Title: Signal level detecting circuit
Inventor: SHIMIZU YOSHIO
IPC: G01R19/165
Filed: 1989-02-01
Abstract: PURPOSE:To detect the level of an input analog signal with high accuracy and in a comparatively simple constitution without using an A/D converter of many bits by preparing a level comparing part, a control signal producing part, an integrating part, etc. CONSTITUTION:An external control signal Sc is supplied to the comparison input terminal of a level comparing part 31 from an input terminal 33. Then the level of the signal Sc is compared with the level of an integration output signal Sw given from an integration circuit 29. Thus a comparison output signal Po is outputted. The signal Po is supplied to a counter 17 of a control signal producing part 11 via a terminal 4, and a 1st control signal Pxu or a 2nd control signal Pxd is outputted via a count value deciding part 19 together with the clock signal received from a clock generating part 15. In this case, the signal Pxu is obtained with the rise of the level of the signal Sc. While the signal Pxd is obtained with the fall of the level of the signal Sc. Then the level of the signal Sc is detected in many steps as the output signals of the part 11 via a pulse signal generating part 13. Thus the level of an input signal can be detected with high accuracy and in a comparatively simple constitution.

Title: Hot water supplying apparatus
Inventor: TSURUTA KUNIHIRO
IPC: F24H1/18
Filed: 1984-02-10
Abstract: PURPOSE:To prevent base material from dissolving and contrive to avoid developing insoluble blue water or slightly opaque precipitate by a method wherein metallic sacrificial anode, the ionization tendency of which is larger than that of the base material of a heat exchanger, is connected to the exchanger and at the same time the anode is covered by a heat- and water- resisting aggregate with a slit. CONSTITUTION:For an example of application, a copper or copper alloy heat exchanger 3 and a sacrificial anode 10, the ionization tendency of which is larger than that of copper, are electrically connected with each other through a lead wire 11 and a metallic body 11'. In addition, the sacrificial anode 10 is covered by a heat- and water-resisting aggregate 13 with a slit 12. Accordingly, the dissolution of the base material metal of the heat exchanger 3 is suppressed and even the dissolution of the sacrificial anode metal is done by the movement of its metal ions only through the slit 12 of the aggregate 13, resulting in suppressing the diffusion of the metal ions. Further, because the anode 10 is covered by the aggregate 13 with the slit 12, the precipitate developed by the dissolution of the sacrificial anode metal accumulates on the inner surface of the aggregate 13, resulting in suppressing its accumulation in a hot water storage tank or feed water piping. Thus, no development of blue water due to the adhesion of insoluble substance or of slightly opaque precipitate, which is apt to develop in aluminum heat exchanger.

Title: Semiconductor device
Inventor: NOJIRI KAZUO
IPC: H01L21/60
Filed: 1982-02-19
Abstract: PURPOSE:To prevent the erosion of a pad caused by solving of P, by a method wherein the pad is formed at spacing within an opening of PSG being fluidizable, and PSG of low P concentration is formed. CONSTITUTION:PSG layer 3 with P concentration of 3-5mol%, SiO2 4 without addition, and PSG layer 5 with P concentration of 10-12mol% are laminated to SiO2 film 2 on Si substrate 1. Al pad 7 is formed on SiO2 4 within an opening 6 of the layer 5 and separated from the layer 5. The Al pad 7 is selectively covered by CVD SiO2 8 and line junction is formed on the exposed pad 7. Since the layer 5 and the pad are separated, moisture entered from outside does not easily act on the layer 5. Even if phosphoric acid is liberated from the layer 5, degree of erosion of the pad 7 is significantly decreased. The layer 5 has P of high concentration for melting but upper limit of 12mol% is preferable so that water absorbing property is not increased beyond necessity. The layer 3 with P concentration of 3mol% or more is preferable in order to prevent contamination of the layer 2 through a gap 9 between the pad 7 and the layer 5.
