Besides, to the front surface of the speaker 1, the non-scattering armor mechanism 3 is provided and the directivity of it can be prevented being confused. Then, a change-over switch selecting the directivity and a directivity adjustment button are disposed more. The motor mechanism 2 is driven by the directivity adjustment button and the speaker 1 can be directed to the desired direction in a room.

Title: Travel stopper in precutting apparatus
Inventor: AOSHIMA TATSUKI
IPC: B27B27/10
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To provide the travel stopper for a precutting apparatus which positions a timber to be worked and conveyed on a conveying passage by mounting a travel member on a rail laid in parallel with the passage and mounting the stopper at the member. SOLUTION: The central part of a cylinder 17 is so mounted at a cylinder support member 16 which is fixed to a travel member 12 as to make it possible to be rotated. Further, the drive shaft 17a of the cylinder 17 is so coupled to the one end of a rotary member 19 mounted at the upper part of the member 12 as to make it possible to be rotated. A stopper 20 is fixed to the other end of the member 19. Since it has a constitution that the stopper 20 is moved up or down by rotating the member 19 of the member 12 with respect to a conveying passage 4 where a timber 8 to be worked is fed, the timber can be arbitrarily sequentially positioned at a desired position. And, since the stopper 20 is raised to be returned to the standby position at the time of finishing the work of the timber, the stopper 20 is not interfered with other apparatus.

Title: Magnetic head
Inventor: HASEGAWA TOMOJI
IPC: G11B5/60
Filed: 1985-12-29
Abstract: PURPOSE:To simplify work by installing a notched part on some part of a slider, retreating a nonconductive adhesive leaking on a core side surface at the time of bonding a core and eliminating a removal in a nonconductive layer at the time of coating a conductive paste between a core and a gimbal plate. CONSTITUTION:The notch 2a is added on a part where the lower square part 4 of the slider 2 abuts on the gimbal plate 3. When the core 1 and the slider 2 are bonded with the nonconductive adhesive, the adhesive leaking from the bonded surface retreats into the notch 2a, and therefore it never goes around the square part R of the core 1. Thus the removal in the nonconductive layer of the core 1 becomes unnecessary, whereby the work bonding the conductive material to the space between the core and the gimbal plate can be substantially facilitated. Provided that, the square part R can be crushed and removed after the cores 1 and 2 are jointed.

Abstract: PURPOSE:To shorten a file access time for retrieval by using the control unit of an information display output as a page, dividing a file into each page and executing the formation, accumulation and retrieval of the file in each page. CONSTITUTION:For instance, one unit of a page file block stored in an external storage device 5 is displayed as a page picture. Information to be collectively displayed is expressed by the list structure of text data, graphic data, etc., having comparatively high data efficiency (the volume of necessary data is less) as a page and stored as the file block of one unit. One unit can be extracted by one file access, data which can not be included in the file block of one unit are stored in another file and information for accessing the file is stored in the list of the page blocks. Consequently, file access for retrieval can be speeded up and information requiring much data such as images and voice can be efficiently accessed.

Title: Method for hermetically closing hole of workpiece consisting of ductile material
Inventor: WOLF MARCUS
IPC: B21K21/14
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To hermetically close the hole within a thick or solid workpiece by successively displacing material toward at least nearly the axial line of the hole within the inner slope cross-section of the hole at the different points of the aperture of the hole. SOLUTION: The axial line of a ram 13 is laterally offset from the axial line of the hole 11 and the diameter of the ram 13 is larger than the diameter of the hole 11. The offset is so set that the right side boundary edge of the ram 13 is aligned to the right side boundary edge of the hole 11. The ram 13 first comes into contact with the point (a) of the aperture 15 and displaces the material of the workpiece 10 into the section of the hole on the inner side, as a result of which the material deformed by plastic flow forms a build-up part and the hole 11 is closed to some extent. Next, the ram 13 is returned to a start position and is offset to the offset position separate from the first axial line and this time the ram is brought into contact with the point (b). At this time, the material is displaced toward the point (a) and the second build-up part is formed.  The second build-up part displaces the first build-up part or both parts overlap on each other to form a barrier to hermetically close the inside of the hole 11.

Abstract: PURPOSE:To utilize the excitation energy of a discharge excitation part effectively and to make the device compact by making a second slit have a width corresponding to the divergence angle of an optical beam passing a first slit. CONSTITUTION:A divergence angle corresponding to the full width at half maximum of the beam strength of an optical beam which passes a first slit 13a and goes to a second slit 13b via a discharge excitation part 1 is a degree of several milliradians, and the width of the second slit 13b corresponds to this divergence angle and is wider than that of the first slit 13a. Incidentally, the beam strength distribution in the discharge excitation part 1 is a Gaussian distribution symmetrical to a plane containing the optical axis of the discharge excitation part 1 and the center line of each slit width of the first and second slits 13a and 13b. Accordingly, it is necessary to coincide the center line of each slit width and that of the discharge excitation part 1.
