Title: Cemented carbide
Inventor: PERU GUSUTAFUSON
IPC: C22C1/05
Filed: 1993-12-20
Abstract: The present invention relates to a new process for binder phase enrichment. The process combines binder phase enrichment by dissolution of cubic phase with the requirements that cause formation of stratified layers, resulting in a unique structure. The new structure is characterised by, in comparison with the ones previously known, deeper stratified layers and less maximum binder phase enrichment. The possibility of combining dissolution of the cubic phase with formation of stratified layers offers new possibilities to optimize the properties of tungsten carbide based cemented carbides for cutting tools. The new process offers possibilities to combine the two types of gradients. The dissolution of cubic phase moves the zone with maximum amount of stratified binder phase from the surface to a zone close to and below the dissolution front. By controlling the depth of dissolution, the interstitial balance and the cooling rate a cemented carbide with a unique combination of toughness and plastic deformation resistance can be achieved. <IMAGE>

Title: Control device for self-propelling or mobile work vehicle
Inventor: KAMIKAWA KATSUHIRO
IPC: E02F9/20
Filed: 1992-12-24
Abstract: PURPOSE:To avoid effectuating an emergency stop, when only a part of a device is positioned within an obstacle detection area, by providing a self-invasion detecting means for finding whether or not the part of the device is positioned in that area. CONSTITUTION:Whether or not a boom 17 or a bucket 18 self-invades an obstacle detection area Af is examined, for example, on the basis of a boom angle and a bucket angle. When the boom 17 or bucket 18 is in self-invasion state, an object sensor FL is temporarily made to output an object detection signal. In this case, however, the occurrence of the self-invasion state is already known and the outputted signal is, therefore, disregarded. Then, a travel is made to continue without recognizing the signal as an obstacle. On the other hand, when the self-invasion state is not existing and the object sensor FL detects an object, this object is recognized as an obstacle to be avoided, and a travel is stopped as an emergency. According to this construction, an emergency stop can be effectuated only in a proper case.

Title: Liquid clock
Inventor: MITSUMATA YOSHIO
IPC: G04F1/06
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid clock which has the same function as that of a sand glass and more interests as an ornamental clock by providing plural spaces, one or more parts of which are put in the connecting state in a transparent case, and filling the spaces with two kinds of liquids different in specific gravity or the like. SOLUTION: Plural spaces 2, one or more parts of which are put in the connecting state are provided in a transparent case 1, and the spaces are filled with two kinds of liquids 4 (liquid A) and 5 (liquid B). Both liquids A and B will not mix, the liquid A is transparent and has the same refractive index as that of a transparent body of the case 1, but the liquid B is opaque and different in specific gravity. For example, if the specific gravity of the liquid B > that of the liquid A, the liquid B fills the lower (upper) space, and only the liquid B can be seen floated below a transparent block. If it is inverted, the liquid B having a larger specific gravity starts to drop in the lower space through the connecting part, and the liquid A moves to the upper space.  Thus, the liquid B drops from the upper space to the lower space for a fixed time, so that the liquid clock can be used similarly to the sand glass, and as the liquid B moves up and down in a transparent body, it can be enjoyed as an ornamental clock.

Title: Sheet material feeding device
Inventor: TAKAHASHI KOJI
IPC: B65H5/06
Filed: 1989-12-28
Abstract: PURPOSE:To prevent a load from being exerted on a sheet during conveyance by increasing the delivery speed of a delivery roller having a separating piece and delivering sheet materials one by one to a value higher than the feed speed of feed rollers on the downstream side. CONSTITUTION:The sheet materials 9 separated and conveyed one by one by means of a separating piece 4 and a delivery roller 3 are fed in a state to be nipped between feed rollers 1 and 2 on the downstream side in a conveying direction. The delivery feed of the delivery roller 3 is increased to a value higher than the feed speed of a feed roller 1. Thus, a slack in the sheet material 9 between the two rollers 1 and 3 is generated and the sheet material is received in the space of a guide plate 6 to receive the sheet material. A ratio in a peripheral velocity between the two rollers 1 and 3 is approximate 1.1-1.2. When the slack is detected by a slack sensor 7, the delivery roller 3 is stopped, and when the sheet material is fed by the feed roller 1 to remove the slack, the delivery roller is operated again. Thus, a press force on the sheet material 9 by the separating piece 4 is rendered in-effective between the two rollers 1 and 3 and no load on the sheet material 9 is produced.

Title: Control device for vehicle
Inventor: TABATA ATSUSHI
IPC: B60L50/16
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To improve control precision of VSC control to effect electronic control of a power source and a wheel brake prior to operation of a driver. SOLUTION: When it is judged that VSC control is under operation (step SA2), the operation state of an engine and a motor generator, serving as a power source, temporarily holds switch to a different operation mode (step SA6). In this way, control of the output of the power source is effected with high precision and since no change of inertia (strictly inertia moment) occurs, brake control of a wheel brake is facilitated and lowering of control precision of the VSC control due to switching of the power source is prevented from occurring.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of required circuits, to improve the calibration of the resolution and the resolution of edge positions by using a comparator connecting to a counter to provide an output of a pulsizing output signal when a pulse period is equal to a control variable. SOLUTION: A frequency fc of an input signal Vc from an oscillator 310 is selected to be fc =1/T and k=fc /f0 , where f0 is a normal frequency of an output signal V1 . A modulo K function block 314 converts a value Nn stored in a memory 322 into a value N'n , and the module function increase or decreases a value K from the value Nn to the value N'n to obtain a range of 0 to (K--1). Then a connector 312 continuously counts the value K and a comparator 316 compares the count Mn with the current value of the N'n . When they are equal to each other, an edge of the output signal V1 advances an address counter 320 and a succeeding Nn in a memory 322 is extracted after a delay of TK/2 by a delay line 318.
