Title: Charge collection type cordless telephone set
Inventor: SAIKAI MASAHARU
IPC: H04M17/00
Filed: 1990-11-30
Abstract: PURPOSE:To offer a charge collection type cordless telephone set exceedingly easy to use for the user of a slave machine by holding a speech loop between a speech destination until specific time elapses even when the signal level of a speech signal between the slave machine goes less than an allowable signal level. CONSTITUTION:A control part 26 cuts off speech in voice between a master machine 1 and the slave machine 2 when a speech infeasible signal of L level is inputted from a speech infeasibility detection circuit 25 in a state where the slave machine is being used and the speech loop with the speech destination is formed. Thence, the clock of elapsed time T after the speech is cut off is started up by starting up a timer circuit 28. When the speech infeasible signal changes to an H level before clocking the elapsed time T, for example, the specific time Tmax of one minute, etc., by the timer circuit 28, it is judged that the speech signal between the master machine 1 and the slave machine 2 is returned to a normal state, and the speech in voice between the master machine 1 and the slave machine 2 can be restored. As a result, the user of the slave machine 2 can restart conversation with an opponent as it is.

Title: Tool for brazing synthetic diamond in gas phase and its production
Inventor: TOMARI HARUO
IPC: B23B27/14
Filed: 1993-12-28
Abstract: PURPOSE:To obtain a brazed tool excellent in strength and heat resistance by brazing a diamond film member through a silicon brazing material, the diamond film member being formed at the action part of a base material for the tool by a gaseous synthetic method. CONSTITUTION:A brazed tool is produced by brazing a diamond film member at the action part of a tool base material comprising a cemented carbide or ceramic through a brazing material comprising silicon or a silicon alloy, the diamond film member being preliminarily formed in a shape corresponding to the outer shape of the action part by a gaseous phase synthetic method. The thickness of the diamond film member is preferably approximately 0.05-1mm. The thickness is controlled to >=0.05mm, because the flank wear width of the tool usually reaches >=0.05mm. The thickness is also controlled to <=1mm, because the performance of the tool is not changed even when the thickness is larger than the 1mm, and because the large thickness requires only a long time for forming the film and does not any advantage.

IPC: G06T1/00
Filed: 1991-12-21
Abstract: PURPOSE:To realize a histogram calculation circuit with high frame rate by constituting two memories so that their roles may be alternated with each other every continuous frame. CONSTITUTION:When a RAM 12 is again cleared while a histogram value is added to a RAM 10, each B input terminal of multiplexers 10, 26 is selected by switching a control signal SEL to a H level and the upper 10 bits of the histogram value are stored in the RAM 12 after the point of the time. Thus, the picture data for one picture is successively inputted and the histogram is determined. Next, the histogram of the picture data for a second frame is determined in the same way. In this case, the roles of the RAM 10 and RAM 12 are alternated. Therefore, a histogram calculation circuit which does not require almost or entirely time to clear memory can be obtained only by providing a memory having capacity which is equivalent to almost one memory in a conventional manner.

Title: Optical disk recording and reproducing device and its method
Inventor: ICHIMURA ISAO
IPC: G11B7/1374
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To record or reproduce information in high density by specifying the thickness of an optical disk and integrally performing focus controls of an objective lens and a front lens while making the total numerical aperture of the objective lens and the front lens a value equal to or above a specific value. SOLUTION: When there is a variation in thickness of a substrate 61, a spherical abberation is generated. Then, in the case a two-group lens having a high numerical aperture is used as a lens unit, when the thickness of the substrate 61 is fluctuated remarkably, the quality of a reproduced signal is impaired largely. Since when the thickness of the substrate is thickened too much, the influence due to a skew becomes large, it is desirable to make the thickness of the substrate to be within the range of 0.1mm to 0.3mm and it is made to be <=0.3mm. An objective lens 27 and a front lens 28 are respectively fixed at prescribed positions. Since they are used by being combined, the numerical aperture of the whole of the lens unit becomes >=0.8 because the multiple of about 1.8 times is multiplied with respect to the numerical aperture of an incident light.
