Title: Analog/digital converting circuit
Inventor: KATAGIRI TAKASHI
IPC: H03M1/56
Filed: 1991-04-15
Abstract: PURPOSE:To reduce the cost of an A/D conversion circuit by composing the A/D conversion circuit with a comparator and peripheral equipments only. CONSTITUTION:A velocity commanding voltage 7 is turned to an LPF output 71 removing a higher harmonic component by passing through an LPF(low pass filter) 1. A comparator 2 compares the LPF output 71 of the voltage 7 with a triangular wave 8 having a fixed frequency and a fixed amplitude. In the output 71, a level position to cross the triangular wave 8 is made different corresponding to the level. Therefore, the output of the comparator 2 is turned to a pulse width modulation signal 9 corresponding to the level of the output 71. A microprocessor 3 calculates deviation between a digitally converted velocity commanding value and the revolution speed of a motor 5 from an encoder 6 and controls an inverter 4 so that the deviation can be zero.

Title: Lever operating mechanism
Inventor: ENDOU SADAYOSHI
IPC: G11B15/44
Filed: 1981-07-16
Abstract: PURPOSE:To improve the operability, by shaking a shaking section on a shaking member when either a fast feed lever or a rewinding lever is pushed, and operating a reel stand in fast feed or rewinding. CONSTITUTION:Through the depression of a fast feed (FF) lever 5 or a rewinding (REW) lever 6, contact parts 28 and 29 of the levers 5 and 6 are contacted with the 2nd control member 25 to push the 2nd control member 25. As a result, since a control section 26 of a member 23 moves right a latch pin 24 of the member 23 along a taper, components such as a magnetic head held on the control member 23 are released from the playing state and retrogressed. Thus, a tape on a reel stand 4 is made for the fast feed operation only for either FF or REW.

IPC: H02K21/12
Filed: 1985-05-24
Abstract: PURPOSE:To reduce the magnetic saturation in stator teeth by varying to increase the width of stator teeth formed on both sides of a radial winding slot of a stator core for containing an armature winding as the function of a radius from the radial inside toward the outside. CONSTITUTION:The width (t) of stator teeth 14 formed on both sides of a radial winding slot 12 of a stator core 10 for containing an armature winding is varied to be increased as the function of a radius from the radial inside of the core 10 toward the outside.

Title: Primary radiator for shf receiving parabolic antenna
Inventor: INOUE NOBUTAKA
IPC: H01Q19/13
Filed: 1987-05-06
Abstract: PURPOSE:To improve the efficiency of the utilization of a reflector mirror by decreasing an overflowing radiation, and at the same time, making the reflector mirror to receive efficiently any of a signal, coming as being reflected from its central part or the signal, coming as being reflected from its peripheral part. CONSTITUTION:The SHF signal, coming from the transmission equipment of the SHF signal and reflected by the reflector mirror 4, is converged toward the focus of the reflector mirror 4, and the converged SHF signal is accepted to a horn 15 in a primary radiator 7. In this case, since the reflecting surface 16 for suppressing an overflowing radiation is formed around the opening end of the horn 15, and a cylindrical body 18 for suppressing the overflowing radiation is provided in the circumference of the said reflecting surface 16 ahead the said reflecting surface, the radiation pattern of the primary radiator 7 comes to be a shape, in which the overflowing radiation comes less. Accordingly, the primary radiator 7 comes difficult to accept the signal from the direction other than the reflector mirror 4, and besides, at the same time, it receives efficiently the SHF signal, reflected by any of the central part and the peripheral part of the reflector mirror 4. Thus, the overall surface of the reflector mirror can be efficiently utilized.

IPC: B21J1/04
Filed: 1988-05-09
Abstract: PURPOSE:To form the central part of a slab into a rectangular shape with a thin thickness or a dog bone shape by dividing the total edging amount being a target value and performing plural pressings by a small drafting amount per slab transfer. CONSTITUTION:A tapered face 4 slant in a divergent shape from a nearly central point to the press inlet side is formed on a pressing face of right and left metal dies 2, 3 so that a formed part of a slab 1 is sequentially deformed in a long rhombic shape in the transfer direction of the slab 1 and the dies 2, 3 are moved forward by a prescribed drafting amount. In edging, for example, the total edging amount is divided into three amounts and edging by a one-third draft is performed three times. Thus, respective draft amounts (a), (b), (c) are reduced, so that deformation amounts I, II, III of the slab 1 is also reduced. As the result, a bulging amount at both end parts in the cross direction of the slab 1 is increased and a bulging amount at the central part is reduced, so that a sectional shape of the slab 1 is formed into a nearly rectangular or a dog bone shape.

Abstract: PROBLEM TO BE SOLVED: To prevent communication from being omitted by the behavior of an aircraft even in the case of requiring to use the antenna of sharp directivity by preserving transmission data in a storage means in the case that a reception state is deteriorated and transmitting the transmission data in the case that the reception state is restored. SOLUTION: In the case of judging that the reception state is deteriorated from the reception state set beforehand in a transmission control means 4, the transmission control means 4 reports signals for stopping transmission to a transmission buffer 1. At the time of receiving the report, the transmission buffer 1 temporarily preserves the transmission data in the transmission buffer 1 and interrupts the transmission of the data to be sent to a transmitter 2. When the reception state is restored, the transmission control means 4 sends the signals for permitting the transmission to the transmission buffer 1 and the transmission buffer 1 sends the transmission data preserved until then to the transmitter 2 first and restarts the transmission of the data.

Filed: 1982-06-28
Abstract: PURPOSE:To emit light in a wavelength region approximating to a light-emitting diode of a GaAsP group, to eliminate the need for a diffusion process, to emit a high radiant power output and to enable fining by liquid-growing a second GaAlAs epitaxial layer, a conduction type thereof is reverse to a GaAs substrate and thickness thereof is a specific value or less, onto a first GaAlAs epitaxial layer so as to function as a diode. CONSTITUTION:Zinc is diffused from the surface of a wafer 23 while using insulating films 24 as masks, and p type isolation regions 25 reaching the p type GaAlAs layer 21 are formed. The n type GaAlAs layer 22 is divided by the p type isolation regions 25 at that time, and independent n type island regions 26a, 26b... are formed. p-n junction surfaces among the n type island regions 26a, 26b... and the p type GaAlAs layer 21 function as light-emitting regions. Zinc need not be diffused deeply at that time because the n type GaAlAs layer 22 is sufficiently thin (not more than 10mum). Accordingly, extents in the lateral direction of the p type isolation regions 25 are extremely small in the diffusion process.
