objective 25, focused state can be maintained by bringing the collimating lens 23 close to the semiconductor laser 21. Accordingly, it is not necessary to shift a condensing device to the direction of its optic axis and there is no possibility of colliding of the condensing device against the information storage medium even when focus deviation occurs.

Title: Learning control device of idling rotation number of internal-combustion engine
Inventor: TOMIZAWA NAOMI
IPC: F02D41/16
Filed: 1983-05-18
Abstract: PURPOSE:To enable to control an idling rotation number promptly by learning a feed-back correction volume and setting a learning correction volume for correcting a basic conrol value and taking a correlation with a target rotation number. CONSTITUTION:An idling control valve is provided in an auxiliary air passage bypassing a throttle valve of an intenal-combustion engine. A correcting means of a learning correction volume takes a weighing average of a feed-back correction volume and a learning correction volume to renew the data of the same rotating number in RAM for using it as its new learning correction volume. A control value computing means computes a control value of a duty ratio of a pulse signal by adding the feed-back correction volume and the learning correction volume to a basic control value. In this way, a correlation with a target rotating number is taken, so that a prompt control of an idling rotation number is possible as well as to improve the stability of the idling rotation.

Title: Error correcting method of information word
Inventor: DOI TOSHITADA
IPC: H03M13/00
Filed: 1985-04-22
Abstract: PURPOSE:To correct a burst error effectively by correcting words of the 2nd block with the 2nd error correcting word, constituting the 1st block of the words of the 2nd block, and correcting the 1st block with the 1st error correcting word. CONSTITUTION:Syndromes y1, y3, y5, y7, and y9 are generated by the adding circuit 9 of a decoder and syndromes x-7, x-5, x-3, x-1, and x1 are generated by the adding circuit 10. All bits of those syndromes are all ''0'' unless an error occurs. A correcting logical circuit 11 makes errors. For example, if x1not equal to 0 and y1=0, either of e2 and ep1 is present and when x1=y5, an error word e2 relating to A2 is present, thereby showing that received data is A2+e2. Therefore, x1=e2, so an adding circuit a2 calculates A2+e2+x1 to obtain a correct word A2. Then, delay crcuits D15 and D7 are cleared and when an advance to the next step is made, x1=y5=0. When x1not equal to y5 and x1=9, an error word ep1 relating P1 is present.

Abstract: PURPOSE:To prevent irregularity based on the deformation of a supporting grid from occurring due to the contraction of a strap and thermal distortion by welding heat in a method to fix a strap intersection part after longitudinal and lateral straps are intersected in grid shape in the supporting grid for nuclear fuel. CONSTITUTION:When the strap intersection part 5h of a grid composition 5c in which the longitudinal and lateral straps 5a, 5b are formed by intersecting orthogonally is welded, all the strap intersection parts 5h can be welded by welding the strap intersection part 5h on the surface side 5A and the strap intersection part 5h on the back side confronting with it simultaneously or so. In other words, since the strap intersection part 5h on the base side 5B can be fixed when the thermal deformation of the longitudinal and lateral straps 5a, 5b occur by welding the strap intersection part 5h on the surface side 5A, the irregularity of the supporting grid due to the thermal deformation can be blocked.

The prescribed wavelength light receives the gain during the propagation in the other waveguide and is partly returned to the one waveguide. The uniform output without depending upon the wavelength is obtd. from the one waveguide.
