Title: Cabinet for speaker
Inventor: OKINO NOBORU
IPC: H04R1/32
Filed: 1984-01-30
Abstract: PURPOSE:To reduce the disorder of an output sound pressure frequency characteristic by providing a subcabinet having baffle provided at least to one side of a main cabinet so that the surface of the baffle will be the same as that of the main cabinet in plane level. CONSTITUTION:The point different from the conventional one is that a subcabinet 5 is provided, for instance, at one side in the horizontal direction of a main cabinet 2a, so that the surface of a baffle will be the same as that of the main cabinet 2a in plane level. In such constitution, an acoustic space backward of a signal speaker 1 can prevent the odd-dimensional standing wave from generation. Since distances of diffracted sounds 11 and 12 up to a sound receiving point A are different in sound wave propagation as for the sound wave which is radiated forward from the speaker 1, the interference of a direct sound 10 and the diffracted sounds 11 and 12 is dispersed due to the different in the sound wave propagation distance of the sound wave transmission of the direct sound 10 and the diffracted sounds 11 and 12, and the disorder of an output sound pressure frequency characteristic is reduced.

IPC: H04B1/26
Filed: 1985-01-29
Abstract: PURPOSE:To perform all-wave reception in a single band by setting the local oscillation frequency of the 2nd mixing circuit to an intermediate frequency between the resonance frequency and antiresonance frequency of a solid resonator, and setting the 2nd intermediate frequency to a half as high as the difference frequency between the resonance frequency and antiresonance frequency of the solid resonator. CONSTITUTION:The 1st intermediate frequency amplifier 3 includes a low- impedance driving circuit for the solid resonator and a low-impedance passing circuit, so the highest amplification degree is obtained at the point of a resonance frequency fr where the series impedance of the solid resonator. A signal amplified by the 1st intermediate frequency amplifier 3 is supplied to the 2nd frequency converter 4, which mixes it with the output signal of the 2nd local oscillator 5 to obtain the 2nd intermediate frequency. When the 2nd local oscillation frequency is selected at a halfway point between the resonance frequency fr and antiresonance frequency fa of the solid resonator, the 2nd intermediate frequency Fif2 is fa-fr/2. This 2nd intermediate frequency is selected and amplified by the 2nd intermediate frequency amplifier 6 and demodulated by a detector 7 to obtain a low frequency signal.

Title: Data transfer error control system
Inventor: ABE HIROAKI
IPC: H04L1/16
Filed: 1987-01-23
Abstract: PURPOSE:To easily attain error control of data transmission by adding a data transmission request of other communication equipment to a reply status signal to one communication equipment from the other communication equipment after a data is transferred from the one communication equipment having priority to the other communication equipment. CONSTITUTION:A communication equipment 1 having priority neglects the transmission request of the communication equipment and transfers the transmission request to await a reply status signal from the communication equipment 4. Moreover, the communication equipment 4 applies processing to the transmission request from the communication equipment 1 with priority and sends a reply status signal of the transmission request to the communication equipment 1. In this case, based on the command from the control means, a transmission request is added to the reply status signal. Thus, the communication equipment 1 awaits the data reception from the communication equipment 4 while sending the reply status signal when the transmission request comes from the communication equipment in receiving the end reply status signal.

Title: Electronic watch
Inventor: KANNO FUMIO
IPC: H02P8/40
Filed: 1979-02-14
Abstract: PURPOSE:To obtain a multi-functional analog watch which is difficult to stop at low temperature by displacing the driving timings of two or more pulse motors to reduce the load of a battery. CONSTITUTION:A signal from a crystal oscillator 1 is supplied through a frequency divider 2 to the 1st drive circuit 3 for counting and through a delay circuit 2b to a day feeding 2nd drive circuit 4. The drive circuit 3 generates drive pulses at every two seconds with phase difference of one second from its output terminals 3a, 3b to a pulse motor 5 so as to this move a hand. On the other hand, the drive circuit 4 generates similar drive pulses delayed from the output terminals 4a, 4b to a pulse motor 15 so as to thus rotate a day feed wheel 21. Thus, since the drive pulses are displaced in phase with each other, even if two pulse motors are used, it reduces the load to the battery 50 which is difficult to stop it at low temperature.

IPC: G08G1/015
Filed: 1978-02-13
Abstract: PURPOSE: To make it possible to identify the kind of a vehicle accurately by measuring the time from an ultrasonic transmission wave to its reflected reception wave and by discriminating it by a microprocessor.  
     CONSTITUTION: An ultrasonic signal from ultrasonic-wave generator 101 is transmitted from transmitter-receiver 105, reflected by a road surface, small-sized vehicle, or large-sized vehicle, and then received by transmitter-receiver 105, so that it will be clocked by external counter 110. To detect a large-sized vehicle such as a bus, microprocessors 120A and 120B store in RAMs 123A and 123B ultrasonic-wave return times between discriminative inferior level HA for a vehicle highser than a small-sized vehicle and the road surface, and between superior level HB higher than the bus and road surface in addition to a reference time through the reflection from the road surface. Then, detecting a reflected wave from a higher part than level HA cause microprocessor 120A to output detection signal DA, and detecting a reflected wave from a higher part than level HB, on the other hand, causes 120B to output detection signal DB; and EOR circuit 129 outputs OR-ELSE signal DS between both the outputs, thereby detecting the bus.

IPC: H03K23/66
Filed: 1982-02-03
Abstract: PURPOSE:To eliminate limit to a using clock frequency, by setting the down- switch timing of a presettable up-down counter with the constant of a pattern detecting circuit. CONSTITUTION:A sequence pulse generating circuit 23 produces a latch pulse La and a load pulse Lo when an input signal V arrives. As a result, a latch circuit 22 applies the output Qi of a presettable up-down counter 11 to a preset input terminal Di of the counter 11 with a shift given to the output Qi by a bit toward the lower direction. Now if the counter 11 is counting up, a pattern detecting circuit 21 delivers a coincidence pulse when the contents of the counter 11 are set at the fixed value K. Thus an FF24 is reset, and the counter 11 is changed to a down-count mode. Then a carry CRY is delivered from the counter 11 when its down-count operation advances. Thus the FF24 is set to set again the counter 11 in an up-count mode. Then the circuit obtain an oscillating output OUT by repeating the above-mentioned operations.

Filed: 1984-01-31
Abstract: PURPOSE:To obtain the titled inexpensive alloy having superior wear resistance, high effective permeability and high saturation magnetic flux density by specifying a composition consisting of Si, Al, C, W and Fe. CONSTITUTION:This wear-resistant alloy having high magnetic permeability consists of, by weight, 6-11% Si, 4-8% Al, 0.01-0.5% C, 0.02-1.0% W and the balance Fe. When the alloy is used as the material of the core of a magnetic head, strong leakage magnetic flux is provided even in case of a narrow gap, and the core can be obtd. at a low cost because no noble metal is contained. When the amounts of Si and Al are below the lower limits or above the upper limits, the magnetic characteristics, especially the effective permeability are remarkably deteriorated. When the amounts of C and W are below the lower limits, C and W are not well effective in improving the wear resistance, and when the amounts of C and W are above the upper limits, the effective permeability is reduced.
