Title: Serially layered column for automatic vending machine
Inventor: YOSHII KIYOAKI
IPC: G07F11/48
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To make a merchandise ejecting device compact, to reduce manufacturing costs, and to attain the sure ejection of merchandise by forming a merchandise passage like a wave, and supporting one part of the self-weight of merchandise by the side wall of the merchandise passage. SOLUTION: Merchandise passages 1a-1f are formed like a wave, and one part of the self-weight of merchandise is supported by the side walls of the merchandise passages 1a-1f so that a charge added from the merchandise to a merchandise ejecting device 4 can be made smaller than a conventional serially layered column equipped with a straight merchandise passage. Also, a column main body 1 of this serially layered column is made of resin so that the side walls of the merchandise passages 1a-1f can be made relatively thick and difficult to be deformed. Therefore, even when an impact charge is added from the merchandise moving downward in the merchandise passages 1a-1f to the side walls of the merchandise passages 1a-1f, the side walls of the merchandise passages 1a-1f can not be deformed.  The column main body 1 is formed as a resin synthetic molded product so that the assembling work of the column main body 1 can be simplified, and the manufacturing costs of the serially layered column can be reduced.

Title: Underwater pump
Inventor: NAKADA MAKOTO
IPC: F04D15/00
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent an underwater pump from being affected by external factors such as the load state and ambient temperature by setting the cutoff timing of an auxiliary winding circuit based on the numerical value directly detected with the actual revolving speed of a motor via a hole IC. SOLUTION: An electronic power device 6 has a role for cutting off an auxiliary winding circuit when a motor reaches the prescribed revolving speed. When a main winding 2 and an auxiliary winding 3 are excited, a capacitor start motor is rotated to start the operation of an underwater pump. When a hole IC detects that the actual revolving speed of the motor reaches the numerical value optionally set by a control device 5 in advance, the excitation to the auxiliary winding 3 is cut off by the electronic power device 6, and the underwater pump is switched to the normal operation conducted by the excitation to the main winding 2. The cutoff timing is slightly delayed by the control device 5, thus acceleration torque is generated, and the normal operation with no chattering can be realized.

Title: Phase distortion compensating circuit of light emitting diode for optical communication
Inventor: HAYASHI MUNEO
IPC: H04B10/00
Filed: 1984-03-17
Abstract: PURPOSE:To compensate easily a phase distortion by providing a negative feedback loop to a circuit driving a light emitting diode and connecting a varactor diode in parallel with the negative feedback loop to make the negative feedback cmount depending on a drive current. CONSTITUTION:A drive current Id of a light emitting diode LED4 flows as it is to an emitter resistor 5 (resistance value R5). A VE of a transistor (TR)1 is Id R5, which is depending on the drive current Id. When the current Id is small, the VE is low, a reverse bias of a varactor diode VCD12 is shallowered and a capacitor Cd of the VCD12 is larger. Since the VCD12 is connected in parallel with a resistor 5 via a resistor 8, the feedback amount of a high frequency region of a negative feedback loop is decreased by the increase in the capacitance and the high frequency characteristic of the optical output of an LED4 is increased. When the current Id is large, the high frequency component of the output of the LED4 is decreased conversely as above. The phase distortion is corrected independently of the other characteristic adjustment by adjusting the resistor 8 and a variable voltage source 13. Thus, the phase distortion is adjusted easily.

Title: Shot blasting method for hull's shell plating
Inventor: BABA EIICHI
IPC: B63B1/34
Filed: 1981-04-06
Abstract: PURPOSE:To save expenses required for hull's shot blasting and contrive reduction of resistance to the hull by means of applying shot blasting only on the shell plating at lower level than the load water line for the range as far as the hull's shell plating asperity covers almost one fourth of the ship's length from  the bow end which greatly contributes to the hull's resistance. CONSTITUTION:Shot blasting is applied only on the shell plating at lower level than the load water line for the range 2 as far as it is approximately one fourth of the ship's length from the bow end which is part of the hull recognized as that the hull's shell plating asperity greatly contributes to the increased in the hull's resistance, and the shot blasting is not applied for other hull's parts. Thus, necessary expenses for applying the shot blasting can be widely reduced to approximately one fourth, and approximately 43% of the increase in the hull's resistance can be lessened. Further, as to the range not alone at the bow part but also as far as it is approximately one fourth from the stern, if the shot  blasting is applied, the increase in the hull's resistance can be reduced as much as approximately 70%.

Title: Electron source for picture display
Inventor: WATANABE MASANORI
IPC: H01J29/46
Filed: 1978-04-28
Abstract: PURPOSE: To obtain a uniform electron beam from the entire cathode by eliminating a potential difference across a linear hot cathode, arranged at the flank opening part of a back electrode, while no electron is derived from the cathode.  
     CONSTITUTION: Inside of cylinder back electron 2 in a channel or U shape, linear cathode 1 is arranged and on the opening side of electrode 2, leader electrode 3 with several through holes 4 and accelerating electrode 5 are both arranged. Here, electrode 2 is applied with a negative voltage, and electrode 3 with a positive voltage.  Because of the application of the negative voltage to electrode 2, no electron is emitted even in case of heating cathode 1 by power supply V1, but when a negative  pulse voltage is applied to cathode 1 by pulse- voltage generator 7, cathode 1 becomes negative to cause electron emission. At this time, diode 6 is connected to one  terminal of cathode 1 with its direction opposite to the pulse voltage and, in consequence, the potential difference across cathode 1 becomes zero, so that the axial  potential gradient will be zero. A uniform electron beam can therefore be obtained.

Abstract: PURPOSE:To reduce production cost and to improve quality by providing the titled magnetic disc with a substrate of which surface is polished like a mirror surface and forming an ion-injection magnetic layer including iron, cobalt, nickel, or at least one of rare earth elements on a part close to the surface of the inside of the substrate. CONSTITUTION:Iron, cobalt, nickel, or at least one of rare earth elements is ion-injected on the surface of the substrate such as a silicon monocrystal substrate, glass substrate or sapphire substrate of which surface is flatly and smoothly polished like a mirror surface by a known ion-injection device. For instance, 5X10<17>ions/cm<3> (dose) of cobalt and 1X10<17>ions/cm<3> (dose) of platinum are injected at 500KV acceleration voltage. Consequently, the magnetic injection layer consisting of cobalt/platinum alloy and having 300oe or more coercive force is formed with about 1,000Angstrom  interval from the surface. A layer consisting of a material of the substrate itself exists on the surface of the magnetic injection layer originally as a protective film. Thus, the production cost is reduced and the protective film which is essential to a thin film disc is automatically formed.
