Title: Production of abrasion-resistant composite aluminum member of cylindrical shape
Inventor: HINO HARUMICHI
IPC: B22D11/00
Filed: 1981-11-19
Abstract: PURPOSE:To provide extremely high abrasion resistance on the inside circumferential surface and to maintain machinability on the outside circumferential part by fluidizing the state in solid-liquid coexistence of abrasion resistant powder and an Al alloy in a molding die by the insertion of a plunger die thereby molding the same into a cylindrical shape. CONSTITUTION:An Al alloy and a powdery abrasion-resitant material are agitated at the temp. region in solid-liquid co-existence of the Al alloy, and the half melt thereof is supplied into a molding die 1. Immediately thereafter a plunger  die 4 is inserted into the hole 2 of the die 1 and the half melt is molded to a  cylindrical shape under pescribed pressure. Thus on account of the effect of the abrasion-resistant dissimilar material existing preferentially on the inside circumferential surface, the part near said inside circumferential surface has extremely high abrasion resistance.

Title: Preparation of stable suspension for internal use
Inventor: IWAYAMA YOUJI
IPC: A61K9/10
Filed: 1983-10-03
Abstract: PURPOSE:To obtain the titled suspension of hardly water-soluble or water-insoluble drug, having high physical, chemical and biological stability, by adding a nonionic surface active agent as a suspension assistant and if necessary a clouding point-raising agent such as edible saponin to a natural polysaccharide used as a suspension agent.

Filed: 1986-08-06
Abstract: PURPOSE:To increase an accuracy in a distance measurement by performing an automatic calibration by changing over an object to be measured to a reference delay line at suitable time intervals midway through the measurement. CONSTITUTION:When a changeover switch 16 is thrown to the side of a transmitting and receiving antenna 3, reflected microwave from an object 4 is inputted to a signal processor 2 via a microwave transmitter and receiver 1 and a distance output signal Sd is outputted from an output correcting circuit 17.

The output correcting circuit 17 compares a value thus measured with the reference distance of the line 15 accurately measured in advance and outputs distance output signals Sd wherein the measured values of the object thereafter are calibrated in accordance with deviations thus obtained. Accordingly, the measured value with a high accuracy is always obtained.

Title: Clutch or brake
Inventor: KATO KATSUHIDE
IPC: F16D55/36
Filed: 1993-07-28
Abstract: PURPOSE:To make subtle control achievable in a simple structure by constituting one side friction body with a frictional part different in a diameter and a supporter by way of an elastic member, and setting up a contact surface with the other side friction body in a position different in the axial direction. CONSTITUTION:In the case of using as a brake, supposing a driving side friction body 8 is shifted to the left, two small diametral friction plates 8a and 9a at both driving and driven sides adhere closely to each other, and a spring 11 comes into contact with the friction plate 8a at the most right end. When it is further shifted, two large diametral friction plates 8b and 9b at both driving and driven sides adhere closely to each other, and a spring 12 comes into contact with the friction plate 8b at the most right end, and thereby braking force at a single item of a small diametral clutch part (a) by means of elasticity of the spring 11 is gradually increased. Two axial distances D3 and D4 cane to equal to each close adhesion length of both these friction plates 8a and 9a (8b and 9b), braking force is suddenly increased by the sum total between braking force at the small diametral clutch part (a) and that at the large diametral clutch part (b) by elasticity of the spring 12, and further contact pressure at both these clutch parts (a) and (b) increases and thereby the braking force goes up. Therefore a subtle operation of half-brake and half-clutch is thus easily performable.

IPC: H04N19/48
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To reduce processing time of image data by allowing respective CPUs to perform compression processing of respective divided image data. SOLUTION: Respective divided image data are subjected to compression processing in respective CPUs. In this camera, a dividing means 3 divides image data to an upper area and a lower area of a screen after the image is picked up. Here, in the image data, e.g. pixel values in an 8×8 block continuously stand in line and pixel values in an adjacent block follow them. Then, the means 3 simply divides data for one screen into two parts that are data A for the upper area of the screen and data B for the lower area. Compressing means 4a and 4b respectively perform compression processing of the data A and B. On the other hand, when the image is displayed expanding means 6a and 6b respectively perform expansion processing of the data A and B which are compressed and stored.
