Filed: 1987-12-15
Abstract: PURPOSE:To surely and rapidly adjust the concn. of Al and to improve productivity by providing an enclosing part to the surface part of a plating bath and adding an Al removing agent into this section, then stirring the bath. CONSTITUTION:The enclosing part 4 consisting of a frame body 3 is provided to the surface part of the zinc plating bath 2 of a device for guiding a steel strip 1 to the plating bath 2 and plating the steel strip continuously. The Al removing agent 6 is added from a manhole 5 to the bath 2 in this section and the bath 2 is stirred by an impeller 2 to diffuse the agent into the bath 2, thereby bringing the agent into reaction with the Al in the bath and removing the Al. The fumes generated at this time are sucked by a suction blower 8 and are introduced into a cleaning device 9 where the fumes are neutralized to the pollution-free fumes. These fumes are released into the atm. The removal of the Al is continued by adding the Al removing agent to the bath until the target concn. of the Al is attained and the low Al bath is obtd. The concn. is adjusted by adding the Al to the bath 2 in the case of preparing the high Al bath. The downtime for the purpose of adjusting the bath is averted by this method.

Filed: 1988-12-14
Abstract: PURPOSE:To improve a guard ring in breakdown strength and to make a dark current small by a method wherein the depth of the peripheral junction of a photodetective region is made smaller than that of the central junction, and the depth of the junction of the guard ring is made larger than that of the peripheral junction of the photodetective region. CONSTITUTION:The peripheral part of a photodetective region 19 is located outside the inner circumference of a ring-like semiconductor spacer layer 17, the depth of the peripheral junction of the photodetective region 19 is made smaller than that of the central junction, and the depth of the junction of a guard ring 18 is made larger than that of the peripheral junction of the photodetective region 19. That is, the depth of the peripheral junction of a steeply sloping pn junction can be smaller than that of the central junction by nearly the thickness of the spacer layer 17, therefore a sufficient guard ring effect can be obtained without using the deep guard ring 18, keeping the surface of a semiconductor multilayer film flat. By this setup, not only a guard ring can be improved in breakdown strength but also a dark current can be reduced.

Title: Magnetic picture-recording and reproducing device
Inventor: KAWAGOE SHOJI
IPC: G11B5/02
Filed: 1987-12-16
Abstract: PURPOSE:To execute a voice post-recording to use an FM sound signal by recording a time-base-compressed sound signal in the shallow layer of a magnetic layer of a part in which the recording track of a rotary head is overlapped on a linear sound track. CONSTITUTION:For a magnetic tape 7, a winding angle is made larger than 180 deg. so that rotary video heads 10 and 11 can overlap a linear sound track 18. In the overlapping part, the sound signal by a fixed head 15 is recorded in the deep layer part of the magnetic layer, and the sound signal time-base- compressed by using the rotary head 10 is recorded in the shallow layer part. Consequently, on the shallow layer of the overlapping part, the sound signal can be recorded independently of a video signal, and moreover, such a sound signal can be recorded with a high density by the rotary head 10. Thus, the post-recording of the voice with a sound quality higher than the voice post- recording of the fixed head 15 can be executed.

Title: Picture processing ic
Inventor: TAKEDA TOMOYUKI
IPC: H04N1/40
Filed: 1989-12-07
Abstract: PURPOSE:To effectively utilize picture information outputted from a CCD by skipping a dummy picture data bit outputted from the CCD. CONSTITUTION:A picture data includes a dummy bit (such as 64 bits) outputted from a CCD 111. For example, '64' is preset to a counter 124 by a CPU 14 corresponding to the bit number 64-bit of the dummy bit. Thus, while the first 64-bit of the output of the CCD 111 is inputted to a picture processing section 123, the counter 124 does not generate a clock 140. Thus, the memory capacity storing the picture information outputted from the CCD is saved and only the picture information excluding the dummy bit is used to apply picture processing.

Title: Bellows container controlling contraction of bellows
Inventor: MATSUDA MASAYOSHI
IPC: B65D21/08
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive bellows container which can naturally retain the contents while keeping the volume of the using container to become substantially almost the same with the volume of the rest of the contents. SOLUTION: The contraction action of a bellows is freely controlled in a bellows container which can retain the contracted shape and which is provided with a circular dint 7 at the upper wall part 4 or the lower wall part 5 of the bellows 8. The dint 7 reduces the deforming resistance of the wall and concentratively absorbs the compressive energy or the suction energy against the container 10 to differentially start to lead it in the bellows or lead it out of the bellows and closely stick the wall to the other wall side. By this action, a necessary compressive force or a suction force is lessened in comparison with the conventional cases and further, the wall of contraction side can be selected. And the folding direction of the bellows can be standardized by the selectivity.  Moreover, a selective control of the contractive order of the bellows can be realized by the selective control of the size of respective dents.

IPC: F04B49/10
Filed: 1999-11-08
Abstract: PROBLEM TO BE SOLVED: To provide a temperature indicator which gives an easy-to-observe visual indication of whether or not fluid which is stored in a container or flowing in a conduit exceeds a specific temperature. SOLUTION: The temperature indicator 10 intrudes into the fluid flow in the conduit by penetrating an opening part. The temperature indicator is equipped with a housing 12 which substantially surrounds an internal chamber 14 and is fitted at least partially in an internal hole 16 extending from the internal chamber to the external surface of the housing to apply an energizing force between the housing and indicator member, thereby pressing an indicator member against the internal hole. An adhesive adheres the indicator member and housing together and then stops the indicator member from moving toward the internal hole through the operation of the energizing member. The adhesive is thermally sensitive and substantially releases the indicator member and housing from being adhered together when the temperature of the adhesive substantially reaches specific temperature.

Abstract: PURPOSE:To obtain a desired antenna gain without deteriorating the S/N by synthesizing signals from plural radiation parts via active elements, supplying the result to a feeding part and supplying a DC voltage to the active elements via the feeding part. CONSTITUTION:Signals from plural radiation parts are synthesized respectively via active elements 20 and the result is supplied to a feeding part 10 and the gain of the active element 20 is increased by taking a loss in a feeder 9 located on its halfway into account. Thus, the desired antenna gain is obtained in the feeding part 10 and the effect of thermal noise, etc., of the feeder 9 on its way is not susceptible, then the S/N of the feeder part 10 is not deteriorated. Moreover, a DC voltage is supplied respectively to the active elements 20 via the feeder part 10. Since the DC voltage (bias voltage) is supplied substantially via the feeder 9, it is not required to provide a separate bias pattern and the deterioration in the antenna performance due to the mutual interference between the bias pattern and the antenna pattern is prevented.
