Title: Purification of riboflavin-5-phosphate
Inventor: WARUTAA DOOBURAA
IPC: C07F9/547
Filed: 1989-03-31
Abstract: PURPOSE: To obtain the subject compound for e.g. the treatment of vitamin B 2  deficiency diseases industrially advantageously by treating a reaction mixture obtained by phosphorylating riboflavin with e.g. an alkali hydroxide and separating unreacted matter by treatment with an adsorbent resin and precisely purifying it.  
     CONSTITUTION: Water, an alkali hydroxide or a nitrogen base is added to an impurity-containing crude riboflavin 5-phosphate (5'-FMN) obtained by phosphorylating riboflavin, and the mixture is heated to 30-100°C to obtain a 1-5 wt.% homogeneous crude 5'-FMN salt solution having a pH of 4-8. This solution is treated with an insoluble microspherical polymer adsorbent resin (porous polystyrene/divinylbenzene copolymer particles). A 5'-FMN salt from which most of the unreacted riboflavin has been removed is isolated from the obtained solution, and this is precisely purified to obtain the purpose compound salt.

IPC: H01L21/76
Filed: 1987-03-30
Abstract: PURPOSE:To make the breakdown voltage of element isolation and the breakdown voltage between the emitter and the collector of a vertical type PNP transistor sufficiently high, by etching a P-type semiconductor substrate of a region serving as the collector of the vertical type PNP transistor before the formation of an N-type epitaxial layer. CONSTITUTION:A first N-type impurity diffusion layer 3 is formed in a region on a P-type semiconductor substrate 1 where a vertical type PNP transistor is formed, and a first P-type impurity diffusion layers 5,5' are formed in an isolation region from the other element neighboring with the vertical type PNP transistor and in a prescribed region on the first N-type impurity diffusion layer 3. Before an N-type epitaxial layer 6 is formed on the P-type semiconductor substrate 1, a part of the first P-type impurity diffusion layers 5, 5' formed on the P-type semiconductor substrate 1 is subjected to etching. Thereby, the first P-type impurity diffusion layers 5, 5' are restrained from diffusing into the N-type epitaxial layer 6, and so a sufficient base width of the vertical type PNP transistor can be maintained. As the result, the breakdown voltage between the emitter and the collector or the vertical type PNP transistor can be increased.

Abstract: PURPOSE:To record a program searching signal even in an audio tape recorder mode by providing a program searching signal generating circuit which produces a program searching signal at a recording mode setting start time point in the audio tape recorder mode and a releasing time point in a record temporary stop mode. CONSTITUTION:In a video tape recorder VTR mode a changeover switch S3 is kept on and a video signal recording circuit 1 is actuated together with a sound signal recording circuit 2. A program searching signal generating circuit 12 produces a program searching signal (f) in response to supply a recording mode signal (b) and a mute signal (d) from input terminals 8 and 10 respectively. In an audio tape recorder ATR mode an ATR mode signal (a) is supplied from an input terminal 7 to turn off the S3. Then the circuit 12 produces a signal (f) like the VTR mode. A pause mode signal (c) is supplied from an input terminal 9, and the supply of the signal (d) is discontinued when the supply of the signal (c) is stopped. Then the signal (f) is produced. Thus the signal (f) can be recorded even in an ATR mode.

Title: Lead frame material for ic
Inventor: OKAMOTO YOSHINOBU
IPC: H01L23/50
Filed: 1985-04-17
Abstract: PURPOSE:To increase adhesive strength with sealing glass by bringing predetermined ranges on both sides of an Al film on a lead frame and a prescribed range on the back to surface roughness on an average of 1-2mum. CONSTITUTION:The surface roughness of predetermined ranges, which must be brought into contact with sealing glass on both sides of an Al film on a lead frame, and a prescribed range, which must be brought into contact with sealing glass on the back, is brought to a value on an average of 1-2mum. Since the surface roughness of the Al film is also increased and trouble is generated in the connection of an Al wire when surface roughness is augmented, it is preferable that surface roughness is brought to 2mum or less. Since electrodeposition is started from a fine projecting section on the surface and solder does not electrically deposit in a recessed section sufficiently on the execution of electric solder plating to an external lead after the completion of packaging when the ranges are not limited, it is undesirable that the ranges are not restricted.

Title: Rotary magnetic head drum device
Inventor: UMEHARA HIROSHI
IPC: G11B5/53
Filed: 1990-03-27
Abstract: PURPOSE:To eliminate crosstalk components (noise components) and to prevent the deterioration in reproducing image quality by successively erasing the overlap regions of recording tracks formed by a rotary magnetic head by means of respective rotary erasing heads. CONSTITUTION:The overlap regions (5)-(6)-(3)-(4) of the respective recording tracks formed are generated if recording is executed by at least a pair of the rotary magnetic heads R1, R2 having the track width wider than a track pitch. The rotary erasing heads E1, E2 can erase the regions (5)-(6)-(3)-(4) among the recording tracks formed by the preceding rotary magnetic head R1 and, therefore, the overwriting of the recording by the other rotary magnetic head R2 set at the angle reverse in the azimuth angle with the preceding rotary magnetic head R1 is obviated. The problem that the crosstalk components occurring in the overlap regions (5)-(6)-(3)-(4) are included in reproduction signals is eliminated in this way.

Title: Life forcasting method and maintenance and inspection method for ceramic structural parts
Inventor: YASUTOMI YOSHIYUKI
IPC: G21B1/17
Filed: 1994-04-19
Abstract: PURPOSE:To enable life forcasting and maintenance and inspection for ceramic structural parts to be carried out by applying induced current to the surface of a ceramic structural part or a conductive circuit provided in the vicinity of the aforesaid surface, and thereby detecting change in voltage in a tested area. CONSTITUTION:When a conductive circuit 3 is provided for the surface 12 of a specimen 2 composed of ceramics matrix, or for the vicinity of the surface so as to allow AC current to be applied, current density becomes greater at the surface 12 located outward than that at the center section, and a skin effect 14 generated by induced current by the AC current thereby reaches the surface layer of the specimen 2. When the specimen surface 12 is cracked 10, the depth of the skin effect 14 is changed, voltage is accordingly changed, therefore the measurement of change in voltage and comparison with a threshold value make those possible such as life forcasting, life diagnoses, and maintenance diagnoses. In this case, even if there exists any area interfering with a skin effect 14, detection accuracy can however be enhanced with the aforesaid area corrected by a controller.

Abstract: PURPOSE:To prevent a relative motion of a reel and a brake by providing a protrusion protruding so as to cover the flange section of the reel at a contact section of the reel and the brake. CONSTITUTION:A brake 4 is rotatably attached to a shaft 1a disposed in a tape cassette 1, its end section 4a engages with a tooth 3a of a reel 3.

Title: Method and instrument for measuring stability in radar transmission/reception
Inventor: ANDORE PEIRA
IPC: G01S7/40
Filed: 1990-03-28
Abstract: PURPOSE: To enhance the quality and accuracy of measurement by measuring a voltage signal from a radar receiver in the first step and regulating the amplitude and phase of an additional signal in the second step thereby measuring the fluctuation of a corresponding voltage signal. CONSTITUTION: The measuring apparatus comprises a measuring unit AM receiving signals I, Q from the phase detector in a receiver RE, and means for injecting a specific additional signal SS into the receiver RE. The unit AM performs measurement at a significant moment of time when the effect of fluctuation of the signals I, Q is inevitable. The amplitude and phase of the additional signal SS generated from a generator GSS are regulated so that the stable parts of the signals I, Q are substantially canceled and the signal SS is superposed on the receiving signal in order to sustain the fluctuation from one period to another. Consequently, fluctuation of the signals I, Q approaches to zero thus realizing a highly accurate high quality measurement.
