Title: Brushless motor control and device thereof
Inventor: SHINOZAKI YOSHITERU
IPC: H02P6/182
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To simplify the position detection circuit of a rotor in a brushless motor, detect the position of the rotor accurately, switch current-carrying of an armature winding current properly, and improve efficiency. SOLUTION: The armature winding voltage of a brushless motor 4 is divided by the first voltage dividing circuit 10a. The divided winding voltage which is divided is divided by the second voltage dividing circuit 10b. The divided winding voltage at respective phases which is divided by the first voltage dividing circuit is compared, by a comparison circuit 10c, with 1/2 winding voltage at the remaining phases which is divided by the second voltage dividing circuit with combinations of 6 sets. By six comparative results obtained by the comparison circuit, the time of intersection of the respective divided winding voltage with 1/2 divided winding voltage is detected.  Based on the difference between the detection intersection time and the previous intersection time, a time T30 corresponding to a phase of 30 degrees is calculated, correction is conducted for the time T30 according to the application of the brushless motor and present number of revolutions, and the current-carrying switching of the brushless motor is controlled at the elapsing time of the time T30 from the detection intersection time.

Title: Production of conductive sheet
Inventor: NAKAMURA HIDEMARO
IPC: C08L27/06
Filed: 1995-03-14
Abstract: PURPOSE: To prevent the generation of a small hole by kneading a conductive powder with a vinyl chloride resin to obtain a master batch and compounding the master batch with a vinyl chloride resin and subjecting the obtained compd. to calender molding. CONSTITUTION: A conductive powder and a vinyl chloride resin compsn. are kneaded by a kneader and formed into pellets by a roll or an extruder to form a master batch and a vinyl chloride resin is compounded with the master batch in a ratio of about 0.2-2.0:1 and the obtained compd. is subjected to calender molding to form a conductive sheet with a thickness of 0.2-0.1mm. At the time of the production of this sheet, a small hole is hard to generate. In calender roll molding, a taking-up ratio is made large as the thickness of the sheet is reduced in order not only to increase productivity but also to prevent the deterioration of a resin caused by the excessive shearing applied to the resin.

Title: Malfunction preventing system for fsk communication
Inventor: KAMEI SABUROU
IPC: H04L27/14
Filed: 1980-06-19
Abstract: PURPOSE:To prevent the malfunction due to noise, by adding the front and post carriers to a FSK signal, and switching the gate of AND circuits within the present period of the front and post carriers. CONSTITUTION:An FSK signal added with front and post carriers is applied to a zero crossing amplifier circuit 2, comparators 3, 4, integrator 6, comparator 7, and FF10 via a BPF1. When the FF10 is set, the output of the circuit 2 is applied to a demodulator 12 and a logical processing circuit 13. The circuit 13 outputs a reception confirming signal g and resets the FF10 after the processing time. The signal g is the timing signal before the stop of the post carrier, but since the FF10 has the priority for reset, an AND circuit 11 is closed. Thus, the malfunction due to noise after the stop of the post carrier can be prevented.

Title: Semiconductor device
Inventor: NOGUCHI HIDEO
IPC: H01L23/28
Filed: 1984-04-25
Abstract: PURPOSE:To improve the element characteristics of chip by a method wherein means to relieve the stress on a chip are taken on the backside of package main body excluding the part opposing to the chip. CONSTITUTION:Means to relieve the stress on the chip are taken on the backside of package main body excluding the part opposing to the part near chip. For example, the film thickness of package main body 21 separated from a chip 1 is made thinner while the film thicknesses of upper and lower parts of package main body 21 are made equivalent to each other. Through these procedures, the fulcrums of stress when the package main body 21 is warpted are divided into three points i.e. P1 as the central point of chip 1, P2, P3 as the points on the marginal lines where the film thickness of package main body 21 begins to change. Resultantly the characteristics of chip 1 may be prevented from deteriorating since the stress on the chip 1 when the package main body 21 is warped by any ambient environmental change may be reduced to the minimum.

Title: Polymerization by microwave heating
Inventor: NISHIZAWA AKIRA
IPC: H05B6/80
Filed: 1990-03-30
Abstract: PURPOSE:To polymerize a radical-polymerizable polymeric monomer by heating chiefly the monomer only by applying the monomer to the surface of a substrate or packing it into a mold and applying radiofrequency waves thereto. CONSTITUTION:A radical-polymerizable polymeric monomer is applied to the surface of a substrate or packed into a mold and is polymerized by applying radiofrequency waves to the monomer to heat chiefly this monomer only. According to the above process, the polymeric monomer is radical-polymerized by applying radiofrequency waves of, for example, 1GHz to an unpolymerized polymeric monomer, so that the polymerization can be accomplished without being affected by the contained fine inorganic powder such as a magnetic powder or carbon black which interrupts the transmission of light. Further, when the polymeric monomer is applied to a magnetic tape susceptible to heat, the monomer can be selectively heated. Therefore, a high-quality magnetic tape can be produced inexpensively.
