摘要： PURPOSE:To provide an apparatus capable of measuring the dynamic injection timing of an engine without detaching various parts attached to the engine, by providing a detector attached to the outside of a part used in the injection system, a circuit for processing the output of said detector, a timing light, a Braun tube oscilloscope, etc. CONSTITUTION:A vibration detecting sensor 4 is attached to the portion of a lock nut used for fixing injection pipe 2 to injection nozzle holder 3. The output of this sensor 4 is afforded via amplifier 5 and band-pass filter 6 to oscilloscope 13 capable of measuring two phenomena, which represents waveform 1. After the waveform is shaped by detector 7 and comparator 8 added with reference voltage setter 11, the voltage is applied to trigger voltage generator 10 for energizing luminous discharge xenon tube 12. The voltage change across the two electrodes of this lumiuous tube 12 is represented as waveform 2 in oscilloscope 13. With such an arrangement, delay circuit 9 is controlled to conform the above two waveforms 1, 2 with each other for detecting the dynamic injection timing by reading crank angle indicating graduation 14 at the time when the two waveforms are conformed.

CONSTITUTION: A stepladder for a garden plant is provided with a fixing member 46 to fix a garden plant fixing 40 and a ladder part 20, a protective part 60 arranged in the ladder part 20, an aerial scaffold 70, a shears housing part 80 hooked and installed on an engaging part and a safety belt 110 fixed to the ladder part 20. Therefore, overturning by force from the horizontal direction at work is prevented, and even if it overturns, the body is supported by the safety belt 110, and falling is prevented. The protective part 60 is arranged at the back of an operator, and even if the operator loses a balance backward, a protective fence part supports the body of the operator, and prevents a fall. Since a scaffold of the aerial scaffold 70 facilitates the center of gravity of the operator, a work range is expanded. Respective housing parts such as the shears housing part 80 are arranged in the ladder part 20, and a tool is easily take out at work time, and safety at fall time by nonpossession of the tool is secured.

摘要： PURPOSE:To prevent a measuring error, by a method wherein the rotary number of an engine when the current of a battery charging system is converted to positive from negative mode and the rotary number thereof when the current is contrarily converted to negative from positive mode are calculated and the average value of these rotary numbers is employed as measuring data. CONSTITUTION:When the rotary number of an engine 1 is gradually raised, the current of an electric line 5 connected to a battery 4 is converted to a positive (charging) state from a negative (discharge) state. The converted state is carried out by detecting a current value + or -0 by a current converting and measuring means 7 through a probe 6 connected to the electric line 5. The rotary number is measured by a rotary number measuring means 8 on the basis of said detection and stored in memory 10 by a measured data gathering and recording means 9. A state wherein the rotary number of the engine 1 is gradually lowered and a current is converted to the negative state from the positive state is detected by a current converting and measuring means 7 to measure the rotary number thereof and the average value of both rotary numbers are calculated by an average value calculating means 12 through the gathering and recording means 9 to be displayed by a display means 13. By this method, error measuring in the case of the abrupt change in the rotary number of the engine can be prevented.
