Second lugs 26, 28 having inclining faces are formed within the interval of the lugs 16, 18, i.e., on the inside of the projecting parts 6, 8. When a fixing screw 20 is driven, a tightening force of the fixing screw and a nut 40 acts between the projecting parts 6, 8 to bring the lugs 26, 28 having inclining faces into contact. When the fixing screw 20 is driven further, a slip takes place between the lugs 26, 28. Tightening force of the fixing screw 20 is converted through abrasion caused by the slip between the lugs 26, 28 into fastening force of a band body 4.

Title: Image reader
Inventor: MURAZAKI MAKOTO
IPC: H04N1/04
Filed: 1991-12-24
Abstract: PURPOSE:To improve printing quality by stabilizing the reading ability of an image sensor regardless of an original size. CONSTITUTION:Although a paper feeding guide 41 is slid corresponding to the width of an original 42 when the original 42 is set, the original width is converted to a voltage by a slide volume 43 to be operated synchronously with this slide amount, and this voltage is converted to a pulse by a voltage/pulse conversion circuit 45 so as to detect the original size. A control pulse generation circuit 46 generates a control pulse showing the reading range of an original base output corresponding to the original size and further, a slice level is set by letting this original base output follow up a reference voltage. Moreover, since analog data from the image sensor to read the original 42 are converted to binary data and read with this slice level as a reference, the original size is exactly detected regardless of the size of the original, and the optimum slice level is set.

Title: Hot-water space heater
Inventor: TOMITA AKIO
IPC: F24D3/00
Filed: 1991-11-28
Abstract: PURPOSE:To improve thermal efficiency by a method wherein the flow rate of a heat medium is choked automatically to reduce a returning temperature when the returning temperature from a boiler is increased. CONSTITUTION:The outputs of thermistors 6, 7, which detect heat medium temperature in a sending pipeline 2 and a returning pipeline 3, are sent to a controller 8 and are compared with a reference voltage corresponding to respective set temperatures whereby the fuel supplying proportional valve 9 and the number of rotation of a pump are controlled so as to be constant. Accordingly, when a space heating load is reduced and a returning temperature is begun to increase, for example, the voltage of the thermistor 7 is increased and the number of rotation of the pump 4 is reduced whereby the flow rate of heat medium is reduced and the returning temperature is maintained in constant. As a result, the thermal output of a condensing boiler 1 is reduced and a temperature in a heat exchanger 12 is increased, however, the thermistor 6 detects it and the fuel supplying amount of a gas burner 11 is kept in constant whereby the thermal efficiency of the boiler 1 is improved.
