Title: Frequency characteristic adjustment circuit
Inventor: YAMAGIWA KAZUO
IPC: H04N5/93
Filed: 1986-08-26
Abstract: PURPOSE:To keep the one of a center frequency and a sharpness to be a constant value with making the other of them variable by providing a frequency adjustment circuit and a sharpness adjustment circuit. CONSTITUTION:An input signal s1 is outputted from a buffer circuit 7 through amplification circuits 2, 3 and 4. When the current I0 of the variable constant- current source 23 of the frequency adjustment circuit 21 is made to be varied, the mutual conductance of the amplification circuits 214 alters keeping a specified ratio and the oscillation characteristic of the output signal 52 is emphasized(or supressed) by the value expressed as the sharpness Q, which is kept constant while the center frequency f0 alters. On the other hand, if the voltage V4 of the variable voltage source 31 of the sharpness adjustment circuit 22 is made to be varied, only mutual conductance of the amplification circuit 2 alters and the sharpness Q separately alters, while the center frequency f0 is kept to be the constant value.

Abstract: PURPOSE:To improve the workability of the title system by setting two kinds of maximum mouse moving extents corresponding to the displaying extent of a display device and, at the same time, making switching between the two extents easier. CONSTITUTION:The maximum moving extent of a mouse 12 corresponding to the displaying area of the display device 13 is decided by two-point moving the mouse 12 at the time of initialization and the maximum moving extent of the mouse 12 is, for example, reduced by designating a change in the maximum moving extent by means of a designating means 12a at the time of using the mouse 12. When the mouse 12 is moved in such state, coordinate transformation takes place so that the coordinate data produced when the mouse 12 is moved can become coincident with the coordinate data produced when the mouse 12 is moved in the initial maximum moving extent. Therefore, the movable extent of a designated point on the screen of display device can be prevented from changing.

Abstract: PROBLEM TO BE SOLVED: To improve withstand voltage performance without lengthening leg parts by forming auxiliary wall parts to cover a part where an electric insulating material- made hollow cover main body divided in the circumferential direction and the electric insulating material-made leg parts extending outward in the radial direction from the vicinity of both end parts divided in its circumferential direction, continue with each other or a part more than that. SOLUTION: Auxiliary wall parts 17 and 18 to cover a part where respective leg parts 15 and 16 extending outward by continuing with circumferential directional both end parts 13 and 14 where an almost cylindrical cover main body 12 overlaps in the radial direction by being divided in the circumferential direction continues with the cover main body 12, are desirably formed in a streamline shape and an almost cylindrical shape having small air resistance. Divided tip parts 23 of loose end parts 22 continuing with base parts 21 of the auxiliary wall parts 17 and 18 have a prescribed interval between tip parts 24 of inserting guide parts 19 and 20 of the respective leg parts 15 and 16. It is better to interpose a space layer between the auxiliary wall parts 17 and 18, the cover main body 12 and the respective leg parts 15 and 16.  Since the respective leg parts 15 and 16 can be shortened by improving withstand voltage performance, vibration of an electric wire by wind is reduced, and rupture by metal fatigue can be prevented.

IPC: H01L49/02
Filed: 1985-09-11
Abstract: PURPOSE:To enable a chemically stable hard film to be formed in a given pattern with excellent adherence as an abrasion-resistant layer by forming a metallic film layer on an area other than a heating section in a protection layer and after the formation of the hard film, creating the abrasion-resistant layer on the heating section of the protection layer following the removal of the metallic layer and metallic film layer. CONSTITUTION:A Ni film 9 is formed in the thickness of about 0.5mum on the entire surface of a protection layer using sputtering technique. Next, that part of the Ni film 9 which represents a heating section is removed with the help of photoetching. After this process, a Ni plated layer 10 of an about 4mum thickness is formed through non-electrolytic plating on the remaining Ni film 9. Later, a Si3N4-based abrasion-resistant layer 8 having a thickness of about 2mum is formed as a chemically stable and highly conductive hard film. Finally, this whole substrate is soaked in nitric acid and further, is subjected to ultrasound treatment. This results in the melting and removal of the Ni plated layer 10 and Ni film 9 and the formation of an abrasion-resistant layer 8 only on the heating section of the protection layer.

Abstract: PURPOSE:To enlarge the utilization range of a power supply voltage by combining a first comparator having a PNP input stage and a second comparator having an NPN input stage, and connecting an NPN type active element and a PNP type active element to an output of the former and an output of the latter, respectively. CONSTITUTION:When a power source VCC is applied, an output of a second comparator 12 becomes a low level, a first transistor Q1 is turned on, and an output terminal TOUT becomes high. However,an output of 11 is a low level and a second transistor Q2 remains turned off. Therefore, a capacitor C1 is charged through a fourth resistor R4, and when its charging voltage exceeds a prescribed value, outputs of 11 and 12 become a high level and Q2 is tuned on, and Q1 is tuned off. As a result, C1 starts to discharge through R4, and when a voltage of C1 drops to a value determined in advance, the outputs of 11 and 12 are varied to a low level, respectively. In such a way, in an output terminal TOUT an oscillation output of a frequency determined by the capacity of C1 and a resistance value of R4 is obtained.
