Title: Laser range finder, and its optical axis adjusting method
Inventor: MAEDA KOZO
IPC: G02B7/00
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a laser range finder capable of aligning easily an optical axis, and to provide an optical axis adjusting method using it. SOLUTION: A laser beam S1 from a laser projecting element 11 irradiates a laser range finder 20 when a measuring object 1 is absent, and it is reflected by a half-mirror 22 as a beam t2 to get incident into an optical axis monitoring light receiving element 24. The light receiving element 24 is also a one- dimensional optical sensor, and a light-incident position in its longitudinal direction can be detected. An imaging point of the beam t2 on a light receiving element 23 is in its central part when optical axes of one-dimensional laser range finders 10, 20 arranged to be face each other are consistent. But, when the axes are shifted, an imaging point of the beam t2 on the optical axis monitoring light receiving element 24 is shifted from the central part, and an electric signal output of the light receiving element 24 is also varied.  Since shifting amounts and directions of the optical axes are determined by variation of the signal output, correction for the optical axes is easily carried out.

Title: Sheet conveying device
Inventor: OBANA SHIGENORI
IPC: G03G15/00
Filed: 1991-06-06
Abstract: PURPOSE:To perform reliable conveyance even when sheets are of a kind incapable of being detected by a detecting means by operating a feed means through control of a control means even when clear sheets, such as OHP sheets, incapable of being detected by the detecting means are not detected by the detecting means during containing of the sheets in a containing means. CONSTITUTION:After a device body to contain OHP sheets is set in a sheet feed cassette, a sheet feed selection key and a copying mode selection key for a special sheet, located on a control panel 31, are turned ON.

Filed: 1989-05-29
Abstract: PURPOSE:To obtain the data of the heat change of a sample by measuring the temperature of a sample, and obtaining the difference between the measured temperature and a preset temperature at each time point of the temperature increase and decrease. CONSTITUTION:The temperature increasing curve of a program temperature control device 4 is set as shown in a straight line A. The temperature of a heating furnace 1 is increased in accordance with the temperature increasing curve. Thus, the temperature of a sample to be measured 3 contained in a sample container 2 is increased along a temperature increasing curve shown in a curve B. At this time, when endothermic change occurs at a time t1 in the sample 3, a small peak curve Pa is formed at a part between the time t1 and the time t2. Since the straight line A is the program-set temperature curve, the temperature of the heating furnace is controlled as shown by the straight line A. Then, the environment temperature wherein the sample 3 is mounted increases as shown by the straight line A. When the difference between the straight line B and the straight line A is obtained, the same heat change data as in the case in a DTA method can be obtained.
