Patent JP-H03176713-A (JP)
Title: Keyboard
Inventor: NAKADA JUNJI
IPC: G06F3/02
Filed: 1989-12-06
Abstract: PURPOSE:To reduce the size and weight of the keyboard without reducing the using sense of the whole keyboard by thinning the thickness of a key group having low using frequency and thicking the thickness of a key group having high using frequency. CONSTITUTION:Since thick keys are applied to the key group 2 having high using frequency and thin keys are applied to the key group 1 having low using frequency, the compact and light keyboard can be constituted without reducing the using sensor of the whole keyboard. Since the key group 1 having low using frequency is formed as a sheet, key mounting work can be simplified.

IPC: H04N7/15
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To obtain the multi-point video conference system that transmits a video control signal while communicating a long MBE command and reduces video image disturbance caused at changeover of screens or the like. SOLUTION: This multi-point video conference system is provided with plural video conference terminals 2 connecting to the system through channels and with a multi-point video conference communication controller 1 that connects to plural video conference terminals 2 and realizes a multi-point video conference by controlling the video conference terminals 2. The multi-point video conference communication controller 1 has a conference control processing section 6 that uses MBE commands for communication of multi-point control signals with plural video conference terminals 2 and sends the MBE commands and the video control signals and an MBE command division section 11 that divides the MBE commands. The video control signal is transmitted during the transmission of the divided MBE commands by the MBE command division section 11.  Each of the video conference terminals 2 has an MBE command combination section 12 that combines and processes the divided MBE commands upon the receipt of the commands.

Title: Electronic parts for automatic insertion
Inventor: YOSHINAGA TAKASHI
IPC: H01G4/228
Filed: 1990-11-19
Abstract: PURPOSE:To dissolve troubles like cracks of sheath resin, by receiving the initial shock caused by a top face impact at the time of insertion, with the stopper surfaces of a central lead terminal. CONSTITUTION:The inclination angles theta3 of stopper surfaces 2d, 2e of a central lead terminal 2 are smaller than the inclination angles theta1, theta2 of stopper surfaces 1d, 1e, 3d, 3e of lead terminals 1, 3 on both ends. As a result, the stopper surfaces 2d, 2e of the central lead 2 collide with a printed board 6 first at the time of the top face impact. The initial shock caused on the top face is scarcely applied to the lead terminals 1, 3 on both ends, and cracks or the like of sheath resin 5 occurring by the foot-split are hard to be generated. Since a trunk part 2c of the central lead terminal 2 is wider than trunk parts 1c, 3c of the lead terminals 1, 3 on both ends, the adhesion to the sheath resin 5 is large, and deformation of the central lead terminal 2, and cracks of the sheath resin 5, etc., are hardly generated.

Title: Detecting of residual capacity for lead-acid battery
Inventor: OYA YUTAKA
IPC: G01R31/36
Filed: 1986-12-29
Abstract: PURPOSE:To enable detection of residual capacity simply without considering a battery temperature, by determining correlationship between the residual capacity and a differential internal resistance from a lead-acid battery with a known residual capacity to detect a residual capacity based on the correlationship. CONSTITUTION:In a lead-acid battery with a known residual capacity, relationship is determined beforehand between the residual capacity and a differential internal resistance value obtained as gradient from a voltage-current straight line during a short-time large current discharge. Here, the differential internal resistance is defined as gradient of a V-I straight line in which the density of a discharge current per positive unit area of a single cell of battery is obtained within a range of 100-400mA/cm<2> and the V is calculated using a terminal voltage of a combination battery and the I using a battery current. Then, the differential internal resistance is measured for a desired battery of the same type in the same way and the differential internal resistance obtained is compared to the relationship previously determined between the differential internal resistance value and the residual capacity to determine the residual capacity of this battery. This method enables detection of the residual capacity of a lead-acid battery simply at a high accuracy without considering a battery temperature thereof.

IPC: C23C2/02
Filed: 1989-12-05
Abstract: PURPOSE:To reduce a difference in Fe concentration between the plating films on both sides of a plated steel sheet and to prevent deterioration in the workability of the plating films by previously forming ferrous oxides on both sides of a steel sheet so that they are thicker on the thick coating side than on the thin coating side prior to applying a reduction annealing to the steel sheet as a base material. CONSTITUTION:At the time of producing a differentially coated alloying hot dip galvanized steel sheet, prior to the reduction annealing, ferrous oxide is formed on the thick coating side of steel sheet surfaces by 0.3-3g/m<2> coating weight expressed in terms of metallic Fe and also ferrous oxide is formed on the thin coating side by <0.1g/m<2>. By producing a differentially coated alloying hot dip galvanized steel sheet by subjecting the above steel sheet to the reduction annealing, hot dipping, and alloying treatment by the ordinary method, a difference in Fe concentration in the plating film between the thick coating side and the thin coating side can be reduced. By this method, deterioration in the workability of the plating film can be inhibited and the peeling of the plating film at the time of working can be prevented.

Title: Magnetic recording medium
Inventor: USHIGOME HISASHI
IPC: G11B5/702
Filed: 1990-11-20
Abstract: PURPOSE:To obtain an excellent electromagnetic conversion characteristic by a method wherein the range of the quantity of vinyl chloride copolymer resin having a sulfonic acid group is limited for hexagonal plate ferrite magnetic powder and paste dispersion is conducted. CONSTITUTION:Vinyl chloride copolymer resin having a sulfonic acid group is contained in a magnetic layer in the range of 8 to 15 pts.wt. to 100 pts.wt. of hexagonal plate ferrite magnetic powder. In dispersion of the magnetic powder, the adsorptive capacity (total amount of adsorption) of the vinyl chloride copolymer resin needs to be larger than the capacity to be adsorbed of the magnetic powder (BET specific surface X magnetic powder = total amount of adsorption, in the case of Ba ferrite). When it is too large, the efficiency of a mechanical force by a dispersing machine lowers and therefore dispersibility deteriorates to the contrary. When the quantity of the resin is small, the magnetic powder not being adsorbed is left behind, and when it is too large, a state of plate is not attained due to lowering of viscosity. By this method, an excellent electromagnetic conversion characteristic can be obtained.

Then a circuit is connected to a host computer 2 and the result informing massage is sent to the computer 2. Meanwhile the result informing message is immediately sent to the computer 2 when the information showing the abnormal end is confirmed.

Title: Device for estimating friction factor of road surface
Inventor: NISHIRA HIKARI
IPC: B60T8/1763
Filed: 1999-11-08
Abstract: PROBLEM TO BE SOLVED: To enhance estimation accuracy of the friction factor of a road surface by suppressing effects of noises, etc., included in a measured value of a sensor. SOLUTION: By establishing a function (μ-s function) analogous to the characteristic (μ-s characteristic) of road-surface friction factors μ relative to slip ratios λ, a road-surface friction factor μqu corresponding to a slip ratio is computed (7e). An estimated wheel speed xwpr corresponding to the computed friction factor μqu is computed based on a wheel speed xw, driving/braking torque u, the computed friction factor μqu, a wheel load W, and the moment I of inertia of wheels, and an error e is computed by subtracting the estimated speed xwpr from the wheel speed xw (7f). A calibration parameter θpr for calibrating the μ-s function is computed based on the wheel speed estimation error e, the computed friction factor μqu, the wheel load W, and the moment I of the wheels (7j).  The parameter μpr is corrected by being converged in the proximity of a plurality of calibration parameters θi (i=1, 2, etc.), previously established relative to various road surface conditions (7g to 7i). The computed friction factor θqu is calibrated by the parameter θpr to find an estimated road-surface friction factor θpr (7k).
