Calcined powder of diatomaceous earth is mainly contained in a mineral layer to be provided on the surface of the synthetic resin foam and plaster, sand and a curing agent are contained besides that. Fine powder of about 150 meshes obtained by calcining/drying is used for the diatomaceous earth and content of the diatomaceous earth in the mineral layer is made 5-95%. A heat insulation material for a trim material or building material which is superior in adhesion and heat insulation properties and light in weight is obtained, by performing natural or hot air drying of the mineral layer.

Title: Amplifier circuit
Inventor: IIZUKA TETSUYA
IPC: H03G3/10
Filed: 1986-02-17
Abstract: PURPOSE:To decrease noise/offset/nonlinearity by connecting a prescribed resistor to a transistor (TR) in a linear circuit using the logarithmic characteristic of the TR. CONSTITUTION:A couple of resistors R1, R2 whose resistance is substantially equal are provided to a couple of input TRs. A couple of resistors R3, R4 whose resistance is substantially equal are provided to emitters of the TRs constituting a differential amplifier. Then new noise is caused by resistors R1-R4, but it is smaller than each noise of a conventional circuit in the order of one digit and a base resistance noise is smaller in the order of 2 digits and Schottky noise is the same. Thus, the output conversion noise is reduced to a degree of the Schottky noise. Thus, noise/offset/nonlinearity are decreased.

Title: Forecasting and encoding system
Inventor: ONO FUMITAKA
IPC: H04B14/06
Filed: 1981-03-06
Abstract: PURPOSE:To shorten a transmission time by efficiently encoding an order signal while considering the order of forecasting levels, by a system which forecasts and encodes a digital signal having level values by a preceding digital signal. CONSTITUTION:A signal level at a reference point is used to forecast the 1st forecasting level at an aimed point. Then, Fig. A shows that while succeeding levels following the 1st one are considered to become higher and higher as their level difference from the 1st forecasting level are less and less, forecasting levels are rearranged with regard to eight level values. Further, Fig. B shows rewritten levels indicating an order signal to the signal level at the aimed point. When the order signal in Fig. B is encoded and transmitted, it is estimated that as the numeral of the order signal is less and less, its probability of appearance is higher and higher without reference to the 1st forecasting level, so mean signal length is shortened, thereby shortening a transmission time.

Title: Unmanned vehicle
Inventor: FUJINAGA NAOMICHI
IPC: G05D1/02
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a two-wheel speed difference type unmanned vehicle capable of stopping without being deviated from a determined traveling locus at the time of emergency stopping. SOLUTION: The unmanned vehicle is constituted of a detection means 1 for detecting the direction of the unmanned vehicle and a control means 2 for controlling the balance of braking of two driving wheels by a prescribed braking means. When the vehicle is turned to right from a required advancing direction e.g. the braking force of the left wheel is increased as compared with that of the right wheel, and when the vehicle is turned to left, the braking force of the right wheel is more increased. When the vehicle is turned to a required advancing direction, the braking force of the right and left wheels is equally controlled. Consequently the unmanned vehicle can be extremely safely stopped without being deviated from the determined traveling locus at the time of emergency stop.

Title: Television receiver
Inventor: KONISHI MASASUKE
IPC: H04N5/21
Filed: 1989-02-13
Abstract: PURPOSE:To reduce the blurring of motion and noise without using a motion detection circuit, to lower the cost of a circuit and to reduce circuit scale by changing the feedback quantity of a cyclic type noise reducer in correspondence to the intensity of an electric field outputted from an electric field intensity detection circuit. CONSTITUTION:When the electric field intensity is strong and the AGC circuit of a tuner is a forward type, the voltage of an RF AGC 9 is made high. Accordingly, an output value K of a feedback coefficient control circuit is made small. Then, as the component rate of the cyclic type noise reducer output, that of a present video signal is larger. Namely, an effect to reduce the noise is small. However, when the motion is large such as the switch of the picture, etc., there is no blurring. When the electric field intensity is weak, the voltage of the RF AGC 9 is small and the output value K of the feedback coefficient control circuit is large. Accordingly, as the component rate of the cyclic type noise reducer output, that of the video signal before one frame is larger and when the motion is large, the blurring is made larger. However, the effect of the noise reduction is made large.

The former projection 2 is preferred to be provided on the inner side of the packing 1.

Filed: 1987-02-18
Abstract: PURPOSE:To prevent exfoliation and cracking of composite body without losing the characteristics of a sintered hard alloy by joining a cemented carbide layer consisting of a carbide essentially composed of WC and iron alloy and sintered cubic boron nitride layer. CONSTITUTION:The cemented carbide layer consisting of 90-96wt.% carbide essentially composed of WC and 4-10% iron alloy and the sintered cubic born nitride layer are joined by using an extremely high pressure device to form the composite sintered body. A thin sheet selected from Mo, W, Ta, and Nb is otherwise interposed between the cemented carbide layer and the sintered cubic boron nitride layer, then these layers are joined. The iron alloy is com posed of 20-50wt.% Ni, 2-20% Co, and the balance iron. The coefft. of ther mal expansion of the WC cemented carbide is thereby equalized to the coefft. of thermal expansion of the sintered cubic boron nitride layer within the range where the characteristics of the WC system are not impaired. This composite sintered body is, therefore, usable without generating the exfoliation by thermal stress, etc.

Abstract: PURPOSE: Not only to attain effective use of a recording medium but also to increase the information capacity of a track by changing clock frequency of recording and reproduction only in case specific single track or multitracks are accessed.  
     CONSTITUTION: A track address which has been transmitted to a floppy disk I/O from CPU is provided to the discrimination circuit D, and it is decided whether the track T is smaller or larger than 30. In case it is smaller than 30, the gate NC into which a standard clock ϕA (6MHz) has been inputted is selected, and in case it is larger than 30, the gate N1 into which a standard clock ϕB (4MHz) has been inputted is selected. Each selected clock ϕA, ϕB has frequency of 16 times as high as a clock signal representing the actual bit cell. Thus recording and reproduction are carried out with high density by changing the clock frequency of recording and reproduction only in case specific single track or multitracks are accessed.

The changing-over of these modes is controlled by the microcomputer of a control part 1. In this way, the copy which is blank on the rear side is obtained even under the selection of the both side copying mode.
