Title: Electronic blackboard
Inventor: SEGAWA MASAHIKO
IPC: H04N1/00
Filed: 1995-01-13
Abstract: PURPOSE: To prevent rattling noises on a rear face board of an electronic blackboard to be generated following the rolling action of a sheet. CONSTITUTION: A writing surface 5 is formed by exposing a sheet 3 out of an opening 4 on the front side of a frame 2, and an information written on the writing surface 5 of the rolling sheet 3 is read and output. At the time of rolling the sheet 3, although vibration is generated on an electronic blackboard, the vibration generated on the electronic blackboard is hard to be transmitted to a rear face board 15 through an air layer 14 by forming the air layer 14 inside the rear face board 15 blocking an opening 13 on the rear face side of the frame 2 to prevent rattling noises on the rear face board 15.

Abstract: PURPOSE:To make the constitution thin and improve the reliability by bringing a rigid body part into contact with a stopper part near a forwarding correction lever member when this member is turned by a certain quantity through a driving spring part of a forwarding correction transmission lever member by rotation of an operation shaft in one position. CONSTITUTION:When a crown 1 is pulled by one stage and is set to a position 1b and the crown 1 is rotated in the direction of an arrow R to rotate clockwise a clutch wheel 3, a cam 3a for forwarding correction is engaged with an engaging pin 13a to turn a forwarding correction transmission lever 13 in the direction of an arrow D, and a fowarding correction lever 15 is turned in the direction of an arrow E. As the result, a pawl of the lever 15 is engaged with a tooth of a date wheel 5, and the date wheel 5 is turned in the direction of an arrow F by one tooth for every turning operation of the lever 15 to forward a calendar, and the lever 15 is brought into contact with a stopper pin 17. When the crown 1 is turned in the direction of an arrow L, levers 13 and 15 are turned in directions opposite to directions of arrows D and E not to drive the date wheel 5 for correction, and the lever 15 is brought into contact with the pin 15. Thus, variance of machining accuracy is resolved by contacting.

Title: Semiconductor element and its manufacture
Inventor: HATA TOSHIO
IPC: H01L33/44
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To avoid introducing crystal defects into a semiconductor layer below a selective growing mask, by constituting the selective growing mask from a separate structure disposed near a substrate. SOLUTION: A selective growing mask 150 is laid on an n-type GaN contact layer 103 surface formed on a wafer 100 with the n-type GaN contact layer 103 so as to possibly approach to the wafer 100. With the selective growing mask 150 laid on the wafer 100, an n-type GaN layer 104 and n-type Al0.1 Ga0.9 N layer 105 of 0.3 μm are grown at a wafer temp. of 1050 deg.C. Because of the selective growing mask 150 not closely contacted to the n-type GaN layer 104, it is possible to avoid introducing crystal defects into the n-type GaN layer 104 surface even due to the thermal hysteresis in the selective growth step.

Title: Maintenance work device for elevator
Inventor: HIGASHIDE SHINICHI
IPC: B66B5/00
Filed: 1990-01-16
Abstract: PURPOSE:To make maintenance service personnel easy to transfer to both the upper and inner parts of a cage by installing a means which lights each pilot lamp in the top and inside of the cage when the cage floor and the top face are accorded with a hall floor. CONSTITUTION:When two service men transfer to the inside of a cage C and arrive at the third floor, by way of example, one person gets down to a hall 3H, and another service man in the cage pushes a descending maintenance operating button DB1 so that the cage is descended at low speed. When a top face of the cage C and a hall floor 3H are accorded with each other, a pilot lamp L2 in the cage is lighted, and when unhanding the button DB1, the cage C is stopped. Therefore the service man in the hall 3H opens a door of this hall 3H and is able to transfer onto the cage C so easily. When the service man on the cage C gets into the cage C, he transfers to the hall 3H, and an ascending operation button UB1 is pushed by another service man in the cage C so that the cage C is lifted up. When a cage floor accords with the hall floor 3H, the pilot lamp L1 is lighted and the button UB1 is unhanded, whereby the cage C comes to a stop, thus the service man can get into the cage C easily.

Title: Scattered ray removing and correcting method for scintillation camera
Inventor: OGUSHI AKIRA
IPC: G01T1/164
Filed: 1990-01-16
Abstract: PURPOSE:To facilitate data processing and to shorten the processing time by sectioning the crest value of the output signal of the scintillation camera into two areas and gathering data, and making scattered ray removal corrections at respective points of an image. CONSTITUTION:The output signal 4 of a gamma-ray detection part 3 is sent to a position calculating circuit 5 to calculate the XY coordinates of a gamma- ray incidence position. Two energy windows are set for the data gathering and the smoothing processes (F1 and F2) are performed by convolution arithmetic in this case. Then N1 and N2 which are found previously by the smoothing processes are used to calculate g11 and A1 and the g11A1N1 and N1 are used to calculate g11A1. In this case, statistical variation in g11A1 is controlled with only the N1 since the statistical variation of the N1 and N2 is small, so an increase in error is suppressed.

Filed: 1986-01-13
Abstract: PURPOSE:To make the depth of field confirmed at a preview time correspond to the depth of a finished picture and to remove the misconfirmation of the depth by opening a diaphragm largely if a trimming photographing mode is selected when a preview operating means for confirming the depth of field is operated at a trimming photographing time. CONSTITUTION:When trimming size in an equivalent stop value calculating routine is half size, a value obtained by stopping down practically calculated stop value Av by one level is set up as the equivalent stop value, and in case of quarter size, a value obtained by stopping down the step value Av by two levels is set up as the equivalent stop value. When the trimming size is half size, the practical stop value Av is opened by one level, and in case of quarter size, the value Av is opened by two levels. Since the depth of a picture obtained by trimming photographing becomes thinner that of a picture obtained by the normal photographing mode even if the same stop value is used, the stop value at the preview time is opened by a prescribed level by a preview button 4 so that the confirmed depth coincides with the depth of a finished picture.
