Title: Magnetic head
Inventor: TSUNODA MASATOSHI
IPC: G11B5/60
Filed: 1978-03-24
Abstract: PURPOSE: To suppress damaging of recording media and enable sure reproduction to be performed by letting the contact face of the magnetic head of a flexible disc apparatus be a cylindrical face in the sliding direction and disposing a reproduction core gap near the vertex of the  cylindrical face.  
     CONSTITUTION: The contact face of a magentic head composed of a slider 4 buried with a  recording-reproducing core 8 with a rotating flexible magnetic recording medium 1 is formed in  the cylindrical face form wherein the sliding face 14A is made nearly linear in the section rectangular to the sliding direction and the sliding face 14B is made curve of a radius of curvature  R 1  in the section in the sliding direction. In addition, a small curvature R 2  is given to the chamferred parts 11A thru 11D between the contact face and the circumferential edge part and the  gap 16 of the reproducing core 8 is disposed near the vertex 15 of the abovementioned cylindrical  face. Hence, even if the posture of the slider 4 makes minor change, the portion having the  curvature of R 2  contacts the medium 1 and therefore the medium 1 is not damaged; moreover  the gap 16 of the core 8 exists in the vertex portion of the cylindrical face and therefore the  spacing fluctuations from the mdium 1 are slight and the adverse influence to the reproduction is  averted. The value of the abovementioned R 1  is preferably 3 to 20m.

Title: Magnetic disc memory device
Inventor: SUZUKI KUNIO
IPC: G06F3/06
Filed: 1980-03-19
Abstract: PURPOSE:To give an automatic backup function to a computer, by writing in the data from the computer to two sets of discs at the same time at a disc control circuit and automatically making disc drive switching at an abnormal data readout. CONSTITUTION:The track No and readout instruction designated from the computer 1 are set to the register 20-1 to start the detection of the sector. Further, when the sector is detected, the data is stored in the memory 12 after that. Thus, the data from the computer 1 is written in two sets of discs at the disc control circuit 2. In this case, if one disc is inoperative due to mains failure, the state is reflexed to the disc ready signal 30-1, the processor 5 reads out the state from the register 31 to automatically switch the operation so that the data readout is made from another disc automatically. Thus, the load of the computer is halved and the automatic backup function is given to the computer.

After n-type source regions 3 are formed using this PSG film as a diffusion source, an oxide film 14 is selectively formed by a plasma CVD method and a polysilicon film 8 for resistance is applied on the film 14.  After the film 8 is selectively removed, an oxide film 9 is selectively formed and an emitter electrode 10 is formed of an Al-Si film on the film 9.

Abstract: PROBLEM TO BE SOLVED: To increase degrees of freedom of a shape of a gas generator by controlling an appearance timing of an opening and tearing means in accordance with a form of collision and a build of an occupant and ignition timing in an inflation chamber when an air bag is developed so as to control a release speed of gas. SOLUTION: Internal pressure in an inflation chamber 4 is changed and an area of opening of a rupture plate 2 is changed when flammable gas and an ignition source 3 are provided in the inflation chamber 4 and the rupture plate 2 in the inflation chamber 4 is ruptured by an opening and tearing means 5 so as to control flow-out speed of gas. That is, internal pressure in the inflation chamber 4 is increased and the area of opening of the rupture plate 2 is decreased when the rupture plate 2 in the inflation chamber 4 is opened and ruptured by igniting the inflation chamber 4 and the opening and tearing means 5 almost simultaneously, thereby reducing flow-out speed of gas. Consequently, it is possible to increase degrees of freedom of a shape of a gas generator and simplify the inner structure thereof.

Title: Forming method of pattern of metallic film
Inventor: OKUMURA KATSUYA
IPC: C23F1/00
Filed: 1980-03-19
Abstract: PURPOSE:To enable forming of metallic film pattern with ultra-thin 2-layer structure by using the notable difference in etching speed between the Al film accumulated near the step and other Al coated parts. CONSTITUTION:After forming an SiO2 film 3 and a contact hole 4 on an Si substrate 2 with a diffusion layer 1, a steep step 6 is formed on the film using a resist 5. The thin polycrystal line film 7 is accumulated on substrate 2 covering the step 6. Then, Al film 8 is accumulated all over. The part of Al film 8a near the step 6 will be of considerably low density and quality, compared with other parts of Al  film. Then, by etching the whole film, the part of the film 8a near the step 6 is  preferentially and locally removed by a small width, thus forming Al pattern 9.  Then the film 7 is etched using the pattern 9 as a mask, and polycrystalline Si  pattern 10 is formed. Thus, from pattern 9 and 10, ultra- thin metallic film pattern  10 is formed.

Abstract: PURPOSE:To allow the efficient execution of the defect inspection of a light shielding region by forming a pattern for regulating the min. required light shielding range in the light shielding region. CONSTITUTION:The pattern 4 for regulating the range of the min. required light shielding region 3A in order to prevent the leakage of light from the outer periphery of the pattern region including a circuit pattern region 1 and a scribing line region 2 when subjected to step exposing by a stepper is plotted in addition to the circuit pattern region 1 and the scribing line region 2 at the time of plotting the patterns by using an electron beam plotting device on a mask substrate formed with a positive type electron beam resist. The reticule is then completed by ordinary processing treatments. The inspection of only the inner side of the pattern 4 for regulating the light shielding range is, therefore, necessitated at the time of inspecting the defects of the light shielding region 3.

Abstract: PURPOSE:To provide an automatic operation device for a ventilation fan for a bathroom capable of performing a sufficient drying of the bathroom by a method wherein the ventilation fan is operated at the most preferable time corresponding to a condensation state. CONSTITUTION:In case of operation of a ventilation fan for a bathroom, a condensation sensing signal is inputted from a condensation sensor input circuit 21 into an operation time calculation means 25. The operation time calculating means 25 may multiply a condensation sensing time by 25 times during operation of the ventilation fan, for example, a lower limit value is set to 30min and an upper limit value is set to 180min, respectively, to calculate an operating time. The ventilation fan control circuit 20 is controlled by an operation stopping means 27 in such a manner as the ventilation fan is stopped as the actual operating time of the ventilation fan is reached to the calculated operating time. Since the ventilation fan is operated on the basis of the sensing time of the condensation, an occurrence of mildew or damage of the wall surface of the bathroom can effectively be prevented.
