Title: Image blanking circuit
Inventor: MATSUTANI MICHIHIKO
IPC: H04N3/20
Filed: 1984-10-25
Abstract: PURPOSE:To enable a stable and clear disappearing of image by a simple constitution by connecting a control electrode and a main electrode of a switching element to set/stand-by power sources, and let the element become on by a potential difference bewteen the two power sources when cut off, and let it generate a pulse for blanking. CONSTITUTION:As the switching element a PNP semiconductor TR20 is provided, of which emitter is connected to the set power source 4, base to the stand-by power source, and collector is grounded via a load 23. In a state where power is not cut off (prior to t1), the TR20 is in off state because source voltage characteristics of the power supplies 3 and 4 are in a relation as shown by marks (a) and (b). When the power is cut off at a time t1, a voltage of the power supply 3 starts to lower, to become a value to make with the supply 4 a voltage differential that is equal to a base-emitter differential of the TR20 (at a time of t2). At this time the TR20 becomes on, in a collector of which a pulse for blanking is generated. The blanking continues until a time t3 when an deflecting system no longer works, to suppress any image disarrangement.

Title: Input circuit
Inventor: UNENAI TSUKASA
IPC: H03K19/0175
Filed: 1983-11-29
Abstract: PURPOSE:To attain the change of the threshold level of an input circuit in response to the change of a drive level for a logical IC, by selecting the optimum threshold value of the logical input of said logical IC in accordance with the output level of each independent drive circuit which drives the logical IC. CONSTITUTION:The output of an NAND gate 8 and the output of an NAND gate 7 are set at H and L respectively at a time point (a) when an electric power supply is applied. Thus a transistor (TR) 9 is turned on and the gate of a TR4 has the same level as a TR3. These levels of the TRs 4 and 3 change in response to the drive level. Then the output of the gate 7 changes to H from L when it exceeds the threshold value of a HT inverter at a time point (b). Furthermore the output of the gate 8 changes to L from H. As a result, the TR9 is turned off and the input of the TR4 is fixed at a GND level and becomes insensitive to the drive level. In case the drive level is set at ''2'', the HT inverter output has no change. Therefore the gate level of the TR4 is equal to that set at the time point (a) and varies in response to the drive level.

Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To make the respective gaps between a printed circuit board and a magnet and between this printed circuit board and a back yoke uniform by mounting and fixing the printed circuit board to the mounting boss on the back yoke side. SOLUTION: The printed circuit board 8 is held by a positioning boss 9 on the side of the magnet 62 fitted to a supporting shaft 1 and the mounting boss 92 on the back yoke 7 side and is adhered and fixed to the mounting boss 92.

The mounting boss 92 fixed with the printed circuit board 8 at its end face is longer in the axial direction than the positioning boss 9 and, therefore, the mounting accuracy at the time of fitting to the supporting shaft is higher and the degree of inclination with the supporting shaft induced by press fitting or shrinkage fitting of the positioning boss 9 is negligible.  Then, the gaps between the printed circuit board 8 and the magnet 62 and between the printed circuit board 8 and the back yoke 7 are respectively kept uniform.

Title: Interruption circuit
Inventor: SAKATA TOSHIFUMI
IPC: G06F9/48
Filed: 1985-10-08
Abstract: PURPOSE:To reduce the load of software to be used for interruption processing by forming a level detecting circuit for detecting a level signal, a time setting circuit for setting up the detecting time of the detecting circuit to various lengths and a trigger circuit for outputting an interruption signal. CONSTITUTION:When the state of an input terminal 4 is a high level, the high level state is detected and all the contents of shift registers 5 of (n) stages are previously set up to high level output state, so that only the output of the shift register in the final stage becomes the high level after passage of (n-1)X(t)hr. Thereby, the output of a NAND circuit in the trigger circuit 1 is turned from the high level to the low level at the passage of (n-1)X(t)hr. When a clock signal is inputted, the output of the shift register in the final stage is turned from the high level to the low level, so that the output of the trigger circuit 1 is turned to the high level independently of the state of the input terminal 4. The output of the trigger circuit 1, i.e. an interruption signal is detected by a CPU to control the flow of a program.

Filed: 1985-10-08
Abstract: PURPOSE:To obtain a lead frame for a semiconductor device having a heat- dissipating effect and little thermal stress to a semiconductor element by each using specific materials for a lead member and a tab. CONSTITUTION:In a semiconductor device manufactured by employing the lead frame, a large-sized semiconductor element 7 is fixed onto a tab 6 formed by a low thermal expansion material such as a 42 alloy (Fe-42% Ni) through a precious metal layer 8.
