Title: Ventilation fan for duct
Inventor: TSUKITARI YUJI
IPC: F24F7/10
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To enable a motor for a blower to be fixed without generating any vibrating sound. SOLUTION: This ventilation fan is constructed such that a motor 15 for a blower has a fixing piece 25 protected at a flange section 24 and the fixing piece 25 is fixed with screws 29 to a main body frame 13. In this case, the surface of the main body frame 13 for fixing the motor 15 is provided with an inclination 27 directed toward the fixing direction of the motor 15 from its central side to an outward side, thereby the extremity end of the fixing piece section 25 of the motor 15 is spaced apart from the main body frame 13, so a so-called 'tip-contact' is eliminated and instead a flange part 24 other than the fixing piece section 25 of the motor 15 is abutted against the main body frame 13 and this may prevent a repetition of contact and spaced-apart motion from the spaced-apart state with the main body frame 13 from being carried out.

IPC: G01K7/24
Filed: 1984-01-10
Abstract: PURPOSE:To make it possible to perform A/D conversion, by using parts of a resistor and a capacity as an interface between a thermistor and a microprocessor. CONSTITUTION:A microprocessor 1 is provided with a signal generating circuit, which generates a reference rectangular signal (a) and guides the output from an output terminal 4. A thermistor 2 is connected to the terminal 4. The rectangular waveform, which has passed the thermistor 2, is imparted to an input terminal 5 and received by the processor 1. A capacitor 3 is externally connected between the terminal 5 and the ground potential. The potential at the connecting point B between the thermistor 2 and the capacitor 3 is changed as a signal (b) in accordance with the value of the time constant RC, which is determined by the resistance value of the thermistor 2 and the capacity of the externally attached capacitor 3. The potential at the point B is inputted to the processor 1 and compared with a preset threshold level Vth. A time-delayed signal corresponding to DELTAt shown by a signal (c) is formed. The delay time DELTAt of the pulses in the signal forming periods as shown by (a) and (c) depends on the resistance value R. By counting DELTAt by the processor 1, the resistance change is converted into a digital value.

Abstract: PURPOSE:To stabilize the frequency of oscillation, by phase modulating laser light emitted in one direction with a frequency of fm, mixing it with light emitted in the other direction to convert the same to fm+DELTAphi, obtaining DELTAphi based on laser noise and servo controlling the operation of the laser with this output. CONSTITUTION:Light from one side of a laser 11 is caused to enter into a detector 17 by a half mirror 13, while light from the other side of the laser is phase modulated by sawtooth waves having a frequency of fm from a signal source 16 and caused to enter into the detector 17 through the half mirror 13. These inputs are superposed and optical frequency component is removed therefrom so as to produce an output of fm+DELTAphi including the phase change DELTAphi based on laser noise. The phase of this output is compared with that of the output from the signal source 16 by a phase comparator 18 to obtain an output DELTAphi(t). This output is supplied to a servo circuit 20 through a low-pass filter 19 so that a control signal is generated to drive the laser 11 by a drive circuit 21 and so that a temperature controller 23 controls the temperature condition for operation of the laser so as to fix it based on controlling characteristics of a PID circuit 22 by means of a Peltier element 24. By maintaining DELTAphifixed, fluctuation in optical frequency can be obviated and the output spectrum is narrowed.

IPC: G06K9/46
Filed: 1992-01-14
Abstract: PURPOSE:To make it possible to recognize also characters written in the running hand, to prevent operability from being remarkably deteriorated due to the increment of recognizing processing caused by the increment of dictionaries and to improve a recognition rate. CONSTITUTION:A pen speed detecting part 20 (or an average stroke length detecting part 30) detects a pen speed (or average stroke length) and judges whether the pen speed (or average stroke length) is rapid writing or polite and slow writing based upon a certain threshold. Characters coincident with running-hand characters previously written in a character dictionary is applied to recognition processing with priority based upon the running-hand character degree judging result of the detecting part 20 (or 30). A parameter corresponding to the number of pictures which is previously set up in each number of pictures is corrected by the running-hand character degree. Consequently the quantity of recognizing processing can be reduced due to the reduction of useless processing and the recognition accuracy and the recognition rate can be improved.

Title: Electrode and its manufacture, and secondary battery with it
Inventor: MATSUDA YOSHIO
IPC: H01M4/525
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To manufacture a secondary battery excellent in the discharge capacity characteristic at a high output by specifying the ratio of the volume of the portion at the specific thickness or below from the surface of an electrode material against the volume of the electrode material having the prescribed thickness or above in a sheet-like electrode. SOLUTION: The discharge capacity for the unit weight at a high output is decreased when the thickness of an electrode material becomes 20μm or above as shown in the Fig. The thickness of the electrode material effective for the high-output discharge capacity as a battery is 40μm as shown in the Fig. When the thickness of the electrode material is 20μm or above and an electrode has the structure satisfying the relational expression (X/V)×100>=60%, it is suitable for a high-output discharge, where V is the volume of the electrode material and X is the volume of the portion at the thickness of 40μm or below from the surface of the electrode material. When the electrode surface is made an irregular face, the electrode surface area is increased, the ion diffusion into the electrode is accelerated, and the discharge characteristic can be further improved.
