Title: Automatic defection of short circuit of speaker for automobile audio device
Inventor: KROCHMAL ANDREW CYRIL
IPC: G01R31/02
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To detect the interconnection of a speaker during the assembly process of an automobile automatically by providing a detector at an audio-processing part including, for example, a microcontroller and a power amplifier with a logic circuit for feeding a diagnosis signal to the audio-processing part. SOLUTION: Power amplifiers 11 and 14 output a clip detector output and a diagnosis signal and drive left and right stereo speakers 12, 13, 15, and 16. An audio-processing part 10 has an audio source 17 such as a radio tuner. An audio signal from the audio source 17 is inputted to a digital signal processor(DSP) 20 for outputting left and right stereo signals. A microcontroller part(MPU) 21 communicates with the DSP 20 and the audio source 17 and controls the operation of an audio device. The MCPU 21 receives an input command from an input 22. A display 23 is connected to the MCU 21 and displays the state of the audio-processing part 10, thus adjusting audio parameters such as volume, balance, and fade.

Title: Gas meter
Inventor: HOTTA TADAO
IPC: G01F3/22
Filed: 1987-11-24
Abstract: PURPOSE:To reduce the cost and to improve the reliability by generating electric pulses at each constant flow rate and receiving and converting them into unit flow rate pulses, and powering on a center device when the value obtained by subtracting them from a constant value decreases below a specific value. CONSTITUTION:A gas supplier 3 when changing gas cylinders sets and stores a constant value equivalent to cylinder capacity in a rest control circuit 15 in a gas meter by using a setter 25. When a consumer 1 uses gas, the gas flows through the meter 13. A flow rate sensor 14 generates an electric pulse (flow rate signal) at every constant flow rate of the passing gas, the pulse is converted by a flow rate arithmetic circuit 26 into a unit flow rate pulse, and this unit flow rate pulse, i.e., gas consumption is subtracted from the constant value stored in the circuit 15; when the value reaches the specific value, e.g., zero, the circuit 15 outputs a no-rest signal. This signal is inputted to the computer 4 of the supplier 3 through a terminal unit 16, an information unit 19, a subscriber line 2, and an interface 9 and the data is processed by using software 8. The cylinders are changed according to the information.

Abstract: PURPOSE:To obtain an exothermic body generating high temperature heat with a small amount of heating current, and high in the uniformity of thermal distribution over an exothermic surface by overlapping two or more exothermic sheets having the predetermined heating current passage within the surface in parallel with a gap. CONSTITUTION:The flat type exothermic body in the title is constituted with three exothermic sheets 1a to 1c overlaid in parallel with a gap, conductive connection pieces 3a and 3b, and insulating support pieces 4a and 4b. In this case, the current flow passages 2a and 2b of the exothermic sheets 1a to 1c make self-heat generation due to the Joule heat of heating current, and the exothermic sheet 1a receives auxiliary heat from the exothermic sheets 1b and 1c, in addition to self-heat generation. As a result, the exothermic sheet 1a becomes high in temperature with a low heating current value, compared with the case of independent heat generation. Also, the slit 21a of the exothermic sheet 1a and the flow passage 2b of the exothermic sheet 1b are orthogonal with each other, and heat is emitted from the exothermic sheet 1b to the exothermic sheet 1a through the slit 21a of the exothermic sheet 1a, thereby homogenizing substantially the heat emitted from the exothermic sheet la. According to the aforesaid construction, it is possible to obtain a flat type exothermic body 10 of flat temperature distribution and excellence in uniform temperature quality.

Abstract: PURPOSE:To eliminate an influence of connection of a slow-access peripheral upon the operation of a CPU by providing two busses of a memory bus and a peripheral bus with a buffer circuit between them and controlling the transfer speed of each bus for DMA transfer by a DMAC (direct memory access controller). CONSTITUTION:A memory bus 2 to which a CPU 1 and a memory 5 are connected and a peripheral bus 9 to which plural peripherals 6 and 7 are connected are provided with buffer circuits 26 and 27 between them. They are controlled by a DMAC 8 so that the transfer speed of the memory bus 2 is adapted to the memory 5 and that of the peripheral bus 9 is adapted to peripherals 6 and 7 as the transfer object at the time of DMA transfer. Consequently, the time when the memory bus 2 is monopolized by the DMAC 8 at the time of DMA transfer is shortened though peripherals 6 and 7 of slow access are connected to the peripheral bus 9.

Abstract: PURPOSE: To attain excellent ice traveling performance without reducing snow traveling performance by forming a slant groove by low and high slant grooves in the center area of a tread, and substantially circumferentially continuing a block just under a load by a slender groove provided on a part thereof which is closed just under the load. CONSTITUTION: Blocks 5, 6 having sipes 7 are formed by slant grooves 2, 3 in the center area TC of a tread partitioned by a circumferential groove 1, and the negative ratio is set to 20-30%. The slant grooves 3, 2 have inclinations of 40 deg. or more and less than 50 deg. to the circumferential direction, respectively, the relatively large block 5 has such a slender groove 4 less than about 1mm that it is closely adhered just under a load, the slender groove 4 is closed just under the load, whereby the blocks on both side parts are closely adhered and substantially continuously extended in the circumferential direction.  Thus, the circumferential groove 1 ensures the grip force in the tire transverse direction, the slant grooves increase the transverse lateral grip force and have an edge effect on the vertical direction, and ice traveling performance can be improved with hardly reducing snow traveling performance.

Abstract: PURPOSE:To prolong the service life of a scanner driving system and to reduce power consumption by independently controlling the driving start of the scanner driving system in accordance with a printing mode which is instructed and inputted. CONSTITUTION:A controller 3 actuates a motor control circuit 6 or a motor control circuit 7 based on the instruction. When the motor control circuits 6 and 7 revolve only one motor, that is, a mode to revolve a motor 8, an inputted control signal 5 is kept as it is, and only a control signal 4 is made active. The motor control circuit 6 causes the motor 8 to start revolving. Therefore, a designated rotary polygon mirror alone starts rotating. Thereby, the driving system service life can be extended and power consumption can be reduced.
