Title: Method for transforming one thermal source into work
Inventor: NAKAJIMA YASUTO
IPC: F03G7/06
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To enhance an efficiency, and thereby obtain its great output by letting electricity be included in the cycle of a thermal engine, and transforming one thermal source into equivalent works. SOLUTION: A stationary electrode 4 is mounted in the inner bottom wall surface of a piston cylinder 1, and a movable electrode 5 is mounted in the inner surface of an opposite piston 2. The voltage of 1KV per interval, for example, is applied in between both the electrodes 4 and 5 when there exists the pressure P of energy cycle at the point (W), and gas is thereby electrically charged, and similarly let shortcircuiting develop between both the electrodes 4 and 5, and the afore-said gas is thereby discharged. In electrically charged working medium in the piston cylinder 1, the direction of dipole moment for each molecule consisting of gas for example, is arranged in one direction, as a result, heat is thereby generated, and the pressure (X) of energy cycle is increased up to an '0' point. Subsequently gas is adiabatically expanded, and when its pressure comes to a point (W), the temperature of gas is lowered down, and its pressure thereby comes to a point (Y).

Filed: 1989-12-02
Abstract: PURPOSE:To obtain a riding lawn mower having excellent overall performance by placing an engine at a low position in the middle of the front and rear wheels and under the driver's seat and placing a radiator in a rear bonnet in lateral direction. CONSTITUTION:An engine E having heavy weight is placed at a low position between the front and rear wheels 4, 3 utilizing the vacant space under a machine frame. A radiator 6 usually placed in longitudinal direction close to the front or rear side of the engine E is placed in a rear bonnet 2 in lateral direction. The center of gravity of the whole machine is lowered by the structure and, at the same time, the engine E is displaced from the rear bonnet 2. The distance between the shafts of the front and rear wheels 4, 3 can be decreased to an extent corresponding to the absence of the radiator 6 at the front and rear side of the engine E. Nevertheless, the machine body can be lowered by the absence of the engine E in the bonnet and the height of the rear bonnet 2 can be suppressed to the necessary minimum level.

Abstract: PURPOSE:To enable a vacuum cleaner to be easily operated even by a visually handicapped person or at a dark place, and prevent the occurrence of an unexpected power change due to an unexpected touch on a switch or a dial during cleaning by providing a hose end bend pipe with a built-in sound sensing section having a sensor to detect human voice, and controlling a control circuit for an electric blower according to the detection result of the sensor. CONSTITUTION:When an intake port 9 is first kept in contact with a floor and a grip section 5 is lifted for staring a cleaning work, a sound sensing section 4 comes to the highest position of a cleaner and nearest a worker's mouth. At this stage, the worker utters and the sound of an utterance is transmitted from a voice introduction hole 7 to a human voice sensor 6. As a result, the sensor 6 detects the human voice sound, and the result of the detection is inputted to a control circuit. According to an output signal matching input from the aforesaid control circuit, an electric blower M is controlled, for example, for drive, stop, weak intake, strong intake or the like. It follows, therefore, that the manual operation of a switch, a dial or the like is never required, and the cleaner can be well controlled and operated even by a visually handicapped person or at a dark place. Also, the elimination of erroneous cleaner operation due to manual handling can be ensured.

Title: Magnetic head
Inventor: FUJITAKE TOSHIYUKI
IPC: G11B5/60
Filed: 1990-11-22
Abstract: PURPOSE:To enable high-density recording by mounting a non-magnetic section at a specified position of a slider so as to reduce the sectional area of magnetic flux path at a position where the magnetic circuit of the slider is formed. CONSTITUTION:The end section 47 of a slider 29 is projected from a surface 49 on the side reverse to a flying surface 33, and a non-magnetic member 51 is set up on the surface 49 through glass bonding. A notch 53 matched with the end section 47 is formed in the non-magnetic member 51, and the non- magnetic member 51 is fast stuck onto the whole surface of the surface 49 of the slider 29 because the end section 47 is inserted into the notch 53. The relationship of x>=y holds in size (x) in the left and right direction of a core 34 and size (y) in the same direction of the end section 47 of the slider 29 at that time, and the relationship of m<=n holds in size (m) in the vertical direction of the lower end section 45 of the core 34 and size (n) in the same direction of the end section 47 of the slider 29. The sectional area at a C section, i.e., the path of magnetic flux 25, is throttled by holding such dimensional relationship. Accordingly, the inductance of a coil can be reduced without decreasing the number of turns of the coil, and deterioration of S/N ratio representing magnetic recording characteristics can be prevented.

Filed: 1991-11-29
Abstract: PURPOSE:To prevent hillock and disconnection of aluminum when an aluminum wiring is already formed in a semiconductor chip which is a foundation substrate by depositing an insulating film while raising a formation temperature from a specified value. CONSTITUTION:A semiconductor chip is put in a reaction filter of a CVD device which is heated to 150 deg.C. It is left as it is for 1 to 20min. After the temperature of a wafer becomes constant, reaction gas (SiH4-NH3-N2O) is introduced and, at the same time, the temperature is made to rise at a rate of 150 deg.C/min and held at 300 deg.C after 10min. An Si-O-N film is made to grow to a thickness of about 200nm while the temperature rises up to 300 deg.C from 150 deg.C, and is made to grow to the thickness of about 800nm at 300 deg.C. Since the Si-O-N film formed in this way has little stress in a lower layer and is dense in an upper layer, it is possible to prevent generation of aluminum hillock and to realize good passivation efficiency.

Title: Radio selective call receiver with battery saving function
Inventor: KIDO TORU
IPC: H04B7/26
Filed: 1993-12-16
Abstract: PURPOSE:To prevent the decrease in the battery saving efficiency when the mode transits to the frame synchronous signal collation mode resulting from mis-detection of a bit rate. CONSTITUTION:When a bit rate detection section 16 detects a bit rate (e), the mode transits to the frame synchronous signal collation mode. The result of bit rate detection while 4-words are counted by a timer count section 18 is latched in a latch section 19 as a latch signal (j) and the signal (j) is outputted as an output signal (k) to a control section 13 through a gate section 20 on the 5th word. When the bit rate is detected, the mode is unchanged and the data are received continuously, and when the bit rate is not detected, the mode is changed into the preamble collation mode, that is, the intermittent reception mode. In the case of the continuous reception mode, the mode continues till a longest word count 20 is obtained and then the mode restores to the preamble collation mode because the frame synchronous signal is not detected. When a frame synchronous signal detection section 15 detects the frame synchronous signal, its detection signal (c) is used to change the mode into the address collation mode.
