Abstract: PURPOSE:To provide a high temp. adsorptive filtrating material having heavy metal adsorbing ability by using natural ore of manganese dioxide as a base material, particulating it, subjecting to heat treatment and acid treatment, and by using granular manganese dioxide including crystal structure other than beta type thus obtained. CONSTITUTION:Natural ore 1 of manganese dioxide is in beta type crystal structure with low adsorption activity, but can be acquired at low cost and is equipped with high hardness and mechanical strength. After the ore 1 is crushed, a certain extent of particle sizes are selected to provide granular substance 2. This undergoes modifying treatment to enhance the heavy metal adsorbing ability. This treatment provides modification of crystal structure by heat treatment and modification of surface structure by acid treatment. That is, the substance is modified into gamma type crystals having adsorption activity with modification of surface structure of the grains, and at the same time, the lost crystal water is reformed. This is followed by removal of residual acid by water rinsing. Thus a high temp. adsorptive filtrating material is obtained, which includes gamma type crystal structure, is equipped with heavy metal adsorbing ability, and can be acquired at low cost.

Title: Frame converting circuit
Inventor: SAKATA TATSUMI
IPC: H04L25/05
Filed: 1989-06-29
Abstract: PURPOSE:To offer a system to be highly reliable by not containing data to influence a malfunction or mis-synchronization in one part of data to be read. CONSTITUTION:To a frame converting circuit, an initial value input circuit 19 to write an arbitrary initial value to each address of a memory 11 designated with a read address signal each time the data are read as a high-speed data signal according to the read address signal from the memory 11 is provided.

Title: Piezoelectric transformer
Inventor: TAGAMI SATORU
IPC: H01L41/22
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To obtain a piezoelectric transformer in which the transformer performance can be modified without requiring any modification in the shape of a piezoelectric when diversified requirements are imposed on the step-up ratio or the efficiency of the piezoelectric transformer or regulation is required for the output performance of an inverter circuit when it is mounted on a system employing the transformer. SOLUTION: The ratio of polarization at the driving section and the power generating section of a piezoelectric to the saturated polarization is differentiated between the driving section and the power generating section. The step-up ratio and the efficiency of a transformer exhibit different characteristics as compared with those of a piezoelectric where both the driving section and the power generating section are subjected to saturated pogarization. Since the characteristics vary differently depending on the extent of polarization at the driving section and the power generating section, performance of the transformer can be modified using a piezoelectric of identical shape.

Title: Semiconductor integrated circuit device
Inventor: SATO KATSUYUKI
IPC: G11C11/34
Filed: 1986-07-18
Abstract: PURPOSE:To eliminate the undesired peak current at the time of turning on a power source and to stabilize an action by preventing the two CMOS inverter circuits of a latch mode constituting the flip-flop of respective bits of a counter circuit from going to a latch condition until the electric power source voltage arrives at a prescribed voltage. CONSTITUTION:From a level detecting circuit to the gate of N channel MOSFET Q7 and Q9, a control signal WK made into a high level when the absolute value of an electric power source voltage Vcc and a substrate back bias voltage -Vbb arrives at the high level is supplied. To the gate of P chan nel MOSFET Q3 and Q5, an inverting signal by an inverter circuit N4 of the control signal WK is supplied. For such a reason, clocked inverter circuits CN1 and CN2, in the initial period of the starting of a dynamic RAM in which the control signal WK is made into the low level, are both made into a non- action condition since N channels MOSFET Q3 and Q5, a P channel MOSFET and the Q7 and Q9 come to be the off condition. Thus, the undesired peak electric current at the time of turning on the power source can be eliminated.

Abstract: PURPOSE:To improve the track density 1.5-2 times, by shaping the crosssection of an optical disc into a waveform having a cycle shorter than the diameter of a light spot, and providing its mountain parts and valley parts as information track parts in concentric circles or spirally. CONSTITUTION:A conventional track guide groove is disused, and mountain parts and valley parts are used as center parts of tracks, and the track pitch is made shorter than the diameter of the light spot.

In Fig., a1, a2- indicate centers of mountain parts, and b1, b2- indicate centers of valley parts. Only mountain parts are tracked when the polarity of a tracking control circuit is set to a certain direction, and only valley parts are tracked when the polarity is made opposite. Consequently, the track pitch is doubles equivalently, and the track density is improved 1.5-2 times.

Abstract: PURPOSE:To detect anything unusual in an accelerator sensor, by making up the accelerator sensor so as to judge as trouble when a signal value of the accelerator sensor goes beyond the specified value in time of the accelerator being in a full closing position as well as when the outputted signal exceeds the usual value in time of the accelerator being in a full opening position. CONSTITUTION:Even if an accelerator is in a full closing position, a signal S1 of a potentiometer 1 has a value of V0 and a signal S2 processed at a porcessing circuit 3 is outputted from an output terminal 9 as an accelerator signal. A comparison circuit 4 is composed of an operation amplifier 6 and resistors R1 and R4, and when the potentiometer 1 is normal, a signal S3 is always in a low level but if something wrong happens and therefore the signal S2 comes to below the V3, the signal S3 comes to a high level, turning on a transistor 7 of a display unit 5 and indicating the occurrence of something trouble with a lamp 8. Doing like this, an accelerator sensor is always monitored and thereby all drawbacks can be diagnosed with certainty.

IPC: G03B27/73
Filed: 1988-07-05
Abstract: PURPOSE:To prevent the black part of a character, etc., from shifting in color by mounting a mask negative plate for black on a photosensitive recording medium in contact and imaging the reflected or transmitted light of an image formed on a color mask negative plate on the photosensitive recording medium by an optical system through the black mask negative plate. CONSTITUTION:The black mask negative plate 40 is placed on the photosensitive recording medium 24 in contact and then, for example, a red mask negative plate 22R is positioned and arranged; and the photosensitive recording medium 24 is exposed to the reflected or transmitted light of the image on the red mask negative plate 22R by the optical system through the black mask negative plate 40. The photosensitive recording medium 24 is exposed to a green mask negative plate 22G and a blue mask negative plate 22B with green light and blue light similarly to the exposure of the red mask negative plate 22R. When the exposure is completed three times, a black latent image and latent images of the three primary colors corresponding to the mask negative plates are formed on the photosensitive recording medium 24 one over another without any color shift. Consequently, the color shift of black thin lines used frequency for the printing of characters is eliminated and an image of high quality is obtained.
