Title: Electrical apparatus
Inventor: SATOU TAI
IPC: H01L23/52
Filed: 1982-10-14
Abstract: PURPOSE:To prevent transmission delay by Mirror effect by separating the wirings for electrical signals which are changed each other in the relation of reversed phase and arranging approximately the lines for sub-signals sent from the same signal source. CONSTITUTION:The ground wire GND, 4-bit signal lines A1-A4, B1-B4, clock phi1, power supply line Vcc are approximately wired in parallel on a SOS substrate, and the signal lines A1-A4 are connected to the poly-Si leadout lines D1-D4 through windows C1-C4. Simultaneously, the signal lines A1-A4 in which signals may be changed reversely are not approximated and the signal lines B1-B4 in which signals may change in the other timings are alternately provided. Thereby, the rising/falling times can be improved by about 40% or more due to reduction of effective capacitance between the adjacent wirings. For the signal lines A0-A2, the sub-signal lines A01-A22 are respectively disposed in both sides of wiring. For A1, the same electrical signal is applied to A11, A12 and a current of A11, A22 is set to 1/2 of A1. At this time, operation of A1 occurs quicker than that of A11, A12 and the rising/falling time is improved by 70% or more than the conventional time. This structure is very effective for IC having a small capacity of wiring to the ground and a large wiring capacitance and is capable of remarkably improving signal delay.

Title: Magnetic head
Inventor: DEKURA YOSHINORI
IPC: G11B5/10
Filed: 1983-09-30
Abstract: PURPOSE:To enable formation of a check groove having high accuracy of gap depth with a head formed by melt-spraying a ceramics layer on the surface by sticking a material which is different from the melt-spraying material and has small specific resistance to the part where a magnetic tape does not travel so that electric discharge machining with less burring is made possible. CONSTITUTION:Parts 10 and 11 where a magnetic tape 6 does not travel are preliminarily masked and a wear resistant ceramic is melt-sprayed to an electromagnetic converting part 9 and thereafter the sprayed ceramics part is conversely masked and a different material having small specific resistance is stuck by melt-spraying or the like to the parts 10, 11 where the tape 6 does not travel. If such material is molded, the check of a butt gap depth 12 with good accuracy is made possible as electric discharge machining is easily accomplished. The electromagnetic characteristics is correspondingly stabilized. If, for example, an Al2O3-TiO2 material is used for the ceramics material in the part where the magnetic tape travels and a TiO2 material is used in the non-traveling part, the high wear resistance of the former and the electric discharge machinability of the latter are made compatible.

Title: Instantaneous water heater
Inventor: SUGAWARA YASUKUNI
IPC: F24D17/00
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To prevent hot water discharge quantity from a hot water discharge tap from decreasing at the time of occurrence of hot water discharge during instantaneous water heating operation by stopping a circulation drive means upon reception of a hot water discharge tap use detection signal from a heat source unit side during instantaneous water heating operation executed by circulating hot water by the circulation drive means. SOLUTION: An instantaneous water heater 14 comprises primarily a hot water supply pipe 16, a return pipe 17 and a controller 18, and the hot water supply pipe 16 supplies hot water supplied by the heat source unit 12 to an end tap 28 through a circulation pipe 15. When an instantaneous hot water switch 30 of a remote controller 13 is turned on, a controller 18 sets instantaneous hot water set temperature at a temperature equal to hot water discharge set temperature. Then, if temperature of hot water within the return pipe 17 becomes not higher than the instantaneous hot water set temperature, a circulation pump 23 is activated to start instantaneous water heating operation so that hot water is circulated in the direction designated by a solid line arrow.  If during instantaneous water heating operation the end tap 28 is opened and the heat source unit 12 starts combustion operation, operation of the circulation pump 23 is interrupted to stop instantaneous water heating operation upon reception of a combustion signal.

Title: Bellows-shaped hose and its manufacture
Inventor: YOSHITOMI SHINGO
IPC: F16L11/11
Filed: 1990-07-07
Abstract: PURPOSE:To manufacture a bellow-shaped hose having comparatively high strength, large expansion and contraction and deformation amount and little resistance at the time of deformation by sticking respective frame components to a hose main body in the state of stretching in tension in the radius direction. CONSTITUTION:A hose main body 1 is composed of a base 2 formed with a cylindrical knitted web and a rubber coverying layer 3 formed integrally with said base, and circular rings 4 are disposed as frame components at equivalent intervals inside the hose main body 1. As large tension is not applied to the hose main body 1 among the rings 4 when external force is not applied particularly, its shape is not fixed actually and the hose main body forms a soft structure with large recesses and projections on the inner surface. However, when the rings or the like on both ends of the hose are pulled in the axial direction, the main body is stretched in the linear shape and the recesses and projections on the inner face of the hose get comparatively smooth. Further, when the rings 4 of the hose are overlapped, the main body can be pulled into the extremely thin state. Thus maintenance and transportation are extremely simple and easy, and a wide range of applications are available for the expanding and contracting sections. Also, the hose can be bent easily into the corner shape.

Abstract: PURPOSE:To prevent foreign mattes such as dust from sticking at a light receiving surface and to adjust easily a focus of an image pickup element with respect to a photographing lens by containing the image pickup element in a barrel main body having a photographing lens forward. CONSTITUTION:When a replacement lens tube 4 is fitted on an electric camera main body 1, a fitting part 2 of the camera main body is fitted in a fitting part 12 of a barrel main body, and the barrel main body 4 is slightly rotated. Thus a connecting terminal 3 is electrically connected to a connecting terminal 13. After incident light from a subject through a photographing lens 5 is converted into an electrical signal by an image pickup element 9, it is transmitted to the camera main body 1 through the connecting terminals 13 and 3 and recorded on a magnetic recording medium through a signal processing circuit. At this time, since the image pickup element 9 is contained in the tube main body 4 having the photographing lens 5 forward, foreign matters such as dust will not stick on the light receiving surface of the image pickup element 9.
