Title: Demisting control device
Inventor: TAKEMASA MASAMI
IPC: B60H1/32
Filed: 1986-07-24
Abstract: PURPOSE:To carry out a demisting process properly depending upon the extent of mist on the internal surface of window glass by controlling demiting capacity for increase or decrease on the basis of the time change of humidity on said surface, and interrupting the reduction control when a control object has agreed to a condition before the start of demisting. CONSTITUTION:Humidity on the internal surface of window glass is detected with a detecting means 'A' and a discrimination means 'B' makes judgement as to whether demisting is necessary or unnecessary on the basis of the detected humidity. Also, when demisting is necessary, a memory means 'C' takes in humidity every predetermined time and temporarily stores the humidity. And each of control means 'E' and 'F' controls an airconditioning system '0' so that demising capacity will increase or decrease, and a select means ''0.' selects either of said means 'E' and 'F' on the basis of the stored humidity. On the other hand, the condition of a control object before the start of demisting is temporarily saved in a memory means 'N' and when the control object has agreed to the condition before the start of demisting in demisting capacity reduction control, an interrupt means 'I' stops the reduction control.

Abstract: PROBLEM TO BE SOLVED: To operate an operation lever smoothly and prevent the abnormal wear of a contact part by interposing a disk-shaped press spring between the operation lever and a return spring and energizing a camshaft in the bottom direction of a cam shaft hole. SOLUTION: A dish-shaped press spring 20 is interposed between the end part 13c of a return spring 13 and an operation lever 12 and energizes a cam shaft 11 in the bottom direction of a camhaft hole 2e.
