IPC: F25C1/00
Filed: 1990-03-12
Abstract: PURPOSE:To make substantially normal ice even when a sensor is in an abnormal condition, by using a microcomputer so that an ice-making time and a period of time required for ice separation can be stored through updating upon each run of ice-making operation, and continuing the operation by use of the time data thus stored. CONSTITUTION:Pre-cooling time required for a pre-cooling step is measured by a timer-1, and the pre-cooling time data is stored in a memory-1. Ice-making time is measured by a timer-2, and the time data is stored in a memory-2. Ice separation time required for an ice-separating step is measured by a timer-3, and the time data is stored in a memory-3. The stored data is updated also when the ambient temperature varies and the times counted by the timer-1, timer-2 and timer-3 are varied. By utilizing the time data, an ice-making operation can be carried out even when a cooler sensor 32 or a condenser sensor 33 is in an abnormal condition. A microcomputer 35 controls the ice-making and ice-separating steps, based on outputs from the two sensors.

Title: Continuous sheet conveying device for recorder
Inventor: SHIKATO MASANOBU
IPC: B41J15/16
Filed: 1981-04-17
Abstract: PURPOSE:To prevent lack of a picture at a picture fixing part at a time when a continuous sheet starts and stops, by forming a slack on the continuous sheet between a picture recording part and a picture fixing part in a recorder. CONSTITUTION:When conducting an initial setting of a fan fold paper 1, the crease position of the paper 1 first matches a transfer part 20, and the paper 1 is set at tractors 3, 4, and 10. The paper 1 is then fed by a given distance, and a forward end 22 thereof is inserted into a stacker. After the paper is further fed by a given distance, with only a motor 5 run, the paper is fed, and this allow a slack to form between guide rollers 9 and 10. The paper is then set such that the passage of a paper from the transfer part 20 to an electrodeposition part 21 is an integral number of times as long as a page length, and a crease is positioned facing and opposite to a fixing part 21 as well. If the paper is caused to start and stop hereafter only at a time when the crease comes to the transfer part 20, even if a pressurizing roller 15 is released at the electrodeposition part 20, the paper starts from and stops at a crease position, and this eliminates a fear of lack of picture.

The first comparator 11 judges that a human body is in a quiet state when the output from the integrator 10 is within a definite range to issue output and, in a sleeping judging means 12, a timer performs clocking operation when there is output from the first comparator 11 and the clocking operation of the timer 13 is stopped when there is no output and the timer 13 is reset and the second comparator 14 judges that the human body is in a sleeping state when the time (t) clocked by the timer 13 reaches a predetermined time to or more. Therefore, it is unnecessary to perform complicated and expensive signal processing and a sleeping state can be judged in low cost in a practical form.

Title: Inspection instrument

IPC: H01L21/66
Filed: 1987-03-16
Abstract: PURPOSE:To detect the inclination at the edge portion of a pattern formed on the surface of an object to be inspected by comparing a reference signal waveform and a signal waveform indicative of change in the intensity of reflected light or scattered light from the object to be inspected. CONSTITUTION:A memory 10 is provided for holding a variety of signal waveforms 6 (6a, 6b) changing in accordance with an inclination between the edge portion of a photoresist pattern 2 and the ground portion of a semiconductor wafer 1 as reference waveforms 11 together with corresponding inclinations. A variety of the waveforms 6a and the like from the pattern 2 are compared with the waveforms 11 with each other to determine the inclination of the edge portion of the pattern 2. Thus, it is avoided that, for example, width dimensions are measured only on the pattern 2 having the edge portion with the inclination within a prescribed range and an inspection is conducted in a condition wherein an accuracy in detecting the inclination of the edge portion is low by being affected by the flattening of the waveforms 6 due to the decrease in the inclination of the edge portion. Therefore, an accuracy in measuring the width dimensions of the pattern 2 on the basis of the distance of the edge portion is improved.
