Title: Inspecting method for packaging component
Inventor: KAKIGI GIICHI
IPC: G01B11/24
Filed: 1986-05-20
Abstract: PURPOSE:To accurately detect a component and decide its position even on a curved printed board by measuring the curvature state of the printed board previously and moving a line sensor and light beams. CONSTITUTION:The heights of both end parts of an area on the printed board P are measured by using displacement (height) sensors 19 and 20 to measure the curvature state of the board P. Then, slit beams l are generated by a beam unit 10 to illuminate the board P. The unit 10 is fixed on a rotary stage 15 and rotated according to the tilt angle of the board P and the beams l are therefore rotated by the same angle. The beams l on the board P, on the other hand, are passed through an image forming lens 16 in the opposite direction from the incidence direction to form an image on a line sensor 17. The sensor 17 detects only the position of specific height on the board P by the principle of a light cutting method. The sensor 17 is fixed on a stage 18 and moved in parallel from a reference position by distance (d) along an image formation surface according to the curvature quantity (height) of the board P. The sensor 17 detects different heights on the board P by said movement.

Title: Optical system driver
Inventor: IKARI ICHIRO
IPC: G11B7/09
Filed: 1990-05-01
Abstract: PURPOSE:To keep high driving sensitivity and to stably perform servo by eliminating a part being superimposed on a coil at a partition between a yoke inside a holding member and a magnet. CONSTITUTION:The upper and lower parts of a focusing coil 9 are sandwiched between an upper perpendicular rib 7b and a lower perpendicular rib 7c in a magnetic gap. In such a case, the part being superimposed on the focusing coil 9 at the partition between the inner yoke 3 of a lens holding member 7 and a permanent magnet 4 is eliminated. Thereby, since a gap part exists between the upper perpendicular rib 7b and the lower perpendicular rib 7c, the gap between the permanent magnet 4 and the inner yoke 3 can be minimized, and as a result, flux density functioning on the coil can be increased, and the driving sensitivity can be heightened, then, the objective lens can stably follow the information track of a disk.

Abstract: PURPOSE: To improve the mobility of electrons in the channel layer to be formed by the growth of crystal on a semiconductor layer. CONSTITUTION: After a buffer layer 11, an undoped layer 12 and a semiconductor layer 13 have been successively grown on a GaAs semiconductor substrate 10, an impurity-undoped GaAs channel layer 14 is crystal-grown on the semiconductor layer 13. As the electrons of two-dimensional electron gas are migrate to the opposite side of crystal growth direction and diffused into the semiconductor layer 13 because crystal is grown while electric field is being applied to crystal growth direction, the migration of electrons to the channel layer 14 is lessened, and a defect is not formed on the channel layer 14. Then, after an impurity-doped GaAs cap layer 15 has been formed on the channel layer 14, the cap layer 15 is recess-etched, and a gate electrode 16, a source electrode 17 and a drain electrode 18 are formed.

Title: Expansion tank for cooling water supply device
Inventor: KAWAMOTO TSUKASA
IPC: F25D17/02
Filed: 1989-05-09
Abstract: PURPOSE:To prevent the intrusion of foreign substances into the cooling water and the corrosion of pipes and also to reduce inconveniences of replenishing the cooling water by employing a sealed structure where a part of the side wall of the expansion tank consists of a flexible membrane. CONSTITUTION:When the pressure builds up in the cooling water circulation line 44, a corresponding quantity of cooling water flows into the main tank 71 through a bypass pipe 41 and raise the water level therein. As the air in the main tank 71, in turn, flows into the expansion tank 73 to push down the membrane 73a to increase the tank volume, the pressure build-up is absorbed to balance out the internal pressure of the tank nearly at the atmospheric pressure so as to maintain the atmospheric pressure at the cooling water outlet of a heat exchanger 2. On the other hand, when the pressure drops in the cooling water circulation line 4, the membrane 73a in the expansion tank 7 deforms to reduce the tank volume so as to absorb the pressure fluctuation. The interior space of the expansion tank 7 is sealed off from the atmosphere. By this constitution, the intrusion of foreign substances into the cooling water and the corrosion of pipes can be prevented and inconveniences of frequent replenishment of the cooling water can be solved.

Title: Counter circuit having self-checking function
Inventor: TAKAGI HARUO
IPC: G06F11/00
Filed: 1983-06-29
Abstract: PURPOSE:To facilitate the checking of a counter circuit by comparing the result of addition with the count value obtained after a step through a comparator for each step. CONSTITUTION:A counter 1 contains plural FFs and synchronizes with the clock CK. The numerical value is added to the count value Q of the counter 1 by a half adder 2, and the output value of the adder 2 is stored in a register 3. The register 3 is synchronous with the CK, and the output value is supplied to a comparator 4 at the step of the next stage. The count value of the counter 1 obtained at the same step as that where the output value is supplied to the comparator 4 is also supplied to the comparator 4 at the same step. The value obtained by adding 1 to the count value of the counter 1 is equal to the expected value of the count value at the next step. Thus an error of a counter circuit is checked by comparing both input values with each other by the comparator 4.

Title: Character recognition system
Inventor: UEDA SHUNICHI
IPC: G06K9/00
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To effectively recognize the characters which are printed on a voucher without preparing plural dictionaries by adding a reference character print means to an output device and also adding a dictionary production means and a recognition means to a processor. SOLUTION: An OCR 10 used in a voucher processing system does not recognize the characters by means of plural dictionaries which are previously registered but produces an exclusive dictionary for a voucher 17 and recognizes the characters based on this dictionary. That is, the OCR 10 segments she image of every character out of the reference area of the voucher 17 and produces a dictionary in response to the voucher 17 to recognize the types of characters of the voucher 17 by means of this dictionary. Therefore, when the voucher 17 is printed at a WS(work station) 16a of an order receiver by a printer 16b, the reference characters are previously printed in sequence in the reference area of the voucher 17 in a prescribed order. In other words, the printer 16b has a function to print the reference characters in the reference area in a prescribed sequence. Then the character types can be specified based on only the position of every character image included in the reference area.

Abstract: PURPOSE: To prevent a sound reproduced by a sound equipment from leaking out. CONSTITUTION: A sound signal is amplified by an output amplifier 1, and is transduced a sound wave by a speaker 2, and in such a manner, music is reproduced. Simultaneously, the sound signal is phase inverted by a phase inversion circuit 3, and is amplified by the output amplifiers 5a-5c to be converted to the sound waves by the speakers 6a-6c. Since the sound wave from the speaker 2 is the phase opposite to the sound waves from the speakers 6a-6c, by that the synthesis of the sound waves are performed, the sound of the speaker 2 leaking out of a reproducing sound field 7 is canceled. Further, by performing the phase adjustment by delay circuits 4a-4c, the volume adjustment by the output amplifiers 5a-5c, the acoustic characteristic of the sound field 7 is set in freely.
