Title: Impurity diffusion of semiconductor layer
Inventor: TSUCHIYA KAZUHIRO
IPC: H01L21/329
Filed: 1988-08-18
Abstract: PURPOSE:To reduce the number of times of thermal diffusion, which is equal to the number of semiconductor layers with different impurity concentrations and different depths, even in the case of layers of the same, conductivity type, required by the conventional method, to just one heating process by utilizing the difference in the velocities of impurity diffusion in an amorphous semiconductor and a crystalline semiconductor. CONSTITUTION:An n-type semiconductor region 3a is separated from an epitaxial layer 3 by separation layers 4 and an oxide film 50 is removed from a range where a graft base layer of the above semiconductor region 3a is to be formed. A resist film 60 is provided and a ring pattern window for an outside base layer is opened and, for example, silicon ions are implanted to form an amorphous layer 10a having a depth of 1-2mm. The resist film 60 is applied again and a window for an inside base layer is opened. For example, boron ions are implanted and an impurity injecting layer 20a is formed so that a part of its layer is put on top of the layer 10a at a depth of about 0.5mum. Then, impurities are diffused completely in the layer 10a at a temperature of about 600 deg.C and when the temperature is raised up to 1100 deg.C, the impurities are diffused to peripheral parts of layers 10a and 20a. A p-type graft base layer 8 is formed in the semiconductor region 3a in such a way that the first semiconductor layer 10 where its diffusion is deep and an impurity concentration is low is formed as the outside base layer, thus, the second semiconductor layer 20 where its diffusion is shallow and the impurity concentration is high is formed as the inside base layer.

Title: Finger pinch preventing fitting for concrete bucket
Inventor: KAMAHARA KAZUTOMI
IPC: E04G21/02
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To increase safety by installing a ring-shaped or a channel-shaped fitting surrounding a whole lifting ring when a lifting fitting is attached tiltably through a pivot pin to the lifting ring fixed to the upper side of a concrete bucket main body. SOLUTION: A ring-shaped or a channel-shaped finger pinch preventing fitting 6 is fitted closely on the outside of a lifting eye 5 of a concrete bucket main body 1. Next, when a lifting fitting 2 is tilted, a tilted angle is limited because the fitting 2 is brought in contact with the fitting 6. Thus, as long as fingers are present on the upper peripheral surface of the bucket main body, finger pinch between the lifting fitting 2 and the bucket main body can be prevented.

Filed: 1986-09-02
Abstract: PURPOSE:To obtain an absolute rotary encoder of simple constitution by providing a disk, a linear image sensor etc. CONSTITUTION:The disk is a certain angle position and light beams are incident on plural elements of the linear image sensor 3. The incidence position moves on the elements according to the rotation of the disk. Then, a readout clock CK is impressed to the sensor 3 through a gate 10. A counter 5 which forms the 1st counter is set synchronously with it. Further, the output of the sensor 3 is impressed to a comparator 4. When the comparator 4 generates its output, a counter 5 is stopped from counting with the output and a counter 8 is started at the same time. The counter 5 is stopped after counting the number A of clocks until the output of the comparator 4 is generated. This counter 8 and a 1/2 frequency divider 7 form the 2nd counter and the outputs of the counters 8 and 5 are added 6 together. Thus, the center position where the spot strikes is calculated to read the absolute position of the rotary body.
