Patent JP-S5456777-A (JP)
Title: Semiconductor device
Inventor: UMEHARA KAZUO
IPC: H01L21/822
Filed: 1977-10-14
Abstract: PURPOSE:To secure a correlation between the resistance and the current amplification ratio of the transistor to make constant the medium potential for the power amplifier, by dividing the same seminconductor substrate via the isolating region and providing the vertical PNP transistor to one side of the divided substrate and the resistance to the other side respectively. CONSTITUTION:N-type epitaxial layer 7 grown on P<+>-type Si substrate 1 is partitioned into two regions at P-type region 11, 11' and 11''. And the normal vertical PNP transistor is formed within the right partition, and the resistance is formed within the left partition respectively. In other words, N<+>-type region 17 and 17' are provided across the resistance region to secure an electric contact between metal electrode 21 and 22, and region 13 of epitaxial layer 7 enclosed by P<+>-type region 5, 10 and 15 excluding the area near region 17 and 17' is used for the resistance. Here, region 5 is isolated with N-type region 3 buried at the boundary part between substrate 1 and layer 7. In such way, the resistance value depends on the space between region 5 and 15, and also the current amplification ratio depends on the space between region 4 and 14 which form a transistor. Thus, a correlation is secured to each other.

Title: Receiver for radio paging
Inventor: SHIMANUKI YOSHITARO
IPC: H04B7/26
Filed: 1987-05-22
Abstract: PURPOSE:To elevate a paging rate for a paging with a long selective paging signal, without changing the function of a transmitting side by majority-deciding a signal, which a receiver side received plural times and stored, by bit unit. CONSTITUTION:The receiver receives end demodulates the signal from a transmitting station by a RF part 1 and a demodulating part 2, and at first, decodes a paging number word, and collates it with the number, stored previously in a paging number ROM 4, and when both the paging numbers coincides, it shores a successively received information word in a RAM 7. Afterward, for instance, when it receives the same paging number at the position of the selective paging signal for subsequent two frames, it stores them in the RAM 7 similarly. When the reception of the selective paging signal of a third time is completed, a data decoding control part 6 drives a majority deciding part 8, and reads out the bits one by one from the three RAMs 7 respectively, and decides them by majority. Thus, the respective bit can be correctly identified, and even when the selective paging signal is long, the probability of a data unreceiving due to a bit error is reduced.

A voltage proportional to the voltage of the main capacitor 1 at the time of the end of light emission, namely, the same voltage as the voltage VA for the end of light emission is set as the voltage VD. When a light emission start signal is turned on, an Xe tube 2 is excited by a trigger means 10 to start light emission. When the Xe tube 2 emits light, the voltage of the main capacitor 1 is quickly reduced and the voltage V is reduced also. When the voltage VA is reduced to be lower than the voltage VD, the comparing means 8 is inverted and a light emission stop means connected in series to the Xe tube 2 is started to stop the light emission of the Xe tube.

Abstract: PURPOSE:To prevent solder bridging in an area near a drive roller introduction part by boring a hole in the central part of a fixed guide and enabling a lower part pipe of a solder guide to move up and down freely and engaging a weight running through the center of the fixed guide. CONSTITUTION:The central part of a fixed guide 18 fixed with a holding fitting extended from a base is bored while a lower part pipe 20 of a solder guide 19 is arranged to move freely. Therefore, the lower part pipe 20 floats an opening 21 of the fixed guide 18 upwardly when driving force is added by the rotation of a drive roller in the arrow direction and solder is piled up in an inner space of the solder guide 19 or not capable of passing through easily there. At the same time, a weight 17 floats up in a similar manner since it is engaged with the solder guide 19. This eases the resistance of a drive roller emission part 16. This construction makes it possible to reduce the generation of loss in soldering work since it is possible to prevent a zigzag state of solder generated in an area near the drive roller emission part.
