Patent JP-H112112-A (JP)
Title: Crank case of portable four-cycle engine
Inventor: ZAMA RYOJI
IPC: F01M11/06
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent a lower edge of a crank web from soaked in an oil face, by projecting a lower part of a bearing boss to a cooling fan side, and comprising a side wall provided with a recesss part, at a cooling fan side, to reduce the change of the oil face between an inclined condition and an upright condition. SOLUTION: In a crank case 9 at a cooling fan side, a lower part of a bearing boss 9a is projected to a cooling fan 7 side, and a recessed part for reducing the elevation of an oil face F1 is formed. When a portable four cycle engine 1 is inclined to the cooling fan 7 side, an lubricating oil in an oil reservoir 13 is flown into the recessed part of a side wall 9c at the cooling fan side, so that the elevation of the oil face F1 can be reduced for that amount. That is, the recessed part of the crank case 9 at the cooling fan side and a inclined wall 10c of a crank case 10 at a non- cooling fan side are formed in such manner that the increase and decrease of a variable amount of lubricating oil at the cooling fan side and that at the non-cooling fan side are almost agreed with each other to a central axis 3a of a piston.  That is, the oil face F1 passes through an almost P point regardless of an inclining direction, so that an interval L1 between the oil face and the lowermost edge of the crank web 4b becomes almost uniform.

Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To save the power consumption of a wireless keyboard. SOLUTION: A mode bit indicating the presence or absence of the operation of a mode key is inserted next to the start bit of transmission data of a wireless keyboard. When a composite operation of the mode key and another key is executed, this format is converted into a communication data format constituted of a status code indicating the state of all mode keys, key data, check sum, and stop bit following 14 a mode bit '1'. When the state of all the mode keys is OFF, and another key is operated, this format is converted into a communication data format in which the status code is omitted.

IPC: G01G19/02
Filed: 1989-03-27
Abstract: PURPOSE:To shorten a waiting time for the measurement and to improve efficiency of a storing process by calculating a weight of vehicle corresponding to an elastic extension for the hanging cable of a gage according to the weight of vehicle and outputting the calculated weight of vehicle to an output device. CONSTITUTION:When the vehicle 12 is loaded on the gage 16, a chain 17 is extended by the weight of vehicle 12 and the gage 16 is displaced downward from a reference ground surface GL to push a detecting rod 22, thereby a pulse corresponding to this displaced amount is oscillated by pulse oscillators 1, 2. A pulse corresponding to the revolution of a driving shaft 19 caused by backlash of the gear on a transmission 20 is oscillated by the pulse oscillator 3 as the pulse for correcting the displacement caused by the backlash. These pulses are counted by a pulse counter 4 and the quantities of these pulses are sent to a CPU 5 as displacement data, whereby the weight of vehicle is calculated. By the CPU 5, whether the calculated weight of vehicle 12 is exceeded the weight limit or not is decided, and an alarm signal is sent out from an interface unit 6 to a display device 7 and a sound outputting device 8.

Title: Optical disk device
Inventor: TOGO KENJI
IPC: G01N21/95
Filed: 1987-03-27
Abstract: PURPOSE:To divert the basic function of information reproduction and to inspect whether or not there is a defect on the surface of an optical disk by focusing a laser beam on the surface of the substrate of the optical disk and discriminating the quantity of reflected light detection during surface scanning. CONSTITUTION:A CPU 10 which selects an inspection mode with a switch 11 changes the target point of a focus servo 7 to the surface of the transparent substrate of the optical disk and focuses the laser beam on the surface of the substrate. In this state, the laser beam makes a surface scan on the substrate surface by the movement of the optical head 1 and the rotation of the optical disk, and a defect discrimination part 12 monitors a tracking error signal. In this state, if there is a defect such as a flaw at a beam irradiation point, diffraction is caused by projections and recesses and the reflected light spreads to the environment, so that the quantity of reflected light returning to the optical head 1 decreases. Behavior variation of the reflected light due to a difference between the smooth substrate surface and the presence of the projections and recesses as a defect can be detected most sensitively as level variation of a tracking error signal obtained from the photodetection output of the optical head 1.

IPC: H01L29/78
Filed: 1990-03-22
Abstract: PURPOSE:To form a gate electrode characterized by excellent step coverage, low resistance and excellent frequency characteristics by forming a low resistance metal layer on at least the side wall in a recess part formed in an insulating part on a semiconductor substrate, growing low resistance metal thereon, and forming an electrode. CONSTITUTION:A silicon oxide film 2 is deposited on a semiconductor substrate 1. A hole is opened for the length of a gate electrode in the above described oxide film 2 in a region which is to become the gate electrode. Thus a recess part is formed. Then, e.g. a tungsten film 3, a titanium film 4 and gold 5 are sequentially deposited. Thereafter, the metal gold 5 in a part other than the side of the recess part is removed by ion milling. The titanium film 4 is exposed in a part other than the side wall of the inside of the recess part. When gold plating is performed, the plating is grown only on the gold 5 on the side wall of the inside of the recess part, but the plating is not grown on the titanium film 4. As a result, the gold plating 6 which is grown from the side wall of the inside of the recess part completely fills the inside of the recess part. The length of the extending part is suppressed to the minimum degree. Finally, with the gold plating 6 as a mask, the titanum film 4 and the tungsten film 3 are removed by dry etching, and the gate electrode is completed.
