Title: Cipher communication equipment
Inventor: TSURUMARU JUNICHIRO
IPC: H04W12/04
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To freely change the base station of a radio terminal which belongs to a certain base station to another base station while keeping the security. SOLUTION: When the base station of a terminal 1a is changed from a base station 2a to another base station 2b, the base station 2a sends a tentative basic cryptographic key to the terminal 1a through a radio transmission line 4 by enciphering the key by using the basic cryptographic key peculiar to the terminal 1a so that the tentative basic cryptographic key may not be intercepted by a third person. The base station 2a also secretly sends the tentative basic cryptographic key to the base station 2b through a wired transmission line 3. The base station 2b enciphers a group communication cryptographic key by using the tentative basic cryptographic key and sends the enciphered key to the terminal 1a. The terminal 1a makes communication by enciphering application information by using the received group communication cryptographic key.  Since the tentative basic cryptographic key is used, the terminal 1a can freely change its base station while the security is kept.

Abstract: PURPOSE:To make a displacement enlarging mechanism a guiding mechanism by arranging the displacement enlarging mechanism in point symmetry with a driving source as center so that both the displacement enlarging mechanism and the guiding mechanism can be combined, thereby obtaining an accurate, small-sized, simple and inexpensive fine adjustment mechanism. CONSTITUTION:Among component parts, coupling rods 2, wide elastic fulcrum levers 7, lever holding members and springs 14 are disposed by three at the pitch of 120 deg. with a laminating type piezoelectric element 5 as center. Since the three levers 7 try to uniformize the displacement of the lever adjacent to each other, the displacement of the output ends of the three levers 7 being the enlarged displacement of the piezoelectric element 5 becomes equal. Therefore, since a displacement output table 13 connected to the three output ends is displaced by an equal amount with the fulcrum of the lever connected to a base as reference, there is no factor of the deterioration of straightness in the movement of the table 13. The, the table 13 moves straight up and down.

Title: Manufacturer of positive electrode for secondary cell
Inventor: HAYASHIDA HIDENORI
IPC: C23C18/32
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To improve a filling factor of active material and suppress deformation and breaking of an air-gap and raising by plating a multi-layer body formed by a porous sheet made of thermally disappearing material while specifying a ratio of a volume to an apparent surface area of the multi-layer body. SOLUTION: Thermally disappearing material is the material which is vaporized and eliminated by burning, volatilization, etc., such as forming resin etc. A multi-layer body is formed by winding and bending a sheet made of such material. A ration of a volume to an apparent surface area of the multi- layer body (volume/surface area) is appropriately within a range of 0.0001-0.5. If the ratio falls down below the lower limit of the range, it becomes difficult for plating liquid to penetrate, and if it exceeds the upper limit uneveness is produced. The multi-layer body is plated by electroless nickel as primary plating. In that case, Pd-Sn compound is used as catalyzer. Next, electric or electroless nickel plating is carried out as secondary plating.  After the primary plating, the multi-layer body compactly superimposed is once released and gaps are made so that distribution of the plating liquid is improved at the time of the secondary plating.

IPC: G01N21/57
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To solve such a problem that the appearance of boiled rice dished up on a test tray from an electric rice cooker is mainly evaluated heretofore by an organoleptic method based on the comparison with the appearance of a reference sample but only the relative evaluation with respect to the reference sample is performed and absolute evaluation based on numerical values of a large number of samples is difficult and, since an evaluation item is only 'appearance' and the qualitative difference of appearance can not be evaluated and it is difficult to express a fine feature between the kinds of rice. SOLUTION: A small amount of boiled rice is digitally imaged and the brightness distribution of the digitalized image is analyzed to measure the appearance of boiled rice as three elements of 'whiteness', 'gloss area' and 'gloss intensity' and, from the size and shape of a triangle based on respective measured values, the appearance feature of boiled rice is visually evaluated as a numerical value.

IPC: G01F1/075
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To set a noise margin to be larger in a flowmeter which measures the flow rate of a fluid by using an amorphous magnetic sensor. SOLUTION: Square waves 85 are generated in such a way that an output level is inverted when the voltage of an output signal 81 from the amorphous magnetic sensor 16 exceeds Vtu and when the voltage of a signal 82 is less than Vt1. A pulse signal 86 which becomes an 'H' level by a prescribed width is generated in such a way that the fall edge and the rise edge of the square waves 85 are triggered. Thereby, it is sufficient to set on threshold regarding one signal. As compared with a case in which two thresholds are set regarding one signal as in conventional cases, a margin is obtained in the setting range of a threshold, and the noise margin can be set to be larger.
