Title: Heat-sensitive diazo recording material
Inventor: NAGAMOTO MASANAKA
IPC: G03C1/52
Filed: 1981-02-23
Abstract: PURPOSE:To improve the capacity of heat color formation of a heat-sensitive recording material comprising a diazo compound and a coupler, by adding a substance containing water of crystallization which releases said water at a high temperatures. CONSTITUTION:A heat-sensitive recording layer is formed by coating one or more layers of a mixture of a diazo compound generally used for diazo photosensitive paper, a coupler such as phenol, a heat-fusible substance, a binding agent and other auxiliary ingredients, etc. This heat-sensitive recording layer is mixed with a substance containing water of crystallization such as a hydrate of an inorganic metallic compound, or a hydrate of an organic acid or its metal salt. It is desirable to use a colorless, white or light-colored substance which releases part or all of its hydrate water at temperatures of 50-200 deg.C. Since the hydrate water released from the substance during thermal recording serves as water, the coupling reaction is remarkably expedited and the heat responsiveness of the heat-sensitive recording material is improved.

Title: Hydraulic sender
Inventor: IWATA SATORU
IPC: F01M1/20
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To prevent friction and seizure such as occur in the case that a sliding spring is in direct contact with a resistor, by installing a rolling element in a contact point of the sliding spring with a resistor. SOLUTION: In a sliding spring 6, a wheel 9 is installed at the contact point with a resistor 7. Thereby the contact with the resistor 7 becomes one point with the wheel 7. It rotates in accordance with the movement of the sliding spring 6, so that friction is little and seizure can be evaded. In spite of the vertical movement of the sliding spring 6, the vertical position of the wheel 9 does not change, and it moves in the horizontal direction with respect to the resistor 7. In order not to generate friction at the contact point with the resistor 7, only the moving range of the sliding spring may be considered, so that a rolling element such as a semicircular body and a circular arc body may be used instead of the wheel 9.

Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To provide crosstalk reduction countermeasures which enable a gradational display by a pulse-width modulation system(PWM) while relaxing restrictions imposed on a time-constant element and eliminating noise appearing at a scanning electrode when a selection period is switched. SOLUTION: The driving waveform for signal electrodes Segm is generated by switching 1st and 2nd basic waveforms W1 and W2. The 1st and 2nd basic waveforms W1 and W2 are symmetrical about the ground level VM of liquid crystal driving, a differentiation coefficient is 0 when a voltage at the time of the switching of the selection period has the ground level of liquid crystal driving, and a finite differential coefficient is obtained even in a period other than the period of switching of the selection period. The 1st and 2nd basic waveforms are switched halfway between the switching time of the selection period and the selection period to impose pulse-width modulation. The resistance of signal electrodes is made larger than that of scanning electrodes to round the edge of the driving waveform for the signal electrodes SEGm.

Title: Cordless communication system
Inventor: IGURA HAMAMI
IPC: H04W88/04
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To extend a speech range from a master set to a slave set by using a slave set in the speech range so as to relay a radio signal when a slave set of a communication object is outside the speech range from the master set. SOLUTION: When slave sets, e.g. 5, 6 among plural slave sets 4, 5, 6 are at a distance disabling direct radio communication from a master set 3, the master set 3 sends a relay request to the slave set 4 within the reception range from the mater set 3. The slave set 4 receiving the relay request uses its inter- slave-set communication function to relay a radio signal from the master set 3 to a communication object master set 3 slave set, e.g. the slave set 6. Thus, the master set 3 is able to communicate with the slave set 6 at a position out of direct reach of the radio signal via the slave set 4. Thus, the speech range from the master set 3 to the plural slave sets 4, 5, 6 is extended and the user effectively utilizes a small output slave set outdoor.  Furthermore, in this case, the position of the slave set 4 is fixed and the communication between the master set 3 and the slave sets 5, 6 at a remote location is conducted via the slave set 4 to extend the communication range, then the relay procedure is simplified.

Title: Corona discharger
Inventor: KATAYAMA MASAHIRO
IPC: H01T19/00
Filed: 1980-02-29
Abstract: PURPOSE:To secure an effective prevention of adhesion of a toner to a nonpicture region, by securing an electrifying condition under which the surface potential of the nonpicture region after formation of a latent image becomes to a level at which an attachment of toner is more difficult than that of the potential at the bright part of the picture region. CONSTITUTION:The discharge wire 2 is distributed so as to extend in the axial direction and in opposition to the circumference part of the photoreceptor drum 1. The center part of the surface of the drum 1 is the picture region 3 and the both ends of the surface are the nonpicture regions 4 each. And the area opposing to the region 4 of the wire 2 is covered with the dielectric substance 5. As a result, the corona current given from the wire 2 is reduced at the region 4 with a lower surface potential than the region 3. Accordingly a considerable difference of potential is caused between the region covered with the dielectric substance and the region that is not covered with the dielectric substance. This difference of potential differs according to the resistance and the thickness of the dielectric substance to be selected in accordance with the desired electrifying conditions. In such way, a surface potential is set at the region 4 and after formation of an electrostatic latent image with such a level at which an attachment of toner is reduced.

IPC: F27B1/10
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To get an equal quality of a product, by connecting each bottom output part of two or more material supply pipes at least two of plural material supply pipes with the opening to the top of the prebaking chamber of an exhaust pipe. SOLUTION: Exhaust gas passing through the stacked layer 59 of a furnace floor 51 is discharged via an exhaust pipe 12 after entering a material supply pipe 1. In each exhaust pipe 12, the temperature of exhaust gas is measured by an exhaust gas temperature detector 13. If the stacked layer 67 within a lower kiln 65 is on the same level in the circumferential direction shown by a solid line, the exhaust gas in each exhaust pipe 12 is detected as roughly the same temperature. But, if the level in the circumferential direction of the stacked layer 67 shown by a tow-dot chain line is unequal, the temperature in each exhaust pipe 12 varies from that of the other.  Accordingly, if a user grasps the relation between this temperature difference and the height of the stacked layer 67 in advance, the stacked layer 67 within the lower kiln 65 becomes equal in circumferential direction, consequently the products obtained after baking become equal in quality.
