Title: Semiconductor radiation detector
Inventor: HIRANO RYUMA
IPC: G01T3/08
Filed: 1988-09-26
Abstract: PURPOSE:To obtain a semiconductor radiation detector which improves the detection sensitivity of neutron with low operating voltage and lessens aged changes and is superior in characteristics of a resistance to environment by providing a coating containing boron on a single crystal semiconductor substrate and at a part of the region on an amorphous semiconductor layer which forms heterojunction. CONSTITUTION:A coating 3 containing at least boron is provided on a single crystal semiconductor substrate 1 and at least at a part of the region on an amorphous semiconductor layer 2 which forms heterojunction and then, metallic electrodes 4 and 5 which cover the coating are mounted on the coating. As it is possible to cause the amorphous semiconductor layer 2 to have the film thickness of 200 nm or less, it is sufficiently thin as an insensitive layer to alpha rays. As there is a structure where the boron coating 3 and a heterojunction interface are formed across the above layer 2, the alpha rays may arrive at a depletion layer efficiently. Further, in this structure, as there is the boron coating 3 that is the generation source of the alpha rays by neutrons in the vicinity of the depletion layer even under inverse biased voltage, this configuration does not worsen the sensitivity of its detector. The covering of boron coating 3 with the metallic electrodes 4 and 5 protects the coating from contact with the outside air.

Title: Vibrating sifter
Inventor: SUEHIRO ATSUO
IPC: B07B1/28
Filed: 1988-09-26
Abstract: PURPOSE:To improve sifting efficiency by equipping both an operation controlling device for changing vibrating acceleration and an opening and closing device for opening and closing the discharge port on a mesh. CONSTITUTION:When a raw material is introduced on a screening mesh 11 from an introduction port 27 and sifting operation is started, a motor 3 is driven at 1800r.p.m. by an operation controlling device 25. Thereby vibrating acceleration imparted to both screening meshes 11, 12 is regulated to about 5G and this state is held for one minute. Thereafter the number of revolutions of the motor 3 is reduced to 900r.p.m. and vibrating acceleration is reduced to about 2.5G and this state is held for one minute. Both a state large in vibrating acceleration and a state small therein are caused during sifting operation and when vibrating acceleration is made large, the raw material on the screening meshes 11, 12 is beaten and therefore separation of small particles and fine powder stuck on large particles is promoted. Thereby sifting efficiency can be improved.

Then an output of the feedback circuit 11 is fed to an input signal 1(IN) by an adder 3. Moreover, a re-quantization error Vq is added to an input signal 10(QIN) of a local quantizer 7 at the local quantizer 7 to obtain an output signal 13. Thus, the output signal 13(OUT2) is expressed in equation III, and the entire characteristic is a tertiary noise shaping characteristic divided by a term of (1-5Z<-1>+0.5<-2>). Thus, the gradation in the entire output is reduced.

Title: Production of laminated board with adhesives for additive method printed wiring board
Inventor: KATO HIDEO
IPC: H05K3/18
Filed: 1992-09-10
Abstract: PURPOSE:To improve the surface flatness of laminated board with adhesive agent and its heat resistance by applying thinner electroless plating than specified on one side or both sides of the laminated board, repeating same process, e.g. applying an active adhesives and heating it, and forming an adhesives layer having a specified thickness. CONSTITUTION:After one side or both sides of a laminated board is applied with electroless plating thinner than specified, an active adhesive agent is coated/heated thereon and the same process is repeated to form a adhesives layer of a specified thickness. In this case, it is preferrable to repeat two or three times, so the coating thickness per time is recommended to be one third to one half of the specified thickness. In addition, a first coating adhesive agent is added with a slightly large amount of diluted solvent in order to decrease the viscosity thereof and improve the wettability against the laminated board, therefore it becomes hard to generate any failures such as thinning of coating thickness. A heating temperature after coating is set at around boiling temperature of the diluted solvent enough to remove the volatile components such as solvent in the adhesives. Thus, the surface failures can be eliminated so as to improve the surface flatness.

Filed: 1992-08-17
Abstract: PURPOSE:To enable switching to either of redundancy or parallelism at a test which is considered as advantageous to be conducted in a manufacturing process after wafer process or in a process of the latter half by cutting fuses. CONSTITUTION:When second fuses 12a-12n are all cut leaving first fuses 11a-11n as they are, since the fuses 11a-11n become effective and a SEND signal is sent to block selecting signal generation circuits BS of each section, redundancy can be realized in a section independently of blocks. Also, in a test mode in which parallel reading is performed, only one section is made disable, and the other sections can be used by checking an output from OR gates 15a-15n at the time of a test mode. On the other hand, when the fuses 11a-11n are cut leaving the fuses 12a-12n as they are, redundant cells can be used in all blocks, but test output from each section can not be obtained, and the test mode can not be used.
