Title: Pelletizing device of semiconductor wafer
Inventor: SAKAI EIJI
IPC: H01L21/78
Filed: 1987-06-24
Abstract: PURPOSE:To make it possible to favorably and efficiently cut off and separate a semiconductor wafer by a method wherein a driving source is controlled by the detection signal of a strain sensor, which detects the stress applied to a cutter during the cutting-off and separation of the semiconductor wafer with the cutter. CONSTITUTION:A strain gage 14, which acts as a sensor and to which an electric signal converting part 15 is connected, is fixed by bonding to the thin part 9 of a holder 8. When the stress applied through a cutter 11 to the holder 8 by bringing the cutter 11 into contact with a semiconductor wafer 18 exceeds a certain level, the lowered position of the cutter 11 at that time is recognized through the electric signal converting part 15 by a drive controlling part 16. That is, the position, at which the predetermined stress develops in the holder 8, is regarded as the contact position of the cutter with the semiconductor wafer 18 and, as a result, at said contact position, floating of the semiconductor wafer 18 in contact position on a table 17 is eliminated. When the contact position of the cutter 11 with the semiconductor wafer 18 is detected, the holder 8 or the cutter 11 is driven downwards in Z-axis direction so as to cut off and separate the semiconductor wafer 18.

Title: Picture processor
Inventor: OKINO YOSHIHARU
IPC: G06V10/20
Filed: 1982-09-11
Abstract: PURPOSE:To decide a region with high precision through a simple circuit constitution for a picture processor which quantizes a picture signal, by adding the result of decision, feature quantity of each block region to the decision region of subsequent row. CONSTITUTION:Each block region is decided by defining a block of N picture elements and X1 rows of an input signal 301 obtained by giving a raster scan to an original picture. The result of this decision and the feature quantity of the block are stored in a region information memory 304 and then used for decision of subsequent blocks. Therefore the region information equivalent to just a block can be stored in a picture memory 305. This reduces the memory capacity. Furthermore an error is reduced for the decision of the region since the region information of a small number of block preceding a relevant block is stored to be used for the decision of the subsequent region.

Title: Motor controller for power steering gear
Inventor: NAGAI SADASHI
IPC: B62D6/00
Filed: 1982-09-10
Abstract: PURPOSE:To prevent an assisting force from becoming excessively large even at the time of a rapid braking during high-speed running, by controlling a supply power quantity regulating means by a signal from a rapid braking detecting means so that the quantity of electric power supplied to a motor is forcibly reduced to or below a predetermined value. CONSTITUTION:When rapid braking is conducted during high-speed running, signals from a vehicle speed sensor 21 and a brake switch 26 are inputted into an AND circuit 51 provided in a rapid braking detecting circuit 24. Since the circuit 51 causes the output from a Q'-terminal of a flip-flop 50 to become ''L'', an output from an AND circuit A remains to be ''L'' even when a signal from a steering sensor 36 is inputted. The output ''L'' from the circuit A is inverted into ''H'', and is inputted into an AND circuit 37. The circuit 37 supplies a signal PI from an idle signal generating circuit 38 to a power transistor 30 provided in the supply power quantity regulator 19. In accordance with the signal, the transistor 30 supplies a small amount of an electric current I to the motor 18, and the motor 18 is operated in an idling condition. Accordingly, discharge quantity of a pump is restricted, and the assisting force at the time of rapid braking is maintained to be appropriate.
