Title: Preparation of porous metal
Inventor: ICHIKAWA MASAHIDE
IPC: C25F3/00
Filed: 1982-12-06
Abstract: PURPOSE:To obtain a sponge like porous metal, by passing a DC or an AC current through a conductive metal material while using an electrolytic bath containing an electrolyte comprising halide to perforate the surface of the metal material or perforate said metal material so as to reach the interior thereof in a porous state. CONSTITUTION:An anode material and a cathode material are arranged in an electric cell as electrode materials as shown by a drawing and an electrolytic bath containing halide such as chloride (e.g., NaCl) or fluoride (e.g., RF) is received in said cell. In this case, for example, same Pb metal materials are used as the aforementioned anode material and the cathode material and, for example, an AC current is flowed through both electrodes. As a result, Pb on the surface of the electrode material is melted as chloride (PbCl2) to partially make perforations. This phenomenon is generated here and there and a porous metal is entirely obtained. Because this action is alternately repeated by the action of an AC power source, many perforations are made even if a current is succeedingly flowed for a longtime.

Title: Webbing take-up device
Inventor: IMAI KEISUKE
IPC: B60R22/28
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To absorb energy severely without increasing the size of a take-up shaft in radial direction. SOLUTION: A take-up shaft 24 is divided into three parts in the axial direction, and the engaging pins 44 of holder parts 20 and 22 are fitted closely into the engaging holes 32 formed in a spool 18. Also a groove part 30 is formed in the spool 18 in the circumferential direction and, when a rotational force beyond a specified limit acts on the spool 18 in the webbing pull-out direction, a thin wall part 34 is broken and the engaging pin 44 is advanced into the groove part 30. By this, both side parts of the groove part 30 is deformed, and energy is absorbed. Thus the take-up shaft 24 needn't be more increased in size in the radial direction than when energy is absorbed by the deformation of the take-up shaft 24 in the radial direction.

IPC: A61B3/113
Filed: 1992-07-16
Abstract: PURPOSE:To make highly precise glance detection by finding a glance by the glance detecting device from a function based upon an observer's pupil diameter and glance correction data. CONSTITUTION:The glance correction data (glance correction coefficient) for correcting a detection error in glance due to the individual difference of the eyeball are collected to form a (calibration) visual field area. A CPU detects the position of a Purkinje image. Plural border points between the pupil and iris are detected as the center position of the pupil and the pupil diameter is also calculated; and the interval between two Purkinje images is calculated from their positions and the coordinates of two points of a diagonal of a rectangle are stored in a glance detecting circuit. The reliability of the calculated positions of the Purkinje images and pupil center is decided on the basis of the contrast of an eyeball image or the size of the pupil. This reliability information is calibration data. Then, the distance between the ocular of a camera and the eyeball is calculated from the interval between the Purkinje images and the angle of rotation of the eyeball optical axis is corrected to find the glance.

Title: Method for preventing creak noise in bearing
Inventor: OKADA SUSUMU
IPC: F16C19/24
Filed: 1988-08-29
Abstract: PURPOSE:To check the generation of a creak noise by means of easy treatment by spreading an oil for grease for bearing lubrication or oil with similar quality thereto on the cylindrical roller rotating surface or the circumferential edge of the cylindrical roller in a bearing inner race. CONSTITUTION:An oil film 5 consists of a kind of oil same as the lubrication grease filled on the circumferential edge of a cylindrical roller and this oil is spread on the entire circumference of a cylindrical roller rotating surface 6 and the circumferential edge of a cylindrical roller 3 in a bearing inner race 1. An amount of spreading oil is 0.14-5.5% of grease amount for lubrication or 0.003-0.095mm of an oil film thickness spreading over the entire circumference of the cylindrical roller rotating surface in the bearing inner race. Thus, as a creak noise is eliminated even though a radial clearance is not made smaller, the life of the bearing is not reduced. Also its control becomes easy because there is no need of reducing the control range for the radial clearance. The life of the bearing is not reduced even under a severe condition like high temperature, high rotational speed and high load because there is no need of the use of grease with low viscosity inferior in heat resistance.

Title: Method for varying encoding level of digital data transmitted at constant transmission rate between transmitter and receiver
Inventor: CHARRIERE PATRICK
IPC: H04L1/00
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To evade the occurrence of data loss in the case of causing abrupt quality variation of a transmission channel by preventing switching from the encoding level of a rank (m) to the encoding level of a rank m+q for a fixed time of non-zero length after the quality of a receive signal is adapted to the encoding of a level m+q. SOLUTION: In a GSM type network, the encoding level of digital data transmitted at a constant transmission rate between a transmitter and a receiver is varied. The encoding level is determined depending upon the quality of a signal received by the receiver. It is prescribed that the encoding level of a rank 0 provides the minimum protectivity of transmit data. Arbitrary switching from the encoding level (0<m<n-1) of the rank (m) to the encoding level (0<m+1<=n-1, where (q) is positive) of the level m+1 is prevented for non-zero time length (time delay) when the quality of the transmission channel corresponds to the encoding of the level m+1 to evade frame loss.

Filed: 1985-09-30
Abstract: PURPOSE:To prevent the mis-setting of a parity of a receiver side equipment by receiving a data sent from an equipment at the sender side so as to discriminate a parity set to the equipment at the sender side thereby discriminating the parity of a data frame from the equipment at the sender side. CONSTITUTION:A parity discrimination circuit 5 counts the bit number of logic 1 included in a data part 11 and a parity bit 12 based on a clock signal 9 generated in matching with the data transmission speed of the equipment at the sender side. When the count is an even number, it is discriminated that the parity set to the equipment at the sender side is an even number parity and when the count is an odd number, it is discriminated that the parity set to the equipment at the sender side is an odd number parity. A central processing unit 6 informed of the even or odd number parity sets the parity to the communication LSI 7 of the equipment at the receiver side so that the parity is equal to that set to the equipment at the sender side. Thus, the operation by an operator is facilitated and the reception error by mis-setting is suppressed.

Abstract: PURPOSE:To prevent the area overflow of a stand-by combination/organization file by displaying a candidate member to be deleted which is extracted based upon a threshold rate and reference information on a terminal at the time of registering a new member in the file. CONSTITUTION:At the time of preparing a program, an operator outputs a registration command to a central processing unit(CPU) 2 in order to register the program in a stand-by combination/organization file 4. At the time of receiving the information, the CPU 2 compares the activity ratio of the file 4 up to a current point of time with an upper limit value (a) previously specified at the time of preparation. When the activity ratio does not exceed the upper limit value (a), registering processing is executed. When the activity ratio exceeds the upper limit value (a), a management record is retrieved and a member which is not protected at its writing and has the oldest reference date is extracted and displayed on a terminal equipment. The operator determines that the oldest member is to be deleted or not based upon the displayed information.
