摘要:
The universal product code consisting of black bars and white spaces carrying information is discriminated by counting the occurrence period of electric signals corresponding to the guard pattern and averaging the count obtained thereby to provide a width information of the basic module, discriminating the first character by sampling the code in stop-start synchronization based on the width information, counting the occurrence period of electric signals corresponding to the (n-1)th character to provide another width information of the basic module from the count obtained thereby, and discriminating the n-th character by sampling the code in stop-start synchronization based on the basic module. Therefore, a high performance code discriminator can be achieved by a simple structure.

There is provided a time setting and displaying mode control circuit for an electronic timepiece comprising first and second switches, first and second detection circuits responsive to the operative conditions of the respective first and second switches and first and second ring counters each including a plurality of shift registers and respectively connected to the first and second detection circuits to produce time setting and displaying mode signals, respectively.The content of the first ring counter is shifted in response to an output signal produced from the first detection circuit each time the first switch is depressed in the time setting mode. The content of the second ring counter is shifted in response to an output signal produced from the second detection circuit each time the second switch is depressed in the time displaying mode. When the first switch is depressed under the "hour-minute" displaying mode, the content of the first ring counter is changed to provide the "hour" setting mode. Further, when the first switch is kept depressed for more than two seconds in the time setting mode, all the shift registers of the first ring counter are reset to permit the second shift register to provide the "hour-minute" displaying mode.

A golf club includes a shaft and a head. The golf club has a shaft mass Ms of 60 g or less and defines a head mass Mh(g) and the shaft mass Ms(g) to have a relation to satisfy the following expressions (A) and (B): Mh≧Ms+155 (A) Mh≦−0.14·Ms+240.9 (B)
摘要:
A working vehicle comprises a working implement (20) supported by the working vehicle to be displaceable by a hydraulic actuator (1), and a controller (16) for generating a control output signal for controlling a position of the working implement in response to a control input signal, with reference to predetermined control characteristics. The control characteristics include at least a first control characteristic (Qs′) and a second control characteristic (Qs″) different from each other. The controller refers to the second control characteristic for generating the control output signal when the control input signal results from a variation in a set signal from a setter (15; 17S) for setting a target level of the working implement, and refers to the second control characteristic for generating the control output signal when the control input signal results from a variation in a detection signal from a displacement detecting sensor for detecting a displacement of the working implement.

A silver halide photographic light-sensitive material includes a compound selected from: (1) a quaternary nitrogen or phosphorus salt compound, having 20 or more of total recurring units consisting of an ethyleneoxy group and/or a propyleneoxy group; (2) a quaternary salt compound represented by formula (A): wherein Q represents nitrogen or phosphorus, R1, R2 and R3 represent an alkyl, aryl, alkenyl, alkynyl, or heterocyclic group, L1 represents an alkylene group, Y represents —C(═O) or —SO2—, L2 represents a divalent connecting group having at least one hydrophilic group, Xn− represents an n-valent counter anion, n being an integer of 1 to 3; and (3) a quaternary salt compound represented by formula (B): wherein A represents an organic moiety necessary to complete a nitrogen-containing aromatic heterocyclic ring. L2 represents a divalent connecting group having at least one hydrophilic group that divides L2. L1, Y and Xn− have the same meanings as above.
摘要:
In the case where a heater main body (1) is bent so as to be wound around a subject to be heated such as a water pipe, etc., a heater can stably heats the subject to be heated. A plurality of heating elements (2), which are composed of ceramics as positive-characteristic thermistors and have electrodes on both sides of the heating elements, are sealed along a lengthwise direction of the heater main body (1) with flexibility and electrical insulation at intervals. Pairs of feeders (3) for feeding electricity to the heating elements (2) are provided to the heater main body (1). A holder (5) having electrical conductivity is provided into the heater main body (1) so as to connect the heating elements (2) to the feeders (3) and retain them. The holder (5) reduces faulty electrical connection between the feeders (3) and the heating elements (2), and thus the heat generation by the heating elements (2) can be stabilized.
