Title: Guide post for magnetic tape
Inventor: SAKURAI YASUO
IPC: G11B15/60
Filed: 1982-09-03
Abstract: PURPOSE:To run stably a tape and to improve the sound quality and image quality of a VTR, by using a guide post produced by coating the fixing part between a barlike tape sliding part of a stainless steel and a base with an attenuation part of a resin material. CONSTITUTION:A guide post is constituted of a barlike tape sliding part 22 of a stainless steel having 3mm. diameter and an attenuation part 23 covering the outside circumference in the press fitting and fixing part of the base 2. The part 23 consists of a plyamide resin and has a strong viscosity attenuating characteristic. Strain is generated in the part 23 by the bending vibration of the guide post but the vibration damping force acts in the direction of hampering the vibration of the post by the viscosity resistance thereof, thereby suppressing the self-vibration. The self-vibration between the tape and the post is thus suppressed and the external vibration to be transmitted to the tape is averted, whereby the tape is run stably and the sound quality and image quality of a VTR are improved.

Title: Tap-controlled gas hot-water supplier
Inventor: YOKOAJIRO YOSHIYUKI
IPC: F23N5/18
Filed: 1984-07-25
Abstract: PURPOSE:To obtain the tap-controlled gas hot-water supplier which is capable of controlling an excessive temperature fluctuation, is which causes no errorneous operation and which keeps a stabilized hot-water temperature, by a method wherein a proportional control valve is driven by a signal which is the sum of outputs of a heat amount operator and a differential corrector. CONSTITUTION:The frequency signal of a water amount detector 3 is introduced into a water amount operator 8 to obtain a water amount signal proportional to the amount of water. When the amount of water is changed suddenly, a differentiator 9 generates an output (b). The differential corrector 10 generates an output signal (c) with a time interval (n). The output (c) is added to the output of the heat amount operator 7 and the amount of combustion becomes smaller than the operated value (e) of the amount of combustion by the hatched portion (d) in the diagram whereby the excessive fluctuation (f) of feed hot-water temperature is controlled to become smaller than the value of fluctuation (g) when no correction is made. In case noise or the pulse of the water amount detector is absent, the water amount signal becomes a single pulse signal as shown by (h). As a result, the differential value (i) at every constant sampling time becomes continuously generated signal of different polarity. Accordingly, the differential corrector 10 will never output the differential signal of output (j). According to this method, the amount of combustion (k) is not affected by a noise signal and therefore, hot-water temperature fluctuation will never take place.

CONSTITUTION:N<+> type buried regions 2 and P type buried regions 3 are formed in the active element forming region of a P type substrate 1 and after an epitaxial layer 4 is formed on the P type substrate 1, an SiO2 film 5 and an Si3N4 film 6 are formed on the epitaxial layer 4. An etching is performed on parts of the epitaxial layer 4, which are respectively to be used as the isolation forming region, using parts of a photoresist film 7 as masks and grooves 8 are formed. Furthermore, ions, such as ions of H<+>, He<+>, Ar<+> and O<+>, are implanted in the grooves 8 using the parts of the photoresist film 7 as masks and damaged regions 20 are formed. Then, an SiO2 film 9 and an Si3N4 film 10 are formed on each of the side faces of the grooves 8. When an oxidation is performed in high-pressure steam, the oxidation progresses from the bottom parts of the grooves 8, from where the epitaxial layer 4 is exposing, the epitaxial layer 4 is consumed, SiO2 films 11 are formed and the grooves are filled. In this case, arsenic in the N<+> type buried regions 2 and boron in the P type buried regions 3 are diffused, and an N<+> type region 21 and a P type region 22 are formed just under each SiO2 film 11. Then, the Si3N4 films 6 and 9 are removed, and a P<+> type base region 13 and a P<+> type base region 14 are formed.
