Title: Underwater detecting device
Inventor: UCHIHASHI SHIYOUZOU
IPC: G01S7/58
Filed: 1981-03-10
Abstract: PURPOSE:To make it possible to execute automatic range switching when memorizing and indicating wave-receiving signal in a fish-detecting equipment, etc., by detecting a seabed signal and holding in memory of a signal of depth range in which the seabed signal exists. CONSTITUTION:A wave transmitting/receiving unit 1 transmits an ultrasonic pulse into water on the basis of a trigger a formed every cycle T of a transmitting trigger generating circuit 2, and at the same time, it receives reflected wave. An amplified signal b of an amplifying circuit 4 is treated by A-D conversion 4 and memorized by a memory circuit 5. A signal read out from the circuit 5 is treated by D-A conversion 6 and indicated on such an object as a CRT 7. A seabed detecting circuit 8 slices a signal b at a level Vo and detects a seabed pulse C1 by a seabed signal B1. An FF13 is changed to high level by the pulse C1. A frequency-dividing pulse generating circuit 11 divides frequency in proportion to the cycle T based on the change of detecting depth range. Therefore, content of memory of the circuit 5 is always selected within a limit of signal of depth range containing the seabed signal.

Title: Slide type magnetic head for magnetooptical recording
Inventor: ROPPONGI TETSUYA
IPC: G11B11/105
Filed: 1995-02-23
Abstract: PURPOSE: To improve vertical magnetic field generating efficiency to attain the power saving effect by forming an external leg part having a cutout portion in such a manner that a gap to a recording medium provided opposed to the external leg part is kept within the size of an intermediate led part. CONSTITUTION: A through hole is provided at the lower surface of ahead case 5 and the other external leg part providing a cutout part as a sub magnetic pole forming a pair with the intermediate leg part as the main magnetic pole of the E type core is inserted into the through hole. However, since the cutout part of the other external leg part and one external leg part which is adjusted shorter than the intermediate leg part are abutted to the lower surface of a head cover, the core location is surely fixed. In this case, since at least one external leg part (sub magnetic pole) of the core is formed so that a gap to the recording medium provided opposed thereto is formed within the size of the intermediate leg part (main magnetic pole), the magnetic field generating efficiency can be improved effectively.

Title: Semiconductor surface treating solution
Inventor: KAKIZAWA MASAHIKO
IPC: H01L21/304
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to use repeatedly a chelating agent by a method wherein a wt.% or higher of a specified value of the chelating agent having more than one phosphonate in one molecule is made to contain in a solution, which is formed containing hydrogen peroxide of a wt.% in the range of a specified value and an ammonia of a wt.% in the range of a specified value. SOLUTION: A chelating agent only having more than one phosphonate in one molecule functions as a stabilizing agent for water hydrogen peroxide even if hydrogen peroxide is mixed with an ammonia and is alkalified. That is, the chelating agent having more than one phosphonate in one molecule is made to exist in a solution, which is formed containing 0.01 to 30wt.% of hydrogen peroxide and 0.01 to 30wt.% of an ammonia. When the addition amount of the chelating agent is too little, the complex formation power of the chelating agent to heavy metals is not brought out fully and in the case where contamination is more than expected or the like, the effect of the chelating agent is lessened through. Therefore, it is desirable to add 0.0001wt.% or higher of the chelating agent for making the repeat use of the chelating agent possible as a semiconductor surface treating solution.

Title: Precision correcting circuit for analog-to-digital converter
Inventor: TAKIZAWA HIROSHI
IPC: H03M1/10
Filed: 1981-03-13
Abstract: PURPOSE:To correct an error due to the variation of an A/D converter by comparing an invariably logical true value with a reference voltage, and correcting measurement data. CONSTITUTION:In a microcomputer CPU1, digital values D1-D3 which correspond to previously obtained reference voltages V1-V3 are stored. As measurement is started, voltage levels from reference voltage generators 4-6 are supplied through a changeover circuit 3 to an A/D converter 2 to obtain digital values D1'-D3'. Then, the CPU1 compares the digital values D1'-D3' with the digital values D1-D3 as true values to obtain a correction coefficient alpha. Then, when an analog signal from a sensor 7 is supplied to the A/D converter 2 through the changeover circuit 3, the CPU1 performs correction by using the correction coefficient alpha. Thus, an error due to the variation of the A/D converter is corrected.

Abstract: PURPOSE: To obtain a long-life, superior-characteristic reproducing stylus at low cost in shortening a work time and also polishing only one specular surface while enabing bort etc., to be used by using diamond only for some part of the reproducing stylus where a disk comes into slide contact.  
     CONSTITUTION: An electrode formation surface 10 is formed slantingly atop of the base part 6 of a conductive material while cross at an acute electrode slanting angle γ a perpendicular line in the tip slide contact surface 9 of diamond 7 stuck with buried metallic solder 8, and an electrode part made of a conductive layer in the formation surface 10 and the base part 6 are connected electrically to enable the base part 6 to be used as an electrode base. Since the electrode formation surface provided to the diamond 7 crosses slantingly the center line of the base part 6 at the acute angle, an electrode opening angle α is extremely small even when back surfaces 11a and 11b are formed at an opening angle β at which the diamond never breaks off during polishing, so that the reproducing stylus is wron away, an increase in electrode width appearing in the slide contact surface is less.
