Title: Speed controller for dc brushless motor
Inventor: OKADA YASUHIRO
IPC: H02P6/182
Filed: 1990-10-19
Abstract: PURPOSE:To sustain the rotational speed of a motor at a constant level by setting the voltage drop due to the load current flowing through a motor coil equal to the voltage drop of a first resistor thereby equalizing the applying voltage of motor and a reference voltage. CONSTITUTION:When the rotational speed of a DC brushless motor fluctuates due to fluctuation of load, voltage induced in the motor fluctuates to cause fluctuation of voltage Vo. The fluctuation is compared through an error amplifier 15 with the reference voltage of a reference voltage supply 14 and the output from the error amplifier 15 is provided to an output transistor 17 in order to control an output current Im. When - input terminal of the error amplifier 15 is connected with second terminal (b) connected with the collector of the output transistor 17, voltage is fed back negatively and both input terminals of the error amplifier 15 operate with identical voltage. According to the constitution, rotational speed of motor can be sustained at a constant level.

Title: Electronic musical instrument
Inventor: IKETANI TADAHIKO
IPC: G10H1/053
Filed: 1991-10-02
Abstract: PURPOSE:To synthesize various kinds of musical tone without increasing a hardware and a memory newly by reading out information which is to be under the control of a musical tone synthesizing means and using it by a control means. CONSTITUTION:From a sound source chip constituting a musical tone synthesizing circuit 11, each data can be delivered separately to a central processing unit(CPU) 3. To put it concretely, a sustain rate and a damp rate stored in a waveform storage circuit (ROM) 10 attached to the sound source chip can be delivered to the CPU through an interface. In such a state, when a state of a damper pedal of an operating piece 6 is varied, the CPU 3 reads out and calculates each data and calculates a release rate, and delivers a result of calculation to the musical tone synthesizing circuit 11. In the musical tone synthesizing circuit 11, it will suffice that an envelope waveform is generated in accordance with the delivered release rate, therefore, a burden for the processing does not increase, and also, it becomes unnecessary to prepare a new hardware.

Abstract: PURPOSE:To secure a shank section easily and quickly, by arranging a displacable fixed member which is pressure fitted to a member to be secured through the pressure in a fluid pressure chamber onto the circumferential face of the annular fluid pressure chamber. CONSTITUTION:Shank section 19 of a punch holder 17 is inserted into a fixed member 23 arranged on the inner circumferential face of a shank fixing hole section 21 of a ram 9 and working fluid is fed through an oil path 29 into a fluid pressure chamber 27 so as to deform the inner diameter of the fixed member 23 resiliently as shown by dash and lot lines thus securing the punch holder 17 to the ram 9 through the shank section 19. When the working fluid is discharged from the fluid pressure chamber 27, the pressure in the fluid pressure chamber 27 lowers to recover the fixed member 23 into original shape thus releasing the shank section 19. Since not tightening bolt is required when the shank section 19 is mounted/dismounted, the mounting/dismounting work can be simplified.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject composition capable of removing stains, especially hibitane, which are difficult to be washed off with alkali washing agents, by using both an organic phosphonic acid-based chelating agent and an organic carboxylic acid and satisfying specific conditions. SOLUTION: This washing pre-treating agent composition for laundries contains (A) 6-60 wt.% of an organic sulfonic acid-based chelating agent (for example, 1-hydroxyethane-1,1-diphosphonic acid or ethane-1,1,2-triphosphonic acid) and (B) 5-40 wt.% of an organic polybasic carboxylic acid (preferably citric acid, malic acid or succinic acid), and has pH 3 at 25 deg.C, when converted into a 1% aqueous solution. Thereby, special stains, especially hibitane, which are difficult to be washed off with alkali washing agents, can synergistically and effectively removed in the washing processes of linen supply industry. When the washed article is then brought into contact with sodium hypochlorite, the article is not colored. It can also be expected that even the whiteness of the article darkened by repeated washing treatments, or the like, is improved.
