Title: Positioning device for discoid object
Inventor: KOBAYASHI JIROU
IPC: H01L21/027
Filed: 1981-07-25
Abstract: PURPOSE:To perform positioning quickly and highly accurately by detecting a recessed part cut in a discoid wafer while rotating the wafer. CONSTITUTION:When a wafer 1 is rotated, the detecting voltage of a photoelectric element 33 is changed on account of a notched part provided in the wafer 1. The position of the notched part is found by using the periodical  change of detecting voltage synchronizing with the rotation of the wafer 1. A microcomputer 100 controls the quantity of rotation by the relation between the speed of rotation and the detecting voltage from the photoelectric element 33 so that the notched part is located on the prescribed position and then stops the wafer 1. Since the wafer 1 can be rotated comparatively quickly until the  notched part is detected at the starting of rotation, the wafer 1 can be quickly  fixed.

Title: Coding method of two- dimensional information
Inventor: JIEEMUSU DEI JIYONSUTON
IPC: H04N19/94
Filed: 1990-05-07
Abstract: PURPOSE: To realize an efficient bit speed reduction mechanism by combining multi-dimension no-noise compression and deletion of encoding of blocks meeting a perceptual reference. CONSTITUTION: An encoder 12 has an analysis filter bank 22, and an image signal is applied there. The signal is preliminarily sampled for a digital filter, and further, a signal average value is substituted by a processor 21 and is quantized to 8 bits and is inputted to a perceptual model 28 and a multiplexer 30. A coder 24 responds to a minimum band (0, 0) picture in both directions. A quantization encoder device 25 makes a quantization process and an encoding process respond to perceptual analysis occurring in the perceptual model 28 in response to a human visible system adaptive signal of a lead 26. Thus, the quantity of the quantization noise is increased if perception is impossible, and unprecedented data compression of a transmission picture or a stored picture is realized without perceptible degradation at the time of reconstitution.

Title: Method for starting synchronous motor-generator
Inventor: OHARAGI HARUO
IPC: H02P1/52
Filed: 1993-05-18
Abstract: PURPOSE:To prevent damage to a wedge by changing operation from a means for driving the rotary shaft of a generator to a means for supplying power to the armature winding of the generator when the rotational speed of the generator exceeds its rated value by a specified amount. CONSTITUTION:To start a turbine generator 1 from a rotational speed of zero, a starter 5 is driven with a switch S2 open. When the turbine generator 1 has been started, its rotational speed is detected using a speed detector 9. When detected speed reaches 4-5% of the rated rotational speed of the turbine generator 1, a power inverter 34 is started according to a rotational speed signal from a thyristor start judging unit 60. Further, the switch S2 is closed to pass an alternating current through the armature winding of the turbine generator 1, and the operation of the starter 5 is switched to that of a thyristor starter 7. This prevents damage to the wedge of the rotor due to arcing, and shortens the starting time.

IPC: H01M4/74
Filed: 1994-05-30
Abstract: PURPOSE:To prevent the occurrence of a short service time due to the separation and fall of an active material by using an expanded grid body with round measures distributed in both horizontal and longitudinal directions, and irregularities formed on the internal side of each measure, as a positive plate for a lead- acid battery. CONSTITUTION:An expanded grid body 2 formed out of lead or lead alloy having round measures 1 approximately evenly distributed in horizontal and longitudinal directions, is used as the positive plate of a lead-acid battery. This grid body 2 is prepared by inserting a conical jig into the diamond shape measures of a conventional grid body, and deforming the measures into round shape. In this case, the internal side of each measure can be made to have irregularities. According to this construction, the growth of the grid body 2 is restrained, thereby providing long service life and preventing the reduction of active material charging space. Thus, no capacity drop occurs. Furthermore, adhesion between the grid body 2 and an active material becomes firm, and the separation and fall of the active material can be prevented, thereby providing a battery having long service life.

Title: Dielectric resonator
Inventor: ISHIKAWA YOHEI
IPC: H01P7/10
Filed: 1987-05-13
Abstract: PURPOSE:To decrease the Joule loss and to improve the Q by removing the dielectric in the vicinity of the center axis of the distribution of electromagnetic field so as to prevent currents from being concentrated onto the center axis of the electromagnetic field distribution. CONSTITUTION:A silver electrode is coated onto the entire surface of a ceramic base 7 and dielectric resonators 52, 57 having a shape of four-division of a doughnut-shaped dielectric resonator in contact with the silver electrode are baked to the silver electrode. The electromagnetic field distribution taking the center axis of the doughnut shape as its center axis is caused in the dielectric of the dielectric resonators 52, 57 because an electric barrier exists at the position where the electrode exists. The distribution of a displacement current flowing into the dielectric is parted from the center axis by removing the dielectric in the vicinity of the center axis. Thus, the current flowing to the electric barrier is dispersed without being concentrated in the vicinity of the center axis, the Joule loss is reduced as a whole and the dielectric resonator with high Q is obtained.

Abstract: PURPOSE:To firmly stick a metallic thin film tape entirely onto the internally curved surface of the bulb of a ring-like fluorescent lamp, without possibility of exfoliation by using as an adjacent conductor a tape which is provided with the metallic thin film on a resin-made base, by sticking said tape onto the external surface of said fluorescent lamp while heating said tape up to such temperature at which this resin-made base at least generates thermal deformation. CONSTITUTION:As adhesive layer 5 is set up entirely on the one side surface of a base 3 made of polyester, and an Al thin film layer 4 narrower than that of the base 3 is set up on the surface of the adhesive layer 5. Consequently, the Al thin film layer 4 is firmly stuck onto the surface of the fluorescent lamp 1 by means of the adhesive layer 5 whose width is wider than that of the Al thin film layer 4. When stuck, a tape 2 is heated up to such temperature at which the base is thermally deformed, with the result that the tape 2 is completely stuck onto said surface without generating gap and exfoliation between the tape 2 and the fluorescent lamp 1.
