Title: Manufacture of molded coil
Inventor: TAIRA SATORU
IPC: H01F41/12
Filed: 1986-10-29
Abstract: PURPOSE:To improve the heat dissipation property of a coil by forming the coil by continuously winding a partially heated coil conductor in a state of high temperature on a prepreg sheet insulating paper wherein an impregnated thermosetting resin is made into a semi-hardened state. CONSTITUTION:A coil conductor 1 is sent to a coil bobbin 6 after heated by a coil conductor heating device 7. A prepreg-treated interlayer insulating paper 2 is previously wound on the coil bobbin 6 and the coil conductor 1 is wound on the interlayer insulating paper 2. The resin of the interlayer insulating paper 2 is softened by the heat of the coil conductor 1 since the coil conductor 1 has already been heated. Further, a tension given to the coil conductor 1 makes the softened resin to be pushed to both sides by the coil conductor 1, buries the coil conductor 1 in the resin and in this way, the coil conductor 1 is wound. This almost prevents an air layer from being involved in a coil and the heat dissipation property of the molded coil is improved.

Title: Variable delay circuit
Inventor: HASHIMOTO JUN
IPC: H03K5/13
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To obtain fine delay application less than the propagation delay amounts of a logical circuit element without using any analog circuit element by providing an opening and closing gate for preventing the passage of an input pulse signal at one logical circuit element. SOLUTION: An AND gate 4 is gate opened and closed according to the setting condition of a register 10. Propagation delay amounts Tpd2 at the AND gate 4 side are made larger than propagation delay amounts Tpd1 at a buffer 3 side. When the AND gate 4 is closed, a pulse at a path 1 side only is outputted, and an output pulse with delay amounts Tpd1+Tpd3 obtained by the buffer 3 and the OR gate 6 is outputted. When the gate of the AND gate 4 is opened, an output pulse is obtained by OR adding the both pulse signals with the delay amounts Tpd1 obtained by the buffer 3 and the delay amounts Tpd2 obtained by the AND gate 4 by an OR gate 6. The pulse width of the output pulse can be widened, and the tail position of the pulse can be the output pulse delay-increased only for the delay amounts Tpd2-Tpd1.

Title: Horizontal synchronizing generating circuit
Inventor: ARAI IKUYA
IPC: H04N9/44
Filed: 1987-10-16
Abstract: PURPOSE:To always obtain a signal processing pulse synchronizing with an input video image by decoding the content of a horizontal counter at a prescribed value to reset the horizontal counter by a pulse generated from a horizontal synchronizing clock at the time of non-standard state. CONSTITUTION:When an input video signal is switched from a standard signal into a non-standard signal at a time A, the frequency is changed for a synchronizing signal (a). A nonstandard signal detection signal (b) is retarded by a detection time of the non-standard detection circuit 114 and when the signal becomes the nonstandard signal detection signal from the standard at a time B, a system clock C is switched from a clock 4fSCB into a clock fSCH. In this case, an output pulse (d) of a 1/910 frequency division circuit 113 is synchronized with the synchronizing signal (a) at all times. On the other hand, a 910 decode pulse (e) keeps the pulse phase of the standard signal till the time B and then in phase with the signal (d). The reset pulse (f) is switched from the signal (e) into the (d) at the time B.

Title: Junction type field effect transistor
Inventor: KAWAI HIROHARU
IPC: H01L29/80
Filed: 1986-10-31
Abstract: PURPOSE:To make it possible to perform power amplification up to a 10 GHz band, by laminating a drain region, a gate region and a source region, providing a low-concentration or intrinsic semiconductor layer between the drain region and a gate region, and forming a channel region at a side surface crossing the laminated layers. CONSTITUTION:A first-conductivity type drain region (substrate) 1, a secondconductivity type gate region 3 and a first-conductivity type source region 5 are formed in a laminated pattern. A low-concentration or intrinsic semiconductor layer 2 is provided between the drain region 1 and the gate region 3. A channel region 7 is formed at a side surface crossing the laminated layers of the drain region 1, the low-concentration or intrinsic semiconductor layer 2, the gate region 3 and the source region 5. Because of the very short length of the gate and reductions in gate capacitance, gate resistance and source resistance, an ultimate structure, in which element characteristics are determined with the transition speed of electrons, is obtained. The distance between the gate and the drain is made long and a high output impedance state is formed so as to provide breakdown strength. Thus power amplification up to a band of several tens of GHz can be performed.

Filed: 1984-12-11
Abstract: PURPOSE:To realize a plan for carrying out speed change operation with no clutch by providing two reducers adjacently in a line between the input and output sides of a change gear and connecting either of the reducers with the input and output sides in an alternative way. CONSTITUTION:Each of individual oil hydraulic clutches C0, C1 is provided between two reducers R1, R11 arranged in a line. When either of them is turned ON, the other is turned OFF, power is therefore transmitted in an alternative way, namely, directly or at speed reduction ratio i. On the other hand, two oil hydraulic clutches C2 are provided between reducers R2, R22 arranged in a line. When either of them is turned ON, the other is turned OFF, power is therefore transmitted in an alternative way, namely, directly or at speed reduction ratio i<2>. Thus speed change operation can be carried out in an ON- OFF control system using ON and OFF signals for control signals without operating a clutch by a foot.

Title: Address decoder circuit for non-volatile memory
Inventor: ARAKAWA HIDEKI
IPC: H01L21/8247
Filed: 1988-10-15
Abstract: PURPOSE:To attain erasing for 1 bit of EPROM without increasing the number of elements by making the potential of the terminal of the logical gate part of a decoding part and a buffer circuit part prescribed at the time of an erasing mode, making an output polarity different at the time of writing and reading and outputting the erasing stopping potential at the time of the non-selection. CONSTITUTION:At the time of the erasing mode, to a first terminal Va of the logical data part of a decoder formed by a transistor (TR)Ql for load with a different conducting type and TRQ1 to Qn in which an address is supplied to the gate, a potential 0V different fro power source potentials Vcc and Vpp given at the time of writing and reading is impressed, and to a second terminal Vb, a potential Vcc is supplied. Simultaneously, to a third terminal of TRQb with different Vcc is supplied. Thus, at the time of the erasing mode, the voltage is not outputted at the time of selecting and at the time of non-selecting, the voltage to stop the erasing is outputted. Consequently, at the time of selecting, the negative voltage is impressed to a word line and the erasing for 1 bit due to the negative voltage can be executed without increasing the number of elements.
