Title: Vertical drain pipe fitting
Inventor: KOJIMA NORIATSU
IPC: F16L41/02
Filed: 1989-12-01
Abstract: PURPOSE:To decelerate drainage falling speed, perform ventilating action effectively and minimize pressure fluctuation in a pipe by providing the wall surface of a drain passage with a protruding part formed in the state of biting inward from the inner diameter of a pipe end connection. CONSTITUTION:Drainage falling down in a vertical drain pipe fitting falls in an expanded part 3 while keeping a ventilation zone mainly around the center in the pipe. A part of the drainage flows down directly into a vertical drain pipe below, and another part collides against the upper face of a protruding part 11 formed in a drain passage 9 provided between the expanded part 3 and a lower vertical pipe end connection and falls being decelerated by the resisting action. At this time, the drainage colliding against the protruding part 11 flows down being scattered in such a way as to close the cross section, at the protruding part 11, of the drain passage 9. However, as a diameter enlarged part 12 performs by-pass action at the same time, ventilation is communicated vertically through this part. The drainage falling speed is therefore decelerated by using this vertical drain pipe fitting inspite of its simple structure, as well as ventilating action can be performed effectively.

Title: Manufacture of lead-acid battery
Inventor: KARASAWA SHOJI
IPC: H01M50/529
Filed: 1988-12-12
Abstract: PURPOSE:To prolong the life and enhance the anti-vibration property by forming fixing boses, for supporting elements firmly, on the inner wall of each cell in a battery jar by means of injection molding of plastics in a consolidated structure, and thereby securing the adhesion of the grating with active substance while elongation of the grating is suppressed. CONSTITUTION:Fixing bosses 7 supporting firmly elements 4, equipped with neg. elect. plate and pos. elect. plate, on the inner wall of each cell 3 are formed consolidated by means of injection molding of plastic, wherein the elements 4 are to be inserted into the cells 3 in the battery jar 1 made of plastics, which is partitioned into a plurality of cells 3 by partition walls 2. These bosses 7 are located where parts of a strap besides its inter-cell connection part are supported firmly. Accordingly the elements 4 can be fixed sturdily by the fixing bosses 7, that will prevent shortcircuiting between electrode plates and slipping- off of the active substance due to elongation of the electrode plate grating of element 4 under high temp. environment. Thus anti-vibration property in high degree and a long life will be achieved.

The thickness of the alumite layer is specified to <=0.5 mum and the difference between the cell diameter Dc and the pore diameter Dp to >=250Angstrom . The magnetic ..path length between the adjacent magnetic layers is, therefore, increased and the spacing loss at the time of reproduction is lessened by taking the difference between the cell diameter Dc and the pore diameter Dp as wide as possible. The perpendicular magnetic recording medium having the excellent high-density recordability is obtd. in this way.

Title: Ultrasonic diagnostic apparatus
Inventor: TOSEN TAKAO
IPC: A61B8/00
Filed: 1987-12-11
Abstract: PURPOSE:To achieve cost reduction and to suppress the generation of heat, by making the waveform of a signal for simultaneously driving vibrators variable to bring the same to a weighted signal. CONSTITUTION:A pulse generator 12 forms a drive pulse P1 having three bursts on the basis of the high frequency signal from a high frequency oscillator to input the same to a number-of-burst controller 13 and forms three drive pulses P21, P22, P23 equal in amplitude but respectively having one, two and three bursts. On the basis of these pulses, a transmission beam former 14 forms not only a drive pulse 33 but also a drive pulse P32 delayed by DELTAt and a drive pulse P31 delayed by 2.DELTAt. Then, the pulses P33, P32 and P31 are respectively outputted to a transmission driver 16c, transmission drivers 16b, 16d and transmission drivers 16a, 16e. That is, as the number of bursts increase, the amplitude of an outputted sonic wave becomes large with the increase in the number of said waves and the output of the sonic wave at the center of an aperture becomes large equivalently. Therefore, a high voltage control driver circuit becomes unnecessary at every transmission driver and cost reduction can be realized and the generation of heat can be suppressed.

Title: Mechanism for preventing irregular winding for magnetic tape device
Inventor: UKAI HIRATAKA
IPC: G03B1/04
Filed: 1991-11-28
Abstract: PURPOSE:To prevent damage to a tape and the irregular winding of a reel by guiding the edge of one side of a tape and pressing the edge vicinity of the other side of the tape by a back arm roller. CONSTITUTION:Since the edge vicinity of the upper side of a tape 22 is pressed by a back arm roller 31, when the tape 22 is wound round a winding reel 23, involved air is released from the lower side of the tape 22. Also, since the tape 22 is inhibited from moving downward by the lower side flange 28 the tape 22 is stably wound even though the pressing force of a back arm roller 29 is not large and the irregular winding around the reel is prevented. Further, although the back arm roller 31 is used for pressing the upper part of the tape 22 while a second roller guide 25 guides the lower edge of the tape 22 by a lower side flange 28 in this constitution, conversely the lower side of the tape may be pressed by the roller 31 while the flange 28 is energized by a spring and the fixed flange 27 of an upper side guides the edge of the upper side of the tape 22.

Filed: 1987-12-15
Abstract: PURPOSE:To execute an automatic setting to an optimum channel by causing the channel of the output signal of an RF modulator to be variable according to the decision result of an output signal channel deciding means by means of a frequency synthesizer. CONSTITUTION:An existing signal detecting means detects the channel of an existing signal in a broadcasting signal searched by a broadcasting channel searching means, and outputs it to an output signal channel deciding means. The output signal channel deciding means selects and decides the output signal channel of an RF modulator 9, and outputs the decision result to an output channel selection setting means. The output channel selection setting means causes the output signal channel of the RF modulator 9 to be variable, and sets it to a decided channel. Namely, by a microcomputer 7 for a frequency synthesizer turning, the output channel of the RF modulator 9 can be automatically set to the channel not to interfere the broadcasting channel.

IPC: G06F3/023
Filed: 1988-12-14
Abstract: PURPOSE:To enable a user to perform conversion into a desired code without searching and depressing a key again based on a mode conversion range and the instruction information on the mode conversion by storing previously the codes inputted via keys and the codes allocated to each key. CONSTITUTION:In the case a user inputs 'TONTOKAIMO' by mistake instead of 'system' due to a KATAKANA (square form of Japanese syllabary) lock key kept turned on, the user pushes a cusor key ( ) displayed at a place following 'MO' by 6 times to designate a range of the mode conversion. Thus a cursor is sent back to 'TO' of 'TONTOKAIMO'. Then 'SYSTEM' is displayed with push of a conversion key, and the desired 'system' is displayed with the second depression of the conversion key. In such a manner, the user can perform the conversion into a desired code.
