Title: Linear amplifier device
Inventor: TANAKA MASAJI
IPC: H03F3/04
Filed: 1983-03-08
Abstract: PURPOSE:To obtain a linear amplifier without using any resistor and any adjustment by forming this amplifier with an operational amplifier, a capacitor and a switching means. CONSTITUTION:An input signal is applied to an inverting input terminal (-) of the operational amplifier 4 from a signal input termianl 1 via the switching means 6 and the capacitor 7. The amplification factor of the operational amplifier 4 is decided by a capacitance value C1 of the capacitor 7 and a capacitance value C2 of a capacitor 8 for feeding back output. The switching means 9 is interlocked with the switching means 6, and when the means 6 is connected to the position A, the means 9 is connected to the position A similarly and the means 6, 9 are designed to be connected to the position B at the same time conversely. When both means 6, 9, are connected to the position B, the charge stored to the inverting input terminal (-) of the operational amplifier 4 because of leakage current or the like is eliminated. When both means 6, 9 are connected to the position B, the substantial amplifying function is obtained.

Title: Method and equipment for judging cell type of battery
Inventor: CHIYAARUZU SUTANTON SUTEFUENZU
IPC: G01R31/36
Filed: 1994-02-11
Abstract: PURPOSE: To correlate the characteristic of a battery with at least known characteristics of first and second cell types, generate an output signal showing the cell type of the battery according to it, and easily judge the cell type of a battery during recharging. CONSTITUTION: A current source 64 can generate a current of prescribed or known intensity, and selectively add this to a battery 62 through a switch 74. In a charging system 60, a comparator circuit 66 compares the battery voltage of the battery 62 with a reference voltage VT added to a line 78, and generates a signal 70 showing a cell type to an output line. The circuit 66 can be executed by use of an analog electronic circuit or digital electronic circuit. When the signal 70 shows that the battery 62 is of alkali cell type, and recharging is thus impossible, the signal 70 opens the switch 74 to interrupt the charging current to the battery 62.

Abstract: PROBLEM TO BE SOLVED: To reproduce a high naturalness and high quality voice with an over- poweringly low bit rate while suppressing quality deterioration by specifying a frequency band of an input voice to the band of about 5 kHz and balancing an information amount incorporated in the voice with coding efficiency. SOLUTION: For instance, when a coding system of frame length 10 ms, a bit rate 7.8 kbits/s is designed, a voice signal is low-pass filter processed to be band limited to 5 kHz or below. Analytic frame length is 110 samples, and this is equivalent to nearly 10 ms. The number of sub-frames is made 2, and look-ahead is made 1 sub-frame 5 sm. A linear predictive parameter is coded by two stage vector quantization using moving average prediction, and 1 bit is used to moving average predictive mode switching, and 7 bits are used to a first stage, and second stage is divided to a low-order and a high-order, and 5 bits are used to respective orders. When 11.025 kHz sampling is used, in an adaptive code book, 8 bits are allocated to an adaptive code book index, and 5 bits are used for a second sub-frame.

Title: Preparation of ga-as single crystal
Inventor: KATSUMATA TOORU
IPC: C30B15/00
Filed: 1983-03-10
Abstract: PURPOSE:To prepare a Ga-As single crystal of high quality having uniform characteristics of resistance distribution contg. no growth striation and uniform distribution of dislocation, etc. by adjusting a proportion of Ga to As in the melt of a raw material to a proportion of the compsn. of the congruent, and pulling out thereafter a single crystal through a liquid sealing material. CONSTITUTION:An evaporation loss of As is calculated from precise measurements of the amt. of starting materials, i.e. Ga and As to be mixed, the weight of pulled up single crystal, and the weight of the remaining melt of the starting materials. The starting materials are adjusted wherein a Ga-As melt admixed with excessive As exceeding the evaporated loss is decompressed from the pressure applied thereon to 1 atm by maintaining its temp. at the melting point. The excessive As is vaporized, and when the vaporization ceases, namely, when generation of foams from the melt is ended, a congruent compsn. is formed from the melt. The seed crystal is allowed to contact with the melt in this state, and a Ga-As single crystal is grown by the pulling up operation of the crystal. In this case, a high pressure sealing pulling up method is adopted using B2O3 as the sealing liquid.

IPC: G02B7/02
Filed: 1985-03-01
Abstract: PURPOSE:To prevent a position shift in image point due to humidity variation and a shift of an optical axis due to the pressing force of a lens frame by the outer peripheral surface of a high-hygroscopicity lens and the engagement surface of the lens frame at the same angle and calculating the angle from the quantity of variation in lens external diameter and the quantity of the shift in image point. CONSTITUTION:A slanting surface 3 and the engagement part 5 of the lens frame 4A which engages it are formed at the same angle theta on the outer peripheral surface of one high-hygroscopicity biconvex plastic lens 1A among plural incorporated lenses. In this case, theta=tan<-1>(DELTAD/2DELTAf), where DELTAD is the quantity of variation in the external diameter of the lens and DELTAf is the quantity of the shift in image point. Consequently, even if the lens 1A deforms owing to variation in humidity, the shift in image point is prevented and the image point is made coincident with an image formation surface at any time; and the lens surface deformation and the shift of the optical axis due to the gap formation between the lens frame and lens are prevented with pressing force to the lens frame 4A.
