Title: Arc length controller
Inventor: SAITO NOBORU
IPC: B23K9/167
Filed: 2000-03-16
Abstract: PROBLEM TO BE SOLVED: To provide an arc length controller detecting the change of the arc length of non-consumable electrode welding and controlling the arc length to make it constant and non-consumable electrode welding equipment. SOLUTION: The contact or the noncontact time of a welding wire to a molten pool, can be detected by electric changes such as the voltage, the current or the resistance of an electric circuit formed between the welding wire and a base material. By comparing the contact time with a preset standard contact time, the change of the arc length of a non-consumable electrode can be detected. By taking this contact time as a control factor and by moving a welding torch in the vertical direction to the base material, controlling is performed so as to obtain a proper arc length.

Title: Engagement control device for electromagnetic clutch
Inventor: YAMAMOTO MASAHIRO
IPC: F16D48/06
Filed: 2000-03-22
Abstract: PROBLEM TO BE SOLVED: To relax the drawing shock to be generated just before completion of the engagement of an electromagnetic clutch with the appropriate engagement control corresponding to the accelerating condition. SOLUTION: The current (i) to be supplied to an electromagnetic clutch is raised like a figure under the predetermined condition after a moment t1 when the electromagnetic clutch operating command is switched from release to engagement, and the electromagnetic clutch engaging torque Tc is thereby gradually increased. At a moment t2 when the engine speed Ne comes close to the primary pulley rotating speed Np with a progress of the connection of the electromagnetic clutch and a difference of the input and the output rotating speed of the clutch (Ne-Np) becomes less than 250 rpm showing a moment just before the completion of engagement of the clutch, the clutch current (i) is contemporarily lowered so as to contemporarily lower the clutch engaging torque Tc.  With this structure, a torque stage difference ΔTce between the clutch engaging torque Tc and the engine output torque Te at a moment t3 when the clutch engagement is concluded becomes small, and the drawing shock of the torque due to the torque stage difference can be reduced.

Title: Program guide device, and device and method for inference
Inventor: MASUGUCHI HIDEAKI
IPC: H04N5/00
Filed: 2000-03-27
Abstract: PROBLEM TO BE SOLVED: To display program candidates matching the preference of a viewer. SOLUTION: Words and phrases constituting a program name are evaluated and according to the result, a program candidate is extracted. Here, the evaluation is carried out by referring to past program names which are already selected. The evaluation of words in an extracted information table shown in Fig. 9 is determined according to the total points of 'evaluation points of words themselves' and 'evaluation points of relevant words'. The 'evaluation points of words themselves' man that appearance frequencies of the words. The 'relevant words' stand for words identical to the considered words included in the program name and the 'evaluation points of relevant words' are the total of relative appearance probability × the appearance frequencies of the relevant words themselves.  The relative appearance probability is the appearance frequency of simultaneous appearance frequency/corresponding word. The evaluation of the words and phrases which is thus obtained is applied to the name of a program expected to be broadcast and a program with high evaluation is inferred as a program that the viewer prefers more and preferentially displayed as a program candidate.
