When the current is over the reference which is the effective discharging current 0.1 μA/cm necessary for the discharging, only a green diode is lighted, to inform by the green luminous colour, that the discharging performance is satisfied. When the current is about 0.1 μA/cm, both of the red and green diodes are lighted, and the attention is aroused by the orange luminous colour. When the current is less than the reference, only the red diode is lighted to give the warning.  A device can be made compact and simple by including a main circuit in a main body case, and mounting the detecting windows respectively opposite to the charging plates 8, 9 at the plus and minus sides.

Title: Multiplication circuit
Inventor: KAJIWARA MASANORI
IPC: H03H17/02
Filed: 1988-11-02
Abstract: PURPOSE:To attain bit processing from the side of the most significant bit by inputting a control signal to an AND circuit at the n-th operation being the least significant bit location of a PCM data so as to initialize the low-order k-bit among (k+n) bits in the output of an adder circuit. CONSTITUTION:The operation is repeated for n-times, in which an adder circuit 2 adds a coefficient data in k-bit from a gate circuit 1 and a data in (k+n) bits resulting from the data in (k+n-1) bits from the 2nd MSB (the bit next to the most significant bit) added with '0' to the LSB (least significant bit) in the content stored in a shift register 4 and the output of the adder circuit obtained is stored in the shift register 4. Then the result of multiplication between an n-bit PCM data and a k-bit coefficient is outputted serially from the shift register 4. Then the low-order k-bits in the (k+n) bits being an output of the adder circuit are initialized to zero by inputting a control signal to the AND circuit 3 at the n-th operation when the PCM data is located at the LSB position. Thus, the processing of bits is processed in the order of the MSB.

Title: Package for semiconductor device
Inventor: UCHIDA HIROYUKI
IPC: H01L25/00
Filed: 1988-11-01
Abstract: PURPOSE:To simplify the assembling process by making a through-hole in at least one layer and filling the through hole with ferroelectric thereby enabling formation of a capacitor in a package and eliminating connection of capacitor parts with the surface of the package. CONSTITUTION:A ceramic substrate 1 has a lamination structure where a through hole is made in the intermediate section and the through-hole is filled with ferroelectric 2 such as Ti2BaO3 or TaN. The ceramic substrate arranged with the ferroelectric 2 is metallized at the opposite end faces to form electrodes 3 which are connected electrically with a bonding lead 5 and an outer connecting lead 6 through metal poles 4. By such arrangement, capacitors are formed in the package thus reducing noise occurring in the ground potential and the source potential. It is particularly effective when a large electrostatic capacitance is required for a large semiconductor device package. Electrostatic capacitance can be varied not only through selection of the ferroelectric but through variation of the thickness of the ceramic substrate and the density of the through-hole.
