Title: Actuator
Inventor: WATABE NOBUAKI
IPC: G03B9/02
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a small size actuator whose rotor has excellent starting performance. SOLUTION: A base plate 1 and a cover frame 5 are made of synthetic resin and support a permanent magnet rotor 8 with its shaft. The bent parts 9a and 10a of core members 9 and 10 are pole parts facing the circumferential surface of the rotor 8. The other bent parts 9b and 10b of the respective core members 9 and 10 are inserted into the cylindrical parts of bobbins 12 and 14. The bent parts 15a and 15b of a linking yoke 15 are inserted into the cylindrical parts of the bobbins 12 so as to overlap the bent parts 9b and 10b. The rotor 8, a protruding part 8a protruding in the radial direction of the rotor 8 and a driving pin (output pin) 8b provided on the tip of the protruding part 8a are permanent magnets made of same material. However, if coils 11 and 13 are in non-conducting states, the protruding part 8a is at a rotation position where it does almost not overlap the core member 10 so as not to have starting performance degraded by a magnetic force between the protruding part 8a and the core member 10.

Title: Production of zinc oxide whisker
Inventor: YOSHINAKA MINORU
IPC: C30B29/62
Filed: 1988-12-22
Abstract: PURPOSE:To obtain a whisker being narrow in distribution of size and having composite effects of huge tetrapod structure by adding carbon dioxide or steam to oxygen-containing atmosphere in a method baking a zinc powder in the oxygen-containing atmosphere. CONSTITUTION:A zinc powder is baked and oxidized in a O2-containing atmosphere to which CO2 and/or steam is added. In this case, shape and distribution range of size of produced tetrapod like zinc oxide is varied by a blend amount of CO2 and/or steam. Namely, as O2 concentration becomes smaller than a certain value based on concentration of CO2 or steam in the atmosphere, yield of produced tetrapod like zinc oxide is reduced and simultaneously becomes smaller in the shape, but the distribution of the size becomes extremely narrow and the size becomes uniform.

Title: Magneto-optical recording magnetic head
Inventor: ARAI NOBUO
IPC: G11B11/10
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To ensure a stable contact state even if a magneto-optical disk has wobbling of a surface and surface irregularity and to reduce the size, weight and electric power consumption of the magnetic head by packing and arranging a material having a slider function on a magnetic field generating periphery and a sliding part between a magneto-optical recording medium and the magnetic head. SOLUTION: A recording magnetic field may be generated by winding a coil 8 on a center pole 11 formed of an Mn-Zn ferrite material and passing a recording signal current to this coil 8. Polyethylene is (PE) packed as the packing material 10 to the sliding part 12 of the magnetic head inclusive of the front surface part of a center pole 11 and the periphery of the sliding part 12. The density of the PE is 0.93 g/cm<3> and the density when calcium titanate is used as the sliding material is <=2/5 of 2.3 g/cm<3> . The reduction of the weight of the head is thus made possible. The follow-up to the wobbling of the surface and surface irregularity of the disk is made possible by the reduction in weight even in the absence of a servo mechanism to follow up the same.

Title: Printing method for alternately combined images
Inventor: TUTT LEE W
IPC: H04N1/23
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To print alternately combined images for visualizing an independent image not to generate banding through a lenticular or blocking line screen by scanning a light beam through a polygon mirror and recording it on an image forming medium while including a specified polygon and using a lenticular medium. SOLUTION: A beam-shaped lens 20 converges a beam 12 on the reflection plane of a rotating polygon 30. Next, a reflected beam 13 is converged while using a beam-shaped lens 40. Each reflection plane of the polygon 30 records one scanning line 52 on the back of a lenticular recording medium 50. Then, the number of reflection planes on the polygon to be selected by the desired images combined alternately is provided by the equality of f/pb=n. In this equation, (f) is the number of images, (p) is the number of reflection planes on the polygon, (b) is the number of write beams and (n) is an integer. Since the image is always scanned by the reflection plane of the same polygon, bandings are reduced.

Title: Manufacture of hydrogen storage alloy electrode
Inventor: YAMAMURA KOJI
IPC: C01B3/00
Filed: 1994-12-27
Abstract: PURPOSE:To provide a hydrogen storage alloy electrode having a characteristic of a high discharge rate at low temperature by immersing and treating a storage allay in a high temperature alkaline solution containing cobalt or copper ions when the alloy is in the form of powder before electrode formation, or after the alloy is formed into the electrode. CONSTITUTION:A hydrogen storage alloy, when in the form of powder before electrode formation and/or in the form of an electrode, is immersed and treated in a alkaline solution containing cobalt or copper ions, and having a high temperature, for example, 65 deg.C or higher. At this immersing process, the cobalt or copper ions in the alkaline solution are reduced, due to oxidation reduction with a specific element such as Mn and V in a hydrogen storage alloy and deposited as metal on the surface of the alloy. In other words, metallic cobalt itself is electrochemically active and, therefore, acts to substantially increase the electrochemical activity of the alloy metal via the synergetic effect with active metal such as nickel exposed on the alloy surface. Furthermore, copper is deposited on the alloy surface, and reduces contact resistance among alloy particles. Thus, the high rate discharge characteristic of a battery is improved and the discharge capacity thereof increases as well.

Abstract: PURPOSE:To obtain the mousepiece of the flute with which rich and excellent sound quality is obtained by providing a projection tongue part which is so formed that the internal surface of a hole on the front side where a lip is applied is extended drooping into a head tube and a recessed curved surface is formed on the reverse surface on the internal wall of the head tube. CONSTITUTION:The tongue part 11 which is so formed that the internal surface of the hole 3 on the front side where the lip is applied is extended drooping and the recessed curved surface 12 is formed on the reverse surface is provided on the internal wall of the head tube 1 to divide the space in the head tube 1 into two, i.e. an acoustic space A and a fluid space B. Namely, a sound is generated by the up-down vibration of air striking on an edge in the acoustic space, a spiral flow is generated in the fluid space to generate a suctional force for the air by the whirlwind effect, thereby reducing the resistance to breathing. Consequently, the generation of the sound is not disturbed by an irregular air flow and the efficiecy of the transduction of the energy of the breathing into the sound can be increased, so that clear, active, and rich sound quality can be obtained.
