Abstract: PURPOSE:To vary the bit constitution of a memory by reading and writing selectively data from and on plural memory cell arrays having the same word and bit constitutions. CONSTITUTION:Since there are two memory cell arrays 1 having the constitution of (8k words)X(4 bits), this memory has the 64k-bit storage capacity as the whole.

Title: Amplitude limiting amplifier circuit
Inventor: NAGATA MINORU
IPC: H03G11/00
Filed: 1987-05-21
Abstract: PURPOSE:To cope with a wide input signal level range and a frequency range by applying positive feedback to limit an output current supply of a main differential amplifier under the unity gain in response to the output current of a sub-differential amplifier. CONSTITUTION:The current flowing to transistors (TRs) Q15, Q16 of the sub- differential amplifier B is controlled by a collector output of TRs Q11, Q12 of a main differential amplifier A. Then the current flowing to the TRs Q13, Q14 of the amplifier A is controlled in response to a voltage generated between the base and emitter of the TRs Q15, Q16, emitter resistors (R) 15, 16 and resistors R13, R14 to form a feedback loop to apply positive feedback only around the center of the output amplitude range with respect to the amplifier A. The loop gain is set to the unity or lower. Thus, the circuit copes with a wide input signal level range and frequency range.

Title: Piezoelectric vibrator
Inventor: KAWAURA KUNINORI
IPC: H03H9/17
Filed: 1989-05-16
Abstract: PURPOSE:To make the characteristic of a three frequency voltage controlled oscillator stable by forming a drive electrode respectively to opposed major faces of a piezoelectric body cut out of a rotation X plate of a lithium tantalate piezoelectric single crystal and specifying a 3rd-order resonance level with respect to a 1st-order resonance level when the drive electric field is applied to the drive electrode. CONSTITUTION:A drive electrode 3 is formed respectively to opposed major faces of a piezoelectric body cut out of a rotation X plate of a lithium tantalate piezoelectric single crystal. When a drive electric field is applied to the drive electrode 3, a 3rd order resonance level Rs3 is lowered by a value equivalent to 30OMEGA with respect to a 1st-order resonance level Rs1. Thus, it is possible to eliminate jitter or to reduce the jitter generating rate, and the performance of a 2-frequency and a 3-frequency VCO (3-frequency voltage controlled oscillator) including, e.g. a low frequency band is made stable.

Title: Asphalt pavement material using spent molding sand
Inventor: KATOU TOMIMASA
IPC: E01C7/18
Filed: 1979-09-22
Abstract: PURPOSE: To contemplate an improvement in the stability of asphalt pavement and the effective utilization of spent molding sand, by a method wherein the spent molding sand having a particle size of not more than a specified size is used as part or main component of fine aggregate.  
     CONSTITUTION: Spent molding sand having a particle diameter of not more than 2.5mm such as CO 2 -molding sand or self-curing molding sand is used as part or main component of the fine aggregate of an asphalt pavement material. Thus, the spent molding sand can widely be distributed as the pavement material. A strong alkalinity which the spent molding sand possesses is gradually diluted of itself, and hence a problem on waste disposal will be solved. The spent molding sand is not merely a substitute for ordinary sand, but also can be used as a good pavement material which enhances stability.

Title: Dot impact printer
Inventor: TAKAHASHI KATSUNORI
IPC: B41J29/46
Filed: 1988-05-18
Abstract: PURPOSE:To prevent the deterioration of print quality or faulty reading by providing a comparator which compares an oscillation pattern from an oscillation detector with an oscillation pattern stored in a memory and interprets whether or not these patterns coincide. CONSTITUTION:If a character symbol code VC for detecting a broken pin is entered, a comparator 7 compares reference oscillation pattern information VR transmitted from CPU 1 with detected oscillation pattern information VD obtained when any appropriate character symbol is printed, and interprets whether or not these informations coincide to output an interpretation signal VC. However, the oscillation pattern information of an output signal VV from an oscillation detector 5 is stored in a memory 4 as reference oscillation pattern information. Therefore, if a printing pin 22p is broken, any change in the output signal VV from the oscillation detector appears. Immediately, it is detected whether or not the pin is broken by comparing an oscillation pattern of the output signal VV during operation with the reference oscillation pattern. Consequently, any appropriate measures can be taken to deal with the broken pin, and thereby the deterioration of printing quality and faulty reading can be prevented.
