Title: Magnetic disk device
Inventor: HISHINUMA TOSHIO
IPC: G11B25/04
Filed: 1980-10-24
Abstract: PURPOSE: To remove foreign matter from a disk and to cool it efficiently, by storing a magnetic disk pack in a sealed vessel, and making air in this vessel circulate through a filter.  
     CONSTITUTION: At a position of the outside from the circumferential margin of a magnetic disk pack 1, an air inlet of a filter assembly is opened. This position is in an area where pressure becomes highest. In this regard, since the filter assembly is installed to a cover 6, it is not obstructed by a spindle 10 as in case of installing it to the bottom part of a vessel 2, and an air outlet can be opened in the center part, that is to say, an area where pressure becomes lowest. Accordingly, the airflow passing through a filter member 3 is increased remarkably than before by utilizing the pressure difference by a pumping effect to the maximum, and as a result, dust in the vessel 2 is removed in a shorter time than before.

Title: Recording device
Inventor: HARA MASAO
IPC: H04N9/86
Filed: 1982-08-26
Abstract: PURPOSE:To prevent disorder of synchronism and deterioration in picture quality due to noise by setting the timing of the switching of a selected element within the horizontal blanking period of a compressed color difference signal. CONSTITUTION:A compressor 40 consists of four delay elements 41A-41D and a switching circuit 42 which selects compressed color difference signals, i.e. delay outputs and arrays them successively and alternately is provided behind the compressor. Switching control over outputs of the elements 41A-41D is performed by switching pulses PS generated by a switching pulse generating circuit 70 to set the switching timing in a horizontal blanking period of a compressed difference signal SC, specially right after reference pulse insertion. Consequently, even if switching noises are generated by switches SW1-SW3 during switching, deterioration in S/N due to the switching noises is eliminated.

Title: Dc-dc converter
Inventor: YAMAMOTO SUEYOSHI
IPC: H02M3/28
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To stabilize the charge operation even if the input voltage changes, and enable each battery different in rated voltage to be used as a power source, by arranging the constitution such that a current control circuit shunts the starting current inputted into the base of an oscillatory transistor through a resistor, according to the voltage of the battery power. SOLUTION: A current control circuit consisting of a constant voltage diode 51 and a resistor 52 is connected to a resistor 8 for voltage detection installed at a constant current circuit. The current control circuit decreases the current flow from a constant diode 9 by raising the input voltage. Hereby the higher the power voltage is made the more current flowing into the base of the oscillatory transistor 15 drops and the more peak value of a collector current goes down. Hereby, even if the input voltage changes, the charge operation becomes stable, and it becomes a DC-DC converter advantageous for a flash discharge emitter where each battery different in rated voltage is used as a power source.

Title: Character recognizing device
Inventor: OOKAWA MASAHIRO
IPC: G06K9/68
Filed: 1981-09-21
Abstract: PURPOSE:To improve the recognition rate or the recognition precision without increasing a required time much, by changing the reference in extraction of character features to scan characters again. CONSTITUTION:Characters on an original are converted photoelectrically by a scanner, and the obtained analog signal is subjected to A/D conversion and is written in a memory. The video signal written in the memory is subjected to positioning, namely, one-character segmentation. Features of the pattern described by segmented one-character components of the binary video signal are extracted. For example, alphabet S and number 5 are very like each other but S has a jump in the last, and character S is characterized by having a recess part Q in this jump part. Then, the reference value is made smaller for rescanning, and recess part presence (f) is checked; and when this existence (f) is discriminated, character S is distinguished from number 5. After changing the reference value in feature extraction, characters are discriminated and pertinent characters are extracted while referring to a dictionary, and thus, the increment of the time required for character recognition is restrained as much as possible.

Abstract: PURPOSE: To determine an amino acid in high accuracy, by contacting the specimen liquid to be analyzed with a microbial electrode obtained by immobilizing active cells of nitrifying bacteria belonging to Nitrosomonas genus in the neibourhood of the membrane of a dissolved oxygen electrode, and measuring the output current of the microbial electrode.  
     CONSTITUTION: A buffer solution (carrier solution) 18 saturated with oxygen is flowed through a determination cell 13 with a pump. The specimen liquid is introduced into the flow of the carrier liquid intermittently at regular intervals through an inlet 19. The specimen liquid diluted properly with the carrier liquid is flowed into the determination cell 13 and brought into contact with the microbial electrode 11. The amino acid in the specimen liquid is deaminated by the microbial layer of the electrode, and the produced ammonia is further cxidized consuming the dissolved oxygen. As a result, the dissolved oxygen concentration is decreased, and accordingly the output of the oxygen electrode is also decreased, which is recorded with a recorder 16.

Abstract: PURPOSE:To make the power variation ratio large and to decrease the number of lens elements by using an aspherical surface which decreases in refracting power with the distance from the optical axis as at least one surface among the lens surfaces of a 4th group composed of a single positive or two positive lenses. CONSTITUTION:A 3rd group consists of a positive and a negative lens and the 4th group consists of a single positive lens; and the object-side surface of the 4th group is aspherical and the surface of the 3rd group which is closest to the object side is also aspherical. Thus, the negative lens is arranged in the 3rd group to compensate an on-axis chromatic aberration and a power chromatic aberration sufficiently and this negative lens compensates even a negative spherical aberration. Further, the 3rd group is given sufficient refracting power, the principal point of the 3rd group is set as forward as possible, and a positive lens whose object-side surface is convex is arranged on the most object side to provide two or three positive lenses including the positive lens. The 4th group is used as a focusing group. Consequently, the small-sized lens system which has a high power variation ratio and a large aperture ratio and consists of a small number of lens elements is obtained.
