Title: Frame for tennis racket
Inventor: JIRE DEYU GARUDAN
IPC: A63B49/10
Filed: 1987-01-13
Abstract: A racket body formed of composite materials in which the shaft portion of the handle, two branches of a throat portion and a frame portion, which can be completed by a bridging portion, adjoin in end to end relationship and have cores and sheaths composed of different materials. The sheaths are comprised of fiber webs or braids impregnated with synthetic resin, the fibers differing along the length of the racket from at least one portion to another, while the orientations of the fibers with respect to the axes of the respective cores can differ from place to place as well. The end portions of thetwo branches of the throat are axially offset from one another so as to avoid the formation of a rupture zone.

Title: Air supply system
Inventor: HAGIWARA TADASHI
IPC: F24F7/10
Filed: 1989-01-11
Abstract: PURPOSE:To make it possible to remove insects in the open air adhering to an insect screen easily and maintain a proper amount of air constantly by changing over a first damper to a third damper based on their interlocking operation and reversing a ventilation direction opportunely through a vent cap having a net screen for a first suction duct. CONSTITUTION:When a first damper 11 and a second damper 12 are interlocked, both ends of a bypass duct 9 are closed, a second suction duct 16 is closed with a third damper 13, then a blower 2 is operated, the open air is discharged indoors passing through a first suction duct 14. At that time, insects or dust in the open air are adhered on a net screen 7 of a vent cap 8 so that they may be prevented from entering indoors. When the amount of the insects or dust adhered on the net screen are gradually increased, and the increase in ventilation resistance in the vent cap 8 is feared, the dampers 11, 12 and 13 are reversely interlocked so that a bypass ventilation passage may be formed and the suction damper 16 may pass through the back of a ceiling. Then, the air in the back of the ceiling is absorbed from the suction duct 16, and discharged reversely outdoors passing through a main body 1, a discharge duct 5, and a bypass duct 9. Then, the insects caught up in the net screen 7 are blown off outdoors.

Title: Electrostatic induction transistor
Inventor: KOTANI MICHIO
IPC: H01L21/331
Filed: 1978-01-18
Abstract: PURPOSE: To obtain a high-dielectric-strength electrostatic induction transistor of high gm by forming a convex part on a semiconductor substrate, by stacking an epitaxial layer, and by providing a gate and source to a part equivalent to the convex part and the other part after flattening the surface of the epitaxial layer.  
     CONSTITUTION: The surface of N - -type epitaxial layer 4 on N-type drain layer 3 with a convex is flattened and N + -type source 5 and P + -type gate are selectively formed at fixed parts. In this structure, the current path from source 5 to drain 3 is long until the drain right under the source before pinching-off when the depletion layer expands slightly from the gate, so that a current will flow from the source to drain 3 right under the gate dispersively. Namely, since a current right under the gate increases, the variation in current due to the variation in gate bias is large. Therefore, gm becomes larger and the gate-drain dielectric strength improves.

Title: Magnetic recording and reproducing amplifier
Inventor: OKABE HIROFUMI
IPC: G11B5/027
Filed: 1994-01-24
Abstract: PURPOSE:To reduce a hairnoise generated at the time of the switching of a switching transistor changing the value of an input at the time of the recording and reproducing of a magnetic recording and reproducing amplifier. CONSTITUTION:A waveform shaping unit 20 inputting a pulse signal outputted from a control signal generator 12 makes the rising and falling of the waveform of the signal gentle to output it. A voltage-to-current converter 21 outputs a current whose rising and falling are gentle to the base electrode of a switching transistor 11 by receiving the output of the waveform shaping unit 20. Since the base electrode of the switching transistor 11 performing a switching in order to reduce a crosstalk from a magnetic head and a rotary transformer, etc., is made of a current-driving the waveform of the rising and falling can be easily made gentle without increasing the input capacitance of the amplifier and therefore the hairnoise is reduced.

IPC: H01L21/58
Filed: 1985-01-18
Abstract: PURPOSE:To prevent partial high resistance or disconnection from being produced in a microstructure wiring layer by a method wherein a glass layer for the formation of metallized layers is formed on the upper surface of a ceramic-made pellet mounting substrate provided with a through-hole wiring layer with a wiring end on the upper surface so that the wiring layer may be formed with a roughly even thickness. CONSTITUTION:The lower end of a through-hole wiring body 8 belonging to a first layer substrate 2a is connected to an external terminal 1 by silver solder or the like. The upper end of a through-hole wiring 8a belonging to a second layer substrate 2b is exposed on the upper surface of the substrate 2b and, on the substrate 2b, a conductive layer 9 is formed, which is made for example of a nickel layer built by plating and is therefore equipped with poor wettability with glass. A glass layer 10 is formed to coat the upper surface of the second layer substrate 2b except the conductive layer 9. On the upper surface of the glass layer 10, metallized layers 11, 12 of aluminum are formed, produced by evaporation. With the upper surface being very smooth of the glass layer 10, the metallized layers may be even in thickness. Even when the wiring layer 12 is formed into a microstructure, an increase in resistance and wiring disconnection, which are apt to occur due to uneven thickness, may be prevented.
