Abstract: PROBLEM TO BE SOLVED: To perform a point click system without putting the hands away from a keyboard by positioning a cursor with one thumb and selecting an image with the other thumb while placing the fingers of both the hands except the thumbs at their home keys when operating the cursor with both the hands. SOLUTION: A cursor controller 12 (track ball 32, function start button 31, and lower button 33) is provided at a palm rest part 9 provided on a main housing 1 which is closer to a user oppositely from the keyboard 11 so that both the hands of the user reach a cursor controller 12 during operation on the keyboard 11. To operate the cursor with both the hands, the cursor is positioned with one thumb and an image specified with the cursor is selected with the other thumb while the fingers of both the hands are left at their home positions. To operate the cursor with one hand, the one hand is put away from the home positions, the cursor is positioned with the one hand, and an image is selected.

Title: Polymer useful as blood treating agent and molding thereof
Inventor: TERAMOTO KAZUO
IPC: A61K31/785
Filed: 1984-03-19
Abstract: PURPOSE:To remove selectively the cholesterol in blood by a vinyl polymer having the arom. nucleus into which the functional group expressed by the specific formula is incorporated as a side chain and the molding thereof. CONSTITUTION:A vinyl polymer having the arom. nucleus into which the functional group expressed by the formula is incorporated as a side chain and the molding thereof constitute a blood treating agent. The result is much better if the polymer is crosslinked and if the polymer is reinforced by poly alpha-olefin as represented by crystalline PP or PE as the mechanical strength is improved with the latter. The immobilizing density decreases if the surface area is too small in the case of the molding but if the surface area is too large, the liquid passability of the column in which the molding is packed decreases and therefore the preferable surface area is 0.01-50m<2>/g.

Title: Rockfall prevention support with hinged strut
Inventor: MITSUKURA TADAKATSU
IPC: E01F7/04
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To easily install stone guards even if a mountain side slope is unsteady by attaching a hinged strut to the support of a stone guard used for a rockfall measure to prevent road disasters. SOLUTION: When a stone guard structured so as to be embedded in a concrete foundation is to be installed on rock mass, ground excavation is difficult, and the slope lacks the strength of a support foundation due to shortage of front earth pressure. In this case, the embedding portion of the stone guard is eliminated and the lower portion is fixed with an anchor, and the top is attracted by a wire rope from an anchor installed on the mountain side. Therefore, the attraction by a wire rope helps a hinged strut prevent the support from falling toward the mountain side. The hinged strut, even if the slope of the mountain side is unsteady, helps install vertically easily the support.

Filed: 1980-04-21
Abstract: PURPOSE:To miniaturize the power source, by selecting an optional one of plural unit input circuits and then supplying an input power source containing the current capacity equivalent to above-mentioned one unit to the selected unit input circuit. CONSTITUTION:The input power source 11 has the current capacity equivalent to one unit of the unit input circuits 17a-17d and is incorporated into the controller 10. Then both the input instruction and input address are supplied to each unit input circuit via the bus line 12. The input address circuit 15 gives an indication to the corresponding selector 18 to select the corresponding unit input circuit and supplies the power source 11 via the line 12. Accordingly, a small amount of capacity is enough for the power source, and thus the power source can be miniaturized to be incorporated into a controller.

Next, the upward and rightward movements of arrow (c), (d) of the bar 4 cause the clampers 5, 6 to go over the dies 7 and the stage 25 respectively. In the descending of an arrow (e) of the bar 4, the clampers 5, 6 unclamp the respective works and place them on the dies 7 and the stage 25 respectively. Further, in the upward and leftward movement of arrows (f), (g) of the bar 4, the clampers 5, 6 return to the home position, thereafter, they repeat these operations.

Title: Liquid crystal display device
Inventor: AOKI ISAMU
IPC: G02F1/133
Filed: 1986-03-12
Abstract: PURPOSE:To improve the uniformity of display density by adding a multiplying means for an AC signal frequency to a liquid crystal display device equipped with a matrix type liquid crystal display element and a liquid crystal driving LSI which oscillates internally to generate an AC signal for the inversion the polarity of an impressed voltage for the driving of the display element. CONSTITUTION:The LSI (I) 4 for a scanning electrode which operates in master mode generates the AC signal of low frequency as initially designed and this signal is inputted to an AC signal frequency multiplying circuit 6 and multiplied to, for example, 200Hz which is about 6 times. An LSI (II) for a scanning electrode in slave mode and an LSI 3 for display electrode operate while inverting the polarity of the impressed voltage at the output frequency of the AC signal frequency multiplying circuit 6, e.g. 200Hz. Consequently, the frequency of the AC signal is increased to raise the upper limit of a display frequency band and narrow down the display frequency band, thereby reducing an irregularity in display.

Title: Semiconductor device and manufacture thereof
Inventor: NAKANO MOTOO
IPC: H01L27/02
Filed: 1982-03-30
Abstract: PURPOSE:To obtain a stabilized overvoltage protective device by a method wherein a pair of discharge electrodes of polycrystalline or amorphous Si or low melting point metal are arranged at the prescribed interval, and they are operated at the desired voltage using the vacant space closed by an interelectrode region and an insulating film. CONSTITUTION:An etching is performed on the SiO2 film 2 located on an Si substrate 1 using a reactive ion, and concavities 3 and 3' are provided accurately with the corner of a concavity 21 formed at a right angle. A poly Si layer 22 is selectively formed striding over a barrier 21, and P or As is doped. Then, the above is covered by a PSG5, and a laser beam 23 is irradiated. As the PSG5 is transparent to a laser beam, it is absorbed into the poly Si 22, the layer 22 is rapidly heated up and fused, the upper layer part of the layer 22 located above the barrier 21 is fused and flowed away and the layer 22 is divided into layers 4 and 4'. The PSG 5 and the SiO2 film 2 are hardly heated up while the above procedures are being performed and they can maintain their original form, thereby enabling to form a cavity 6 in the short time of a millisecond or less. As the operating voltage can be optionally established taking the quality of material of the electrodes, the interval between the electrodes and the like into consideration, an overvoltage protective device which is operated stably can be obtained.

Title: O2 sensor heater control device
Inventor: TOYODA KATSUHIKO
IPC: G01N27/409
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To stabilize the output characteristics of a sensor and to prevent the sensor and a heater from deteriorating by performing the duty control of the conduction state of a heater so that the temperature of an O2 sensor enters an active temperature range. SOLUTION: An O2 sensor heater control device 12 is provided by setting the map of a duty value for temperature based on the temperature of a first O2 sensor 34 being detected by a temperature sensor 152 to a control means 124. A control means 124 sets the duty value for temperature to 100% until the temperature of a heater 150 exceeds a lower-limit temperature for duty control when an engine 2 performs cold start, thus increasing the temperature of a first O2 sensor 34 to an active temperature at an early stage, and performs control so that the duty value for temperature can be decreased at a constant ratio as an upper-limit temperature approaches when the lower-temperature is exceeded for protection so that an allowable upper-limit temperature cannot be reached.  Further, when the lower-limit temperature is close, the duty value for temperature is increased and duty control is made so that the temperature of the heater 150 cannot reach the lower-limit temperature or less.
