Title: Heating device
Inventor: KIHARA HITOSHI
IPC: F01L1/04
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To facilitate temperature control when a cam piece is to be heated. SOLUTION: A heating means 42 is inserted into an opening 26 in a cam piece 18, and a plurality of plates 43 deform uniformly to make contacting with the inside surface of the opening 26 uniformly over the whole circumference. Further, the plates 43 are put in pressure contact with the inner side face of the opening 26 by an elastic force generated by deformation of the plates 43. Even in the case the heating means 42 is inserted in the condition that its axis out of alignment from the center of the opening 26, the plates 43 deform appropriately along the inner side face of the opening 26 so that all of the plates 43 are in tight attachment to the inner side face. That is, the area of tight attachment to the inner side face is constant irrespective of the condition in which the heating means 42 is inserted in the opening 26, and the amount of heat conduction per unit time is stabilized at all times. Because the plates 43 are all heated to a temp. approx. the same as a plug heater 37, and it is possible to uniformly heat the inside circumferential surface of the opening 26 in a short time.

Filed: 1978-12-15
Abstract: PURPOSE:To reduce the high frequency component contained in the control voltage by obtaining the control voltage from the output frequency of the voltage control oscillator via the D/A converter circuit and the sample holding circuit. CONSTITUTION:Output frequency MNf0 of voltage control oscillator is divided through MN divider and then sent to D/A converter 12. The output voltage of converter 12 rises up in steps with every input of the output pulse of divider 11 and then reset in the fO cycle. This staircase waveform is sampled in the fr cycle to be applied to low band pass filter 9 after the voltage is held at holding circuit 14. The frequency component of the impulsive noise caused by the gate pulse of gate circuit 13 is extremely high, and the high frequency component contained in the output DC voltage of circuit 14 is small. As a result, the degree of designing freedom is increased for filter 9.

Abstract: PURPOSE:To eliminate dimensional layout conducted by a mental calculation and to directly allocate it at once by using 1/6, 1/5, 1/4 of one ken as units, and employing one or more types of the plurality of these dimensions as graduations. CONSTITUTION:In order to easily distinguish gradations when the graduations of a plurality of dimensions are marked on a ruler having no graduation, the methods of the following six ways are used.

The lengths of graduation lines are altered, and the lines for representing the same dimensions are gathered by lateral lines (3, 3'). The thicknesses of the lateral lines for gathering the graduations are altered (4). Marks are attached to the graduations (5). The graduations are divided by colors. When one reduced scale is, for example, divided into two, the one is of a shaku dimensional type and the other is of a meter type, in the case of the shaku dimensional type (the same as the meter type), the graduations of the same lengths of 1/6 (1'), 1/5 (2') and 1/4 (3') of units are connected by lateral lines and gathered.

Abstract: PURPOSE: To increase microorganism activity by cultivating soil microorganisms adequate to returned activated sludge and by supplying them to the returned activated sludge.  
     CONSTITUTION: When returned waste sludge is sent from return pipe 1 and supplied to the bottom of contact aeration tank 4 from the lower part of T-shaped pipe 9, waste water level WL 1  rises up to the designed maximum waste-water level WL 2 .
