Title: Apparatus for inspecting surface shape
Inventor: KUMASAKA HIROSHI
IPC: G06T7/00
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To highly accurately inspect a surface shape of an object to be inspected with reduced influence due to movement or the like of the object even in a simple structure. SOLUTION: Substantially uniform laser light having a rectangular cross section is shed to a photosensitive drum 4 which is an object to be inspected wherein an angle made between a rotation axis of the drum 4 and a light shed direction is acute. Diffused light is converged by a flat convex cylindrical lens 5 positioned on a normally reflecting light axis for projecting an image by the reflected light on a semitransparent screen 6. A CCD camera 7 picks up this image from behind the semitransparent screen 6 and sends its brightness signal to a processor 8. The processor 8 determines whether or not a surface of the photosensitive drum 4 is good based on whether or not a brightness range is normal or displays an image for making this determination.

Abstract: PURPOSE:To maintain freshness at all times without making the sense of small dull and to prevent a feeling of comfortableness and pleasure from decreasing by controlling the kind, intensity, etc., of aroma on the basis of a physical quantity having 1/f<k> relation with respect to frequency (f). CONSTITUTION:A random generating means A1 consists of a clock oscillator 1, a random signal generating shift register 2, an EXOR gate 3, and a decoder 4 and generates a random signal whose frequency spectrum intensities have the 1/f<k> relation with respect to the frequency (f). The setting of the intensity of aroma is adjusted by the variable resistance of a control means B1 and when an electronic switch 6 is turned ON, a corresponding solenoid 9 is turned ON to supply aroma having corresponding intensity. The random binary number of the shift register 1 is decoded by a decoder 4 to excite a solenoid corresponding to the number. Consequently, the aroma which gives a feeling of natural comfortableness and has intensity with fluctuations is obtained.

Title: Frequency to voltage converter
Inventor: ISHIDA HIROSHI
IPC: H03K9/06
Filed: 1982-07-20
Abstract: PURPOSE:To output a ripple-free converted voltage even when a frequency is low, by generating and outputting the 2nd pulse together with change-point detection pulses regarding an input signal when the interval of the detection pulses is greater than a specific value. CONSTITUTION:A change-point detecting circuit 103a outputs a normal rotation pulse P with a period corresponding to a number of revolution in response to the rising and falling of pulses P1 and P2 which have a pi/2 frequency phase shift corresponding to rotation and the detection of a leading pulse. This pulse P triggers a monostable multivibrator 103b, but it is not reset through a transistor (TR) when the period of the pulse P is long, so the output TS of the monostable multivibrator 103b is still at a high level. Then, a signal ES delayed by FFs 103d and 103c controls a logical gate and when the period of the pulse P is long, a pulse CS delayed by the FF103c is added to the pulse P to increase the pulse width of the frequency-converted voltage outputted from an OR circuit OR2, so that even when the frequency is low, the less-rippled frequency-converted voltage is generated through an LPF, etc.

Filed: 1993-05-28
Abstract: PURPOSE:To prevent a dark current and to prolong a battery life by stopping application of a power source voltage to power source control means by turning OFF an electronic switch after a predetermined time after the switch is opened. CONSTITUTION:When a power source switch 20 is closed, a first power source ON signal PS1 becomes 'H', an electronic switch 23 is closed to supply power to a power source control LSI 13, a power source ON signal PWRON becomes 'L' after a time tau, and power supplying is started. At the time of the power source OFF, when the switch 20 is opened, a switch monitor signal SM becomes 'H', and hence a main control LSI 16 conducts writing of an EEPROM as prescribed and sets a second power source ON signal PS2 to 'L' after a predetermined time T. Thus, the switch 23 is opened, power supplying to the power source control LSI is stopped, and when a power source supply control signal CONT becomes 'L', an operation of a power source 14 is stopped, and an apparatus becomes an unavailable state. The LSI 13 is disconnected from a battery power source 11 by the switch 23, no dark current flows to the power source control LSI, and a battery life can be prolonged.

Title: Method for high density recording of magnetic recording medium
Inventor: ISHIBASHI SHINICHI
IPC: G11B5/02
Filed: 1993-05-28
Abstract: PURPOSE:To prevent generation of diamagnetic field and to improve recording density by recording digital signals in such a manner that the reverse direction of magnerization in a minute area is tilted at a specified angle in a specified angle range to the traveling direction of a magnetic recording medium. CONSTITUTION:A magnetic layer of a disk-type magnetic recording medium 1 has tracks 13. In the track, recording is performed in such a manner that small magnets 14 to be magnetized by a magnetic head in the reversal direction of magnetization perpendicular to the traveling direction of the medium are magnetized in alternately reversed directions. In this method, a demagnetization effect due to diamagnetic field is hardly caused so that digital signals can be recorded as a line of minute magnets having strong reverse magnetization in the track 13. Further, the reverse magnetization width B of small magnets 14 is decreased without depending on the track width T so that the identifying function for tracks can be improved. Thus, the bit density on tracks 13 can be improved without increasing tracking errors during reading recorded data.
