Title: Position detector
Inventor: NARUSE MASAYUKI
IPC: G01B11/00
Filed: 1979-04-12
Abstract: PURPOSE:To prevent a wrong connection by a method wherein the central coordinate is detected from a binary figure obtained after photoelectric scanning by the pattern matching method, and the result obtained is compared with the previous connecting position. CONSTITUTION:The position of a pellet previously recognized and connected is 101, and the central position of the electrode of the pellet is B1, then coordinates X1, Y1 are memorized 7. The position of the pellet is 102, and coordinates X2, Y2 of the central position of the electrode are memorized 9. B3 indicates the central coordinate of another pellet. A specified range + or -a, + or -b in the direction of an axis of  coordinates from the position B1 previously recognized is provided beforehand, and  the connection is carried out when the coordinates are within the range, based on  the understanding that the electrode is normal, but, in case they are not within the  range, they are recognized again or transferred to the next pellet. After the connection is carried out on the basis of recognizing the normal electrode, the coordinates  are transferred from the register 9-7 in parallel, and they are treated as the central values within the specified range for the next pellet. By so doing, noise of the same figure as that of the electrode on the lead frame is recognized while preventing a wrong connection.

Abstract: PURPOSE: To efficiently finish this crown wheel by inclining a tool around the axis coincident with the axis of rotation of a cylindrical gear when the tool being a disk-shaped mechanical element makes reciprocating linear motion by meshing with the crown wheel, and specifying the ratio of inclining motion of the tool to rotational angular velocity of the crown wheel. CONSTITUTION: A metallic cutting tool 8 is arranged to a crown wheel 1 so that this tooth shape substantially coincides with a tooth shape of a cylindrical gear 2 when meshing with the crown wheel 1 to be made. This tool 8 is vertical to the axis 9 of rotation, makes reciprocating linear motion in the groove direction between teeth of the crown wheel 1, and is inclined around the single axis 6 coincident with the axis of rotation of the cylindrical gear 2. The ratio of inclining motion of this tool to rotational angular velocity of the crown wheel 1 coincides with the transmission ratio between the crown wheel 1 and the cylindrical gear 2. While the tool 8 is drawn back from the tooth surface of the crown wheel 1, the crown wheel 1 is rotated to machine the next tooth.

Title: Case of electronic component package
Inventor: KAWASAKI SETSUKO
IPC: H01L23/28
Filed: 1987-02-28
Abstract: PURPOSE:To deliver thermal stress due to temperature change to a case, and prevent cracks from generating in an electronic component package, by forming a slit so thin and long that filled resin does not flow out to a sidewall of the case. CONSTITUTION:The case 2 of an electronic components package 1 is provided with slits 3 at a side part of the case and especially at four corner parts. The slits are so thin that filled resin 4 of injection does not flow out. About a half of the case is filled with the resin 4, on which electronic components 5 are arranged. The resin 4 is again injected, and the electronic components 5 are completely buried and solidified. If the filled resin 4 in the case expands on account of temperature rise, the thermal deformation can be delivered to the case side by the effect of slits 3 in the case 2. Thereby, the cracks and characteristics change of electronic components caused by the thermal stress can be prevented.

Title: Rectification compensator of dc machine
Inventor: OHARAGI HARUO
IPC: H02P7/03
Filed: 1985-03-09
Abstract: PURPOSE:To always compensate a rectification by correcting a current flowed to an auxiliary winding in response to excess or insufficient value of a rectification compensating amount and the magnitude of the value. CONSTITUTION:The outputs of a current detector 13 and a rotating speed detector 14 are input to a multiplier 15, and the result is input to a gate signal generator 16. The switching frequency and the conduction rate of a current controller are controlled by the obtained gate signal to control a current flowed to an auxiliary winding 8. The position of a sparkless zone varies as the operating time is elapsed, and when exceeding a rectification compensating range, a spark is generated from a brush 11. The excess or insufficient value of the rectification compensating amount and the magnitude of the amount are detected by a search coil 19, and a rectification compensating amount correcting circuit 20 outputs a correcting voltage in response to the output of the coil 19. Thus, the optimum rectification compensation can be always performed.

IPC: G11C11/412
Filed: 1983-03-18
Abstract: PURPOSE:To improve an integrated degree and the power consumption of the semiconductor static memory cell by constituting the memory cell of a connecting transistor of the 1st conductivity type and a driving transistor of the 2nd conductivity type. CONSTITUTION:The riving transistors 1 and 2 are NMOSTs having a VT of 1V and connect a lower power source Vss 13 (=0 V) with node points 5 and 6. The connecting transistors 3 and 4 are PMOST having a VT of 0.2 V and connect data lines DL7 and -DL8 with contacts N1 and N2, respectively. The gate of the transistor 1 is connected with the node point 6 and the gate of the transistor 2 is connected with the node point 5. The gates of the transistors 3 and 4 are connected with an AL9. A dynamic loading circuit 13 is constituted of PMOSTs 10, 11, and 12. An electric current is conducted reversely through the data line DL7 during the accessing period of the reading out cycle. When the node point 5 is made to have an electric potential of about +4.5V during the non-accessing period by adjusting the leak current of the NMOST1 and PMOST3, reverse leak current obtains almost 0 (zero) during the accessing period of the reading out cycle even when the electric potential of the data line DL7 drops to +4V, because the electric potential between the gate and channel of the PMOST3 is reversely biased by 0.7V.
