Title: Frame synchronizing system
Inventor: AZAYA TAKAO
IPC: H04J3/06
Filed: 1977-10-14
Abstract: PURPOSE:To shorten the resynchronizing time by just increasing the register length and through a simple circuit constitution by adding the register to memorize the correlation result along with the means to select the bit at the fixed digit position in each frame and then to secure the correlation between the frames. CONSTITUTION:Input signal S1 is detected for the frame pattern digit at frame pattern detecting part 3, and the correlation is secured with every bit through correlation detector circuit 4 between the frame detection result and the preceding frame detection result. And this result is stored in register 5. In case no correlation is secured, the another correlation is secured with the subsequent frame. While in case the correlation is secured, the number of the frame with which the correlation is secured is counted at control circuit 24. And when the count value exceeds a fixed value and only one bit of the digit securing the correlation is left in register 5, the digit securing the correlation is positioned at the rear end of register 5 with the subsequent frames. Thus, the detection start digit position is always coincided with the digit position where the correlation exists, and then the synchronous lead- in performed.

Inventor: FUJITOMO KATSUMI
IPC: F16F15/04
Filed: 1980-09-03
Abstract: PURPOSE: To prevent noise and vibration of automobile by setting the right and left spring constants at a value larger than the upper and lower spring constants of a bearing cushion for a propeller shaft of a triple split type which is adjusted to a value suited to reduce the vibration of a center shaft.  
     CONSTITUTION: The spring constant K 1  of the bearing cushion 10 is set at a value suited to reduce the vibration of a front shaft throughout the circumference while a tubelar rib section 14 with a spring constant K 2  is solidly formed on the right and left of an inner bent surface 13 of spring pieces 12 and 12. Consequently, the right and left spring constants K 2  is now larger by the spring constant K 2  of the rib 14. Thus, depending on the spring constant K 2 , the angular change is reduced at the joint between a front shaft and a rear shaft to lower the secondary couple developed between both the shafts during the starting thereby preventing the vibration. This can prevent both the noise and virtation.

Title: Resin mold type semiconductor device
Inventor: MIURA MASATAMI
IPC: H01L23/48
Filed: 1982-07-15
Abstract: PURPOSE:To obtain an economical and deformation-free resin sealed type semiconductor device which assures excellent solderability of lead wires by forming the exposed region of copper tab as an Ni layer while the exposed region of copper lead as a solder layer. CONSTITUTION:The external tin plating can be eliminated by previously executing the Ni plating to an anode tab 22 and the solder dipping to the lead wires 23-25 and thereby the cost can be reduced remarkably. Unlike the tin plating,  the tab and lead wire are not deformed even after the solder dipping and mounting work can be simplified. In addition, the tab 22 is chemically more stabilized  because it is covered with an Ni oxide film and excellent solderability can be obtained since the lead wire is dipped into solder. Thereby mounting to the  printed circuit board becomes easy. According to this structure, an automatic  manufacturing line can be configured.

Title: Variable rated voltage generator
Inventor: HIBINO HIROSHI
IPC: H02K19/36
Filed: 1988-05-20
Abstract: PURPOSE:To maintain the ground impedance at a proper value by connecting predetermined armature windings in parallel and shortcircuiting a corresponding ground element automatically. CONSTITUTION:When connection terminals U2 and X1, V2 and Y1, W2 and Z1 are connected through a connection board 30, induced voltage is added on each armature winding of a generator 10 to produce line voltage EK. Resistors R1, R2 are inserted in series between the neutral point and the ground point of the generator 10 thus limiting ground current to I. When connection terminals U1 and U2, V1 and V2, W2 and X1 and O, Y1 and O, W1 and O are connected, the armature windings are connected in parallel to produce line voltage EK/2 from the generator 10. Since the connection terminals OA, OB, OC are conducted with the connection terminal O, the ground resistor R2 is shortcircuited. When connection of terminal is modified and the armature winding is selected, rated voltage can be modified to a desired level and the resistance between the neutral point and the ground point can also be modified, and thereby the maximum ground current can be controlled to a constant level at all times.

Abstract: PURPOSE:To attain an adjustment with high accuracy by a simplified constitution, by adjusting the direction of an image at one unit reading column, using a turning mirror. CONSTITUTION:Since the image 2' of a unit reading column 2 is formed on the photodetecting plane of an optical detector 6, and the optical detector 6 consists of a line sensor in which plural photodetectors are arranged in a columnar shape, the accurate reading can not be obtained until the adjustment is performed so as to coincide the direction (a') and (b') of the images 2' with the arranging direction of the photodetectors. At this time, the above adjustment is performed by a half mirror 4. The half mirror 4 is formed as the turning mirror capable of turning around a turning axis XX', and the turning axis XX' is positioned at a twisted state against the column forming direction (ab) of the unit reading column 2. So that the image 2' formed on the optical detector 6 by turning the half mirror 4 around the turning axis XX', changes in the direction shown in broken line, the adjustment is completed by fixing the half mirror at the position where the image 2' coincides with the direction of the line sensor.
