Title: Protecting circuit of amplifying device
Inventor: OOTSUKI TAKASHI
IPC: H03F1/42
Filed: 1982-09-20
Abstract: PURPOSE:To protect an amplifying device and a loudspeaker when a ground- fault is generated, by providing a control circuit for cutting off an electric power source side driving transistor (TR) of one SEPP amplifying circuit in case when ground-fault of an output terminal of its amplifying circuit, and also giving an electric current for making a ground side driving TR of the other SEPP amplifying circuit conduct. CONSTITUTION:When an output terminal 10 becomes a ground level, TRs T1, T3 are turned on, the base potential of TRs T4, T5 is raised, and they are made to conduct. As a result, an electric current from a constant-current circuit connected to idling circuits I1, I2 flows through the TRs T4, T5, and the potential of terminals 13, 23 drops. A TRQ15 is turned off, accordingly, a TRQ17 is also turned off, and its breakdown can be prevented. On the other hand, as the potential of the terminal 23 drops, a TRQ24 is turned on, and a TRQ25 is also turned on, therefore, an output terminal 20 becomes a ground level. In this way, both terminals of a loudspeaker SP become almost equal potential and the loudspeaker SP is protected.

Title: Radiation detector
Inventor: KURISUTOFUAA SUTANRII KURANSUT
IPC: H01L31/0203
Filed: 1990-06-29
Abstract: PURPOSE: To detect β ray using a photodiode by allowing rays to pass through a thin-film surface and arranging a device for detecting ionization rays from external rays in relation with an enclosure. CONSTITUTION: A photodiode 1 is placed in an enclosure formed by a substrate 3 and a case 5. The case 5 has a thin-film wall surface 7. The thin-film surface 7 enables rays to pass and at the same time, gives environmental isolation to the photodiode 1, thus preventing light from entering the photodiode 1. The enclosure limits a volume 11 that is filled with an inactive gas, for example nitrogen, to prevent the photodiode 1 from being damaged. A wire net 15 is added above and/or below the thin-film surface 7 as a structural support or as an microphone operation to the thin-film surface 7, more specifically for reducing acoustic stimulus, thus eliminating the need for a high-voltage power supply and enabling a detector to be suited for the β ray dosimeter with a small battery feed.

Abstract: PURPOSE:To a simplify constitution by using by 1st and 2nd RAMs, 1st and 2nd counters, a selector, 1st and 2nd address extraction sections and a control section so as to convert the data transfer speed and the transfer sequence simultaneously. CONSTITUTION:The 1st and 2nd counters 1, 2 count clocks CK1, CK2 respectively, the selectors 11-14 selects the count of the 1st counter 1 as a readout address of a prescribed sequence, selects the count of the 2nd counter 2 as a white address of a different order and output the result to the 1st and 2nd RAMs 3, 4 alternatety while being switched. Based on the 2nd and 1st address extraction sections 22a, 22b, 21a, 21b, the control section 30 resets or restarts the 2nd counter 2. Thus, the data inputted at a transfer speed corresponding to the frequency of the CK2 is converted into a transfer speed corresponding to the frequency of the CK1 and outputted and the data written in a prescribed order in the RAMs 3, 4 is read in a different order at the same time and outputted as the data converted in the transfer order. Thus, the constitution is simplified.

Title: Color image reproducing device
Inventor: OKABE MASAHITO
IPC: G02F1/13
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To reproduce a color image of a high quality by arranging two strings of CCD line sensors on the same substrate by shifting by a 1/2 pixel to obtain sufficient number of data without reducing the size of the pixel of the CCD sensors. SOLUTION: A CCD line sensor 70 is constituted by arranging the two strings of CCD line sensors on the same substrate by shifting by a 1/2 pixel. At the time of reproducing an image recorded by a color filter by using the sensor 70, many pieces of data can be sampled with respect to the color filter without reducing the pixel size of CCD. In addition effective image data is obtained by the CCD included in the pixel of the color filter. At the time of trying to obtain the same number of data as the CCD line sensor by a conventional system as, the pixel of the CCD sensor is required to be smaller than the size of the pixel of the color filter which causes the deterioration of a picture. In addition, the positional precision of assembling is not a problem because two strings of the CCD line sensors are arranged on the same substrate.

Abstract: PROBLEM TO BE SOLVED: To stably carry out automatic measurements for a long term by constituting a power source for a position-detecting part, a propeller part, a water quality data-transmitting part and a control part to be a separate system from a power source for a sensor part. SOLUTION: Primary power sources 9a, 9b, and a secondary power source 9c are provided as power sources for driving parts. The primary power source 9a supplies electricity to a positiondetecting part 1, a water quality data- transmitting part 7, a control part 10 and an SRAM 8, and the primary power source 9b feeds electricity to a propeller part 2. The secondary power source 9c uses a solar battery 9d as a charging source, supplying electricity to a sensor part 4, an instrumentation control part 5, a water quality data-processing part 6, etc., consuming not so large power. In other words, the primary power sources 9a and 9b are used to move the parts when a measurement is not conducted, and the secondary power source 9c is used as a power source for measurements. Power sources of different systems are used for a measuring system and a non-measuring system.  The primary power source 9b is a large power source because the propeller part 2 consumes a large quantity of power.

IPC: B21D31/04
Filed: 1981-10-17
Abstract: PURPOSE:To reduce falling-off of the filled activating substance and to obtain the substrate for  an expansion-type storage battery which has an increased height and in which the filling  amount of activating substance can be increased. CONSTITUTION:The large V-shaped slit part 3a which is set in the interval 2 between the slits  3 and 3 of the contiguous slit line is formed in the middle part of each slit 3. When the elementary plate 1 having such slits 3 in zigzag form is pulled in the direction of width and each  slit 3 is exapanded, a band-shaped substrate A for expansion-type storage battery is obtained  where said substrate A is equipped with the protrusion 6 which protrudes outwardly from the base surface of the elementary plate and has a height h and the V-shaped inner surface 6a, at  one corner part of the rhombic through window 5, namely at each cross point of lattice crosspieces 4 and equipped with a groove 7 having the V-shaped inner surface 7a at the other  corner part opposite to the corner part described the above. Therefore, when the substrate A  is filled with the activating substance in paste form, the contact area with the filled activating substance increases in comparison with the conventional rhombic through window 5 having a  simple form, at the V-shaped inner surface 6a of the V-shaped protrusion 6 at one corner of  each rhombic and at the through window 5 V-shaped inner surface 7a of the V-shaped groove 7 at the other corner, the close holding performance of the activating substance is increased to  that extent, and falling-off can be prevented.

Title: Pulse width expansion circuit
Inventor: TSUKIDATE YOSHIHIRO
IPC: H03K5/13
Filed: 1994-07-18
Abstract: PURPOSE:To prevent a circuit of a next stage from malfunctioning by not outputting an output pulse signal obtained by expanding a pulse width of an input pulse signal when the pulse width of the input pulse signal is narrower than a prescribed width. CONSTITUTION:A delay circuit 20 delays an input pulse signal, and a pulse width detection circuit 21 detects a pulse width of the input pulse signal and outputs a pulse width detection signal only when the pulse width is a prescribed width or over. When an output pulse signal generating circuit 22 receives the pulse width detection signal from the pulse width detection circuit 21, the generating citcuit 22 inverts a potential at an output terminal 22A and holds the inverted potential, and when the generating circuit 22 receives the input pulse signal delayed by the delay circuit 20, the generating circuit 22 restores the potential at the output terminal 22A and holds it and outputs an output pulse signal whose pulse width is expacnded. That is, when the pulse width of the input pulse signal is narrower than the prescribed width, since the pulse width detection circuit 21 does not output the pulse width detection signal, the output pulse signal generating circuit 22 does not generate an output pulse.
