Title: Negative pressure control device for brake booster
Inventor: MIZUTANI KYOJI
IPC: F02D9/02
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To secure required braking force even if the braking performance of a brake device is lowered by providing a fade determining means to control the negative pressure of a brake booster to a designated target value when the fade state is determined. SOLUTION: A brake ECU 60 judges lowering of a fluid level in a reservoir tank 51, abnormality of a hydraulic pump 58a and abnormality of a brake booster 41 in addition to lowering of booster negative pressure over a designated value. When it is judged that the braking performance of a hydraulic brake device 58 is lowered by occurrence of fade, a negative pressure generating request signal is given. The engine ECU 12 conducts booster negative pressure control for a designated negative pressure generating request value in response to the signal. Thus, even if the braking performance of the hydraulic brake device 58 is lowered, required braking force can be secured by assisting of the brake booster 44.

Abstract: PROBLEM TO BE SOLVED: To form a proper taper-shaped side surface and to eliminate the formation of a gap, when filling a groove by combining NF3 and HBr and performing plasma etching when forming the taper-shaped opening in a silicon substrate. SOLUTION: A dielectric layer and a hard mask 16 for covering the dielectric layer are formed on the upper surface of a silicon substrate 14, and an opening for exposing one portion of the ground silicon substrate 14 is formed. Then, the silicon substrate 14 is arranged in the process chamber of a plasma-etching device. Then, a taper-shaped opening 18 is etched to the part of the silicon substrate 14, that is not covered with the hard mask 16 by a plasma which is generated by NF3 and HBr input gases, thus obtaining an improved etching speed and an improved controllability for the tapered side surface. Therefore, by forming the improved tapered side surface, the formation of a gap when filling a groove is eliminated.

Title: Storage battery with protection device
Inventor: YUCHI ISAO
IPC: H01M2/34
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To protect a storage battery and its load side by immediately cutting current supply even in such a case where the circuit is in abnormal condition on the storage battery side, for example, generation of short-circuiting between terminals as well as enabling to respond to any circuit abnormality on the load side by providing such a protection device as having a function to cut off any excessive current, in a position closest to the power supply source (current source terminal). SOLUTION: When a fuse 11 is used as protection device, the fuse is assembled in a current terminal 10 in such a state as being able to be replaced when blow out. In this way, even if the place of generation of such a trouble as the cause of excessive current is either on load side or on the storage battery side, the fuse makes its action certainly so that any apparatus and storage battery connected to the load side can be protected. Particularly, when storage batteries are placed in serial connection, since each storage battery is provided with its own protecting device, even in the worst case, damage on only one piece of the storage batteries can cover the whole situation satisfactorily. Thus, any expansion of damage can be prevented.

Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To make pitting corrosion be hardly brought about, by providing a Zn-Al pseudo-alloy layer of which the Al content is a specified value, a water-based coating film layer of which the water absorption is a specified value and further a solvent coating film on a steel pipe. SOLUTION: By this method for corrosion-proof coating of a steel pipe, a Zn-Al pseudo-alloy layer which is provided as a primer layer showing an effect of cathodic protection and of which the Al content is 15-50 wt.%, then a water-based coating film layer which is provided for improving the effect of the cathodic protection of the primer layer and of which the water absorption is 5-50% and lastly a solvent coating film which is provided for intercepting water in the water-based coating film layer from the water in an environment, lessening the lowering of the effect of the cathodic protection due to the provision of the water-based coating film and also protecting the steel pipe from an impact or the like from outside, are provided on the steel pipe.  When the Al content is in the range of 15-50 wt.%, the effect of the cathodic protection being more excellent than that of a Zn layer is shown. In the case when the water absorption of the water-based coating film layer is less than 5%, the effect of the cathodic protection is not seen nearly at all, and when it exceeds 50%, the coating film has a bloating tendency, which is undesirable for durability, though the effect of the cathodic protection is shown.

IPC: G01B11/06
Filed: 1982-05-01
Abstract: PURPOSE:To measure the thickness of a sheet-like object, by detecting the high or low intensity of the light owing to interference that appears in the monochromatic light divided from the transmitted light when double color light is irradiated to said object as a function of the wavelength. CONSTITUTION:The light transmitted through a film 6 is divided by a prism 14, and each element of a photosensor 15 is arrayed on the color band forming surface thereof; therefore, the intensity of each monochromatic light is detected by the predetermined element. When each monochromatic light is transmitted through the film 6, the light is partly reflected by the front and rear surface of the film 6, and the transmittance thereof is changed by the interference phenomenon of the reflected light and the rectilinear light. If the wavelengths forming the adjacent crest and crest of each monochromatic light obtd. by scanning the photosensor 15 installed on the color band forming surface are defined as lambda1 and lambda2, the relation l=(1/2ncostheta).[1/(1/lambda1-1/lambda2)] holds, and if the refractive index (n) of the film and the incident angle theta of the light are beforehand determined, the thickness l of the film 6 is determined continuously from the output E2 of an arithmetic part 17 by inputting of the scan signal E1 of the photosensor 15.

Filed: 1987-03-27
Abstract: PURPOSE:To make it possible to form an excellent contact using a simple means by a method wherein, when an impurity diffusion layer is formed, both a shallow impurity implantation and a deep impurity implantation are performed in a superposing manner. CONSTITUTION:A metal is selectively buried in a contact hole 3, having a high density impurity layer on which the distribution of impurity density is made uniform by introducing impurities at least twice or more on a semiconductor 1, by reacting the gas containing metal. Accordingly, the high density section of impurity profile can be made uniform. As a result, the increase or the irregularity in contact resistance can be prevented even when the depth of the contact position between a double film 5 and an impurity diffusion layer 4, for example, is uneven.
