Title: Recorder with ink ribbon discriminating mechanism
Inventor: MURAZAKI TAKUMI
IPC: B41J35/36
Filed: 1987-04-25
Abstract: PURPOSE:To prevent a failure in recorder performances and an unsatisfactory printing which are caused by the use of an ink ribbon other than regulated, by a method wherein, identification information as a judgment key is made invisible, whether it is normal is correctly and rapidly discriminated in an electronic manner, and the use of the ink ribbon other than regular is made impossible. CONSTITUTION:With the output of a signal indicating that a ribbon cassette 1 is loaded, an identification signal (d) recorded in a front reader 8 of an ink ribbon R is read by an identification sensor 9, and whether a judgment reference signal D is in agreement with the identification signal (d) is judged by comparison. If the ribbon cassette 1 is judged to be regular, the identification signal (d) is stored in a memory; if it is judged to be other than specified, a warning is continuously displayed until the ribbon cassette 1 is detached. If the loaded ribbon cassette 1 is judged to be regular, whether a print request signal has been outputted from a command input part N is discriminated. If no, an output of the print request signal is awaited; if already outputted a predetermined printing process is carried out.

Title: Powdery granule storage tank
Inventor: TERADA SATOYUKI
IPC: B65G53/38
Filed: 1980-07-25
Abstract: PURPOSE: To crush bridge formation of a powdery granule in its storage tank, by providing air supply ports to the upper part of a hopper part and air suction means to a discharge port of the hopper part in the powdery granule storage tank comprising a cylindrical part with a powdery granule casting port and the hopper part successively provided to its lower end.  
     CONSTITUTION: A powdery granule is cast into a cylindrical part 2 from a casting port 5 and appropriately discharged onto a case conveyer 18 from a discharge port 14 in a hopper part 3 through a gate valve 17. In case of occurrence of bridge formation when the powdery granule is discharged from a powdery granule storage  tank main body 1, firstly the gate valve 17 is closed, then butterfly valves 12AW12D provided in each of the air supply ports 11AW11D are opened to start an exhaust pump 9. This causes generation of negative pressure in a suction hood 15, then the stream of air is produced between the suction hood 15 and the air supply ports 11AW11D. And permeable pressure loss in a powdery granule layer results in a  pressure difference between the suction hood 15 and the air supply ports 11AW11D, thus the bridge formation can be crushed by said pressure difference.

Title: High frequency amplifier
Inventor: FUJIMOTO YASUHIRO
IPC: H03G3/30
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To suppress spurious in an amplifier circuit owing to power noise by providing a variable attenuator and a control circuit amplifying the noise component of power supplied to a high output amplifier circuit to an appropriate level and inputting it to the variable attenuator. SOLUTION: The control circuit 15 controls the variable attenuator 14. The control circuit 15 monitors the drain voltage of the high output amplifier circuit, removes a DC component by a capacitor, extracts only the noise component of power and inversely amplifies it. A power noise signal which is amplified to the appropriate level and becomes an opposite phase in the control circuit 15 is inputted to the variable attenuator 14. The phase of the variable attenuator becomes opposite to that of power noise with a typical value as a center and attenuation quantity fluctuates. When power noise fluctuates to a '+' side, the variable attenuator operates in a direction where attenuation quantity is increased and power voltage increases in the high output amplifier circuit. Thus, the gain increases.  The effects are compensated, amplitude modulation owing to power noise is suppressed and spuriousness can be reduced.

IPC: H01L21/60
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To provide the mounting device and the mounting method for electronic parts, which can counter the reduction of the mounting space of the electronic parts. SOLUTION: In a mounting device III, the width dimension W1 at a head member 6 of a compressing head 4 is made smaller than the width dimension W2 of a liquid-crystal driver IC2. Therefore, even if a glass substrate 12 of a liquid-crystal panel 10 is arranged in the width direction of the IC20 in close proximity, the glass substrate 12 and the compressing heat 14 are not mutually interfered. Even if the IC20 is brought close to the glass substrate 12 and the mounting space, which is the extending part of a glass substrate 11, is reduced, the mounting of the IC20 can be securely performed by using the compressing head 4.

Abstract: PURPOSE:To efficiently extract carboxylic acids especially in the order of higher concentration by extracting carboxylic acids in an aqueous solution of strong acid formed by Koch reaction, etc., by using a naphthene-based hydrocarbon such as cyclohexane as an extractant. CONSTITUTION:Carboxylic acids are extracted by using a naphthene-based hydrocarbon (especially cyclohexane is inexpensive and preferable) from an aqueous solution of a strong acid in a state where the carboxylic acids are dissolved in an acidic aqueous solution, usually a mixed aqueous solution of sulfuric acid and phosphoric acid frequently used in Koch reaction, an aqueous solution of sulfuric acid or an aqueous solution containing trifluoroboric acid. <=7C tertiary carboxylic acids or carboxylic acids having a naphthene ring in the structure such as 2,2-dimethylpentanoic acid or cyclohexanecarboxylic acid are especially preferable as the carboxylic acids. By this method, the concentration of residual carboxylic acids in a reaction system containing a catalyst can be suppressed low. Consequently, selective ratio of main reaction is improved, side reactions are suppressed, life of the catalyst is prolonged and increase in volume of the catalyst is subdued.
