Title: Tennis racket
Inventor: HANASHIMA SATORU
IPC: A63B51/08
Filed: 1994-07-26
Abstract: PURPOSE:To improve the change force and stability of a ball so as to enjoy various shots such as a spin shot, a slice shot and so on by stretching a gut obliquely with a tennis racket standing upright so as to form diamond-shaped meshes. CONSTITUTION:With a tennis racket having a handle 2 and a grip part 3 standing upright, a gut 1 is obliquely stretched on the frame so as to form diamond- shaped meshes. That is, the gut 1, which is usually stretched longitudinally and horizontally, is stretched obliquely from side to side. Spacing of the gut is uniformly held. At the time of using the racket, it is used similarly to the ordinary racket to play tennis. As the racket is excellent in the change force and stability of a ball, various shots such as a spin shot, a slice shot and so on can be enjoyed. Furthermore, as the range of a sweet spot is wide, even a beginner can play tennis with a light heart, and an advanced player can also enjoy a very difficult shot.
Patent JP-S6448101-A (JP)
Title: Control method for follow-up control system
Inventor: KATO TAKAAKI
IPC: G05B7/02
Filed: 1987-08-19
Abstract: PURPOSE:To improve the quick responsiveness and the control precision by switching the control to the feed forward control and the feedback control alternately at intervals of a prescribed time. CONSTITUTION:Feedback control elements 7 and feed forward control elements 10 are alternately inputted to an operation part 8 which operates a controlled system 8. The shorter this switching time is, the better; but the time required for operation of an operation signal inputted to the operation part 8 is a minimum switching time. While the feedback control is not selected the output of an integral element out of feedback control elements is held. Therefore, a quick response is attained because a large manipulated variable is given in the feed forward control. Meanwhile, the control precision is secured in the feedback control though the response is delayed because the manipulated variable is a relatively small value for the purpose of securing the stability of the control system.

Abstract: PROBLEM TO BE SOLVED: To provide an efficient and economical method in which generation of bulking phenomena is prevented and activated sludge in an aeration tank is constantly activated without deteriorating water quality and without inhibiting growth of useful floc formation bacteria, in a waste water treatment facility of domestic waste water and industrial effluent and industrial waste water. SOLUTION: In the method for activating activated sludge, a medium for activating sludge is brought into contact with a bulking control agent for 26-96 hours in the conditions of permeability agitation in a mixing tank. The obtained sludge-activating material is flowed into a place in which retention time is taken in an aeration tank, for example, into the raw water inflow side of the aeration tank. Further, one kind or at least two kinds of returned sludge, sewage raw water, water in the aeration tank and aerated treated water are used as a medium for activating sludge.

Title: Manufacture of bragg reflection film
Inventor: HAKU SOKYO
IPC: H01S5/183
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a method by which a film having a desired thickness can be grown in real time by using a laser beam having the same wavelength as a Bragg reflection film has. SOLUTION: After a plurality of buffer layers are formed on a semiconductor substrate, first and second epitaxial layers are grown on the buffer layers. The growth of the first and second epitaxial layers is continuously measured by using a laser beam having the same wavelength as the reflection wavelength of a Bragg reflection film and the period until the layers grow to the thicknesses of 1/4 wavelength is decided. Since the thickness of the Bragg reflection film grown thereafter is controlled based on the decided growing period, the epitaxial layers can be grown uniformly.

Title: Semiconductor device and its manufacture
Inventor: WADA JUNICHI
IPC: H01L21/768
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of EM(electronic migration) resistance and the increase off wiring resistance in a dual damascene wiring when Ti films are used for the base of an Al film for preventing flocculation. SOLUTION: Ti films 18 for preventing flocculation are formed on the side faces of a connection hole 16 and wiring grooves 17 (17a-17c), prior to the formation of an Al film 19 with a two steps Al reflow. It is not formed on the base of the connection hole 16 or the wiring grooves 17. Thus, Al3 Ti films 20 which operate as EM barrier layers and become the causes of EM resistance deterioration are not formed on the base of the connection hole 16, and the Al3 Ti films 20 which reduce the volumes of second Al wirings 19a-19c and become the cause of the increase of wiring resistance are not formed on the bases of the wiring grooves 17 in the film-forming process of the Al film 19.

Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of power transistors or others in advance by detecting the rotating number of a brushless motor and indicating abnormality to stop the brushless motor when the detected rotating number is kept below a specified value for a preset time. SOLUTION: The actual rotating number of a motor 12 through a motor rotating number detecting circuit 14C, detected by a rotating position detecting sensor 18 is input to a control part 14A. A motor rotating number target map 14B is searched from a speed by a speed sensor 16 at this time and from a steering angle and a steering angle speed by a steering angle sensor 17 to find its target. A signal controller 14 judges the detected rotating number of the motor to be abnormal or not with an abnormality judging circuit provided in the control part 14A. If it judges it to be abnormal, abnormality is indicated by an indicator 22 and a power control 15 is controlled to turn off transistors Q1, Q2, Q3, Q4, Q5, Q6 to stop the motor 12.

Title: Control system of magnetic disk device
Inventor: KOTEGAWA TOYOYUKI
IPC: G11B20/18
Filed: 1982-11-22
Abstract: PURPOSE:To decrease the processing time of a defective record by performing a substitute record allotting control so that the substitute record for the defective record of a mobile head region is allotted on the substitute track within a fixed head region. CONSTITUTION:A table shows the correspondence of addresses between the defective record and the substitute record, and the cylinder address and the head address are recorded to an ROM20 together with other control information. A controller 30 sends a seek instruction to be given to a cylinder address 901 to a magnetic disk device 10 by the control information given from the ROM20 in case the record identification information shows the defective record. The device 10 completes the seeking action after about 30 microseconds without having the seeking action of a mobile head which requires several to several tens milliseconds that are allotted to the mobile head region since the address 901 is allotted to a fixed head. Then the controller 30 sends a record research instruction to the device 10 from the ROM20 and executes an R/W operation after detecting the desired record.

Title: Control device for superconducting apparatus
Inventor: HAYASHI MASATAKA
IPC: H01L39/04
Filed: 1987-08-20
Abstract: PURPOSE:To prevent a superconducting apparatus from being quenched by a method wherein a superconductor whose critical temperature or critical magnetic field is different from that of a superconductor for the superconducting apparatus is built in and controls an electric current to be conducted or a cooling operation. CONSTITUTION:Superconductors whose critical temperature or critical magnetic field is different from that of a superconductor for a superconducting coil(b) are built in as sensors C1-C6; an electric current to be impressed on the superconducting coil (b) or a cooling operation of a cooling device (a) is controlled by signals from these sensors C1-C6. That is, if temperature values of less than the critical temperature are taken at two points T1, T2, an electric current I1 flowing to the superconductor at T1 differs from an electric current I2 flowing to the superconductor at T2. In general, if T1>T2, I1<I2; accordingly, even when the temperature value of the superconductor is increased from T2 to T1, a quenching phenomenon is not caused if the flowing electric current I2 is lowered to I1.
