Title: Driver for dc brushless motor
IPC: H02P6/08
Filed: 1992-03-24
Abstract: PURPOSE:To simplify calculation and to reduce memory capacity by setting the period of synchronizing signal in step with time thereby producing a synchronizing signal having a set period. CONSTITUTION:Upon receiving a command signal 151, period setting means (PS) 101 reads out a period T1 and a period sustaining time t1 from a memory 103 and sets the period T of synchronizing signal at T1. A synchronizing signal output means (SO) 104 produces a synchronizing signal having period T1 and a timer 102 begins to measure the time. When the timer 102 measures a time t1, the PS 101 reads out a period sustaining time t2 for next period T2 from the memory 103 and sets the period T at T2. The SO 104 produces a synchronizing signal having period T and the timer 102 begins to measure the time t2. When the timer 102 measures the time t2, the PS 101 sets the period T at T3 and the SO 104 produces a synchronizing signal having newly set period. In similar manner, period of synchronizing signal is reduced in step with time.

Title: Manufacture of reinforcing article
Inventor: JIEEMUZU BURATSUDOREI NIZURII
IPC: B29C33/12
Filed: 1981-04-30
Abstract: A reinforcing cord is positioned in a mold cavity for reinforcing an annular article such as a tire by wrapping the cord on an annular spacer band which is supported on a mold core and then placed in the mold. The mold is charged with a liquid polyurethane reaction mixture to form an outer polymeric ring of the annular article which is adhered to the cord and partially cured. The spacer band is removed, the mold closed and charged with additional liquid polyurethane reaction mixture to form an inner polymeric ring of the annular article adjacent the reinforcing cord carried by the outer ring. The partially cured outer ring and the inner ring are then cured to adhere the inner ring to the outer ring with the layer of reinforcing cord encapsulated between the rings. An additional layer of reinforcing cord may be positioned in the article by wrapping another cord around a second spacer band having a smaller diameter than the first spacer band. The second spacer band is placed in a mold and defines a cavity between the spacer band and the outer ring. The mold is then charged with additional liquid reaction mixture to form the second polymeric ring and encapsulate the cord on the second spacer ring and partially cure the second ring for adherence to the first ring. The second spacer band is then removed and the mold charged with additional liquid reaction mixture to form the radially innermost third polymeric ring. The reaction mixture of the second and third rings are then cured to provide adherence between the adjacent rings.

Abstract: PURPOSE:To improve the frequency characteristics and to reduce a collector saturation resistance of a semiconductor device by equalizing or enhancing the impurity concentration of a bipolar transistor forming region to or higher than that of a P-channel MOS transistor forming region. CONSTITUTION:An N<+> type buried layer 3 and P<+> type buried layers 4, 4A are formed on a P-type semiconductor substrate 1, an N<+> type epitaxial layer 2A is formed thereon, and a P<+> type wall layer 5 and a P<+> type layer 6 for dielectric isolation are formed in the layer 2A. An N-channel MOS transistor is formed on the layer 5, and P-channel MOS transistor and a bipolar transistor are formed in the P-channel MOS transistor and the bipolar transistor forming regions in the layer 2A. Thus, since the bipolar transistor is formed in the N<+> type epitaxial layer having the same high impurity concentration as that of the P-channel MOS transistor forming region, frequency characteristics are improved, and a collector saturation resistance is reduced.

IPC: C07C231/12
Filed: 1982-04-22
Abstract: PURPOSE:To obtain methacrylamide in high yield with suppressed side reactions, by heating an alpha-oxyisobutyric acid amide in the presence of a solid acidic catalyst. CONSTITUTION:An alpha-oxyisobutyric acid amide is heated in the presence of a solid acidic catalyst to give methacrylamide.

However, the above-mentioned catalyst provides the aimed compound without causing unfavorable decomposition or polymerization due to the dehydration reaction.

Title: Simultaneous transmission-reception system for radio equipment
Inventor: AKITA HIROYUKI
IPC: H04B1/56
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To widen the transmission/reception frequency intervals of respective transmission/reception filters, to narrow the frequency bands of passing and attenuating areas in charge and to lower an insertion loss by dividing the transmission-reception filter of an antenna multicoupler into those of respective bands. SOLUTION: According to the command from a base station A (channels 1 to 49), a first antenna multicoupler 3 is operated in the upper frequency band and set on standby. When the frequency of calling due to a telephone set call is increased in that the calling band area and calling is turned into difficult state, the command 'to switch over to lower frequency band' is issued from a base station B (channels 50 to 100) through an antenna 1, first antenna multicoupler 3, changeover switch 6, and reception part 8 to a control part 10. For the presence or the absence of the command, if the command's presence is detected, the changeover switch is thrown to the lower frequency band, and switching to a second antenna multicoupler 4 is performed.  On the other hand, the second antenna multicoupler 4 is thrown to the lower frequency band and set on standby, if there is a command 'to switch to upper frequency band'. These steps are successively repeated.

Filed: 1985-03-30
Abstract: PURPOSE:To simply start a gas laser device in a short time and to reduce power loss by applying a high voltage pulse voltage at the prescribed time interval when a gas laser oscillator is started. CONSTITUTION:A gas laser oscillator has a discharge space 34 formed between a grounded anode 31 and a cathode 33 made of many pin electrodes 33a-33n. The electrodes 33a-33n are connected through ballast resistors 32a-32n with a high voltage pulse power source 23. A controller 21 applies a control signal S1 to a pulse generator 22 to generate a pulse train S having the prescribed time width and interval when the oscillator is started, and supplied to a pulse power source 23. The power source 23 generates high voltage pulses P1-P2 in response to a pulse train S2. A leakage resistance 35 between the electrode 33a and the anode 31 started by the pulse P1 is smaller than that between the pin electrode not initiated for a discharge and the anode 31; therefore, when a pulse P2 is applied, the pin electrodes except the electrode 33a starts discharging. When he all pin electrodes are started for discharging by the prescribed repetition of the pulses P1-P2, it is shifted to a rated operating DC voltage P3.
