Abstract: A tent frame binding device permitting speedy assembling and disassembling is disclosed. A binding body is provided with a plurality of slots angularly separated around it, and a pair of fastening recesses are formed at the side walls of each of the slots, the recesses being open upwardly. At the rear portion of each of the slots, there is formed an engaging step, and a frame member fastening part which is coupled with each of the slots is provided with a supporting shaft, the supporting shaft being coupled with the recesses of the slot. At the rear of the supporting shaft, there is formed an inclined portion which is to be coupled with the inclined engaging step of the slot. Tent frame members are inserted respectively into the holes of the frame member fastening parts, and the frame member fastening parts are assembled into the slots of the binding body.

Abstract: An electronic golf score counter for counting each fairway and putting stroke and totaling hole scores, total scores for the front nine holes, totals for the second or back nine, and the 18-hole totals. The counter has LCD displays and a plurality of switch keys for entering and displaying the hole number, its par value, the tee and fairway and putting strokes for each hole, and their totals. A reverse feature permits a count-down to a selected hole for a review of correction of a score. One embodiment provides a count for four players and includes an over/under par display for each.

Abstract: MOS Control circuitry for incorporation on a microcomputer IC chip for assuring adequate power to maintain the data in an associated static random access memory. A rechargeable battery provides standby power, and the voltage level of the battery is compared with the microcomputer V.sub.cc supply. Whenever V.sub.cc drops below a predetermined level, such as the standby battery voltage level, the circuitry disconnects the V.sub.cc from the memory input power and replaces it with standby battery power. When V.sub.cc is returned to the system, a gate applies a trickle charge to the battery.

Abstract: A regulated substrate bias voltage generating system for maintaining a minimum data retaining current through an associated MOS memory. The negative substrate bias voltage is generated by a charge pump operating under the control of a two-phased output oscillator, the operation of which is enabled and disabled by the output signals from a MOS memory over-current sensor, a MOS memory under-current sensor, and a bias voltage level sensor.
