Title: Cz single crystal having holding part for preventing falling down
Inventor: KIDA MICHIO
IPC: C30B15/30
Filed: 1987-04-09
Abstract: PURPOSE:To obtain a CZ single crystal having a holding part to prevent the falling down of the single crystal and to enable the growth of a longer and heavier single crystal than a single crystal produced by conventional method, by forming a shoulder part at the top part of a straight body of a single crystal pulled up by Czochralski process and making the diameter of the shoulder part to be larger than that of the straight body part. CONSTITUTION:A seed crystal 15 is dipped in a molten Si 18 in a quartz crucible 11 and a single crystal is pulled up together with formed neck part 2. In the above process, the pull-up speed is sufficiently lowered and the temperature of the molten liquid 18 is decreased. A shoulder 10 having larger diameter than the straight body part 4 of a single crystal S is formed at the top part of the single crystal S by this process. The pull-up speed of the seed crystal 15 is raised to a normal level to pull up and Si single crystal S having a straight-body part 4 of a prescribed diameter. The diameter of the shoulder part is selected to be larger than that of the straight body part 4 by at least 6mm and at most 6mm + (the diameter of the straight body part) X 50%. The falling down of the single crystal S can be prevented by holding the shoulder part 4 with a safety ring 17. In the figure, the numbers 2, 11 and 13 are neck part, crucible and upper shaft, respectively.

Title: Controlling for pwm inverter
Inventor: KOIKE MASAHIRO
IPC: H02M7/48
Filed: 1980-06-30
Abstract: PURPOSE:To maintain the content of higher harmonic components at low value in a PWM inverter output wave by a methd wherein the pulse width ratio is kept constant at each of the multiple rectangular pulses generated during a half wave period. CONSTITUTION:A basic pulse generating circuit 2 receives clock pulses from a clock pulse generating circuit 1 and transmits rectangular pulses (c) whose width is different from the received clock pulses to an integration circuit 3. The integration circuit 3 changes the received rectangular pulses (c) into triangular pulses (d) of different height and transmits them to an amplitude variable circuit 4. The amplitude variable circuit 4 converts the received triangular pulses into ones of the same height and different bases and transmits them to a composite circuit 6. Output of the composite circuit 6 is subjected to sequential switching by timing signal forming circuit 5 timing signals and is received by a comparing circuit 7 in which a comparison is made to a reference voltage EO. During the period of a level higher than EO, gate signals are supplied to a singal forming circit 9, causing switching signals X, -X, and Y to be outputted. This method results in a decrease of higher harmonics in an inverter output.

IPC: A61F2/00
Filed: 1994-04-26
Abstract: PURPOSE: To provide a fixation element in specialized form that can decrease looseness of the fixation element by substantially increasing working rotary stability to be higher than that of a conventional fixation member while keeping the corresponding ability against the load in axial direction. CONSTITUTION: Fixation member 1 implanted into bone or other tissues is made of tissue affinity material such as titanium or the like in the form of a screw of externally threaded type. Fixation member 1 can be used to support, for example, a prosthetic or artificial joint part. In order to increase rotary stability thus preventing the looseness of fixation member 1, thread 4 of a screw is provided with, for example, a notch 7 by forming a spiral (or linear) groove 5 in the screw face around fixation member 1. Therefore, when fixation member 1 is implanted into, for example, a bone tissue, the tissue is led into notch 17, thus forming a key to stop the returning of the screw and rotation of fixation member 1.

Title: Manufacture of resin sealed electronic component
Inventor: NISHIYAMA KATSUMI
IPC: H01G13/00
Filed: 1989-04-07
Abstract: PURPOSE:To reduce manufacture time and improve adhesion between precoat agent and sealing resin by a method wherein the sealing resin is sealed on semi-solidified precoat agent. CONSTITUTION:Since precoat agent 3 applied on the surface of a device 1 flows, the precoat agent 3 is semi-solidified by ultraviolet-ray radiation or the like to a degree that it has no fluidity. The semi-solidified precoat agent 3 has sufficient adhesion ability compared with that of completely solidified agent so that if the surroundings of the device 1 applied with the precoat agent 3 are sealed by sealing resin 4, the precoat agent 3 and the sealing resin are tightly adhered to each other with adhesive power of both of them. Heat at the time of sealing the resin is transmitted to the precoat agent 3 thereby completely solidifying the precoat agent 3. Thus special heating treatment of the precoat agent 3 is not necessary thereby remarkably reducing manufacture time.
