Abstract: PURPOSE:To prevent the clogging in a transfer chute and detect the fully charged state of a holding container. CONSTITUTION:A transmission-type photo-sensor 17 is placed at the outlet of a chute for the transfer of a transfer object and the passing density of mowed grass is detected near the outlet by the output signal of the sensor. An H level counter 21 counts the H level signals of the photo-sensor 17 outputted from a level detector 20 at prescribed time intervals. The average light-shielding ratio of the H level signal during plural sampling periods is calculated by a passing density judging value calculation part 22. The calculation of the average light-shielding ratio is carried out after the completion of each sampling period in response with the sampling period end signal transmitted from a counter 23. When the average value exceeds a threshold value, a clogging state judging part 24 commands the clogging alarming part 28 to send an alarm. The duration time of the clogged state is counted by a clogging counter 29 and a full-state information command is outputted to a full state alarming part 30 when the clogged state continues over a prescribed period.

Title: Mos amplifying circuit
Inventor: TAKAHASHI KAZUKIYO
IPC: H03K5/02
Filed: 1981-04-09
Abstract: PURPOSE: To reduce as less as possible the electric power that is reduced in the queuing mode, by controlling the queuing time with use of two switches.  
     CONSTITUTION: The 1st power supply applies the positive DC voltage to an MOSFET21 corresponding to a load element through a power supply line 20; and the 2nd power supply applies the zero value to the source electrode of an MOSFET23. In such constitution of circuit, the MOSFETs 23 and 24 are turned off and on respectively since control signals ψ 1  and ψ 2  are set at a high and low level respectively in the regionI. And the circuit is in the queuing mode, and as a result no electric power is consumed. The signals ψ 1  and ψ 2  are set at a high level each in the region II, and the circuit is still in the queuing mode. Thus the working point is decided for an inverter circuit consisting of the FETs21 and 24. The voltage is charged to a coupling capacity 3. The signals ψ 1  and ψ 2  are set at a low and high level respectively in the region III to put the circuit in an active mode. The time of the region II can be substantially equal to the charging time of the capacity 3 to be shorter than the time of the region I. As a result, the power consumption in the queuing mode equivalent to the sum of the time durations of the regionsIand II can be reduced.

IPC: B60H1/08
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To enhance cooling capacity in a valveless type air conditioner for a vehicle at a low cost. SOLUTION: Since a heat exchanger 12 is so disposed at to allow draft to be led upward from down below, and an air mixing chamber part 19 is disposed to the right side of a vehicle (cooling air passage H side) of the heat exchanger 12, radiation heat (hot air) from the heat exchanger 12 is moved directing to the wall 15a of a hot air passage 15 as indicated by an arrow head M. And the hot air passage 15 is curved toward down below, that is, since the wall part 15a (inner wall part) is in a projected shape projecting upward, hot air moved upward is held up in this portion 55 (hold-up part). Thus, since no hot air from the heat exchanger 12 comes in the inside of the air mixing chamber part 19, cooling capacity can be inexpensively enhanced devicing the layout of the air conditioner in a valveless type air conditioner.
