IPC: B43L13/14
Filed: 1991-06-18
Abstract: PURPOSE:To ensure that a variety of skew views by providing a template attachment device for setting freely and fixing the gradient angle of the template and a support device of a circular long shaft recording pen which is introduced in any pattern frame of the template and is supported vertically to a descriptive surface. CONSTITUTION:A template 2 is installed on a template bracket frame 3, then is given a desired gradient angle using an angle gauge 10 and is fixed to its position using a butterfly screw 11. Then a recording pen 20 attached to a recording pen support device 21 is introduced in a desired form frame in the template 2 and a slide plate is closed by a spring holding plate. Subsequently, the recording pen support device 21 is totally allowed to descend with the floating of a float leg and thereby a nib is permitted to come in contact with the surface of a sheet. Further, a desired skew view can be drawn by moving the recording pen 20 along the inner contact form frame of the recording pen 20 under the state that the nib is kept in contact with the surface of the sheet. When a circle in the template is used as a basic pattern, for example, an ellipse representing a skew view is described in a recording form, if a square is used.

Inventor: OGAWA HIDEKI
IPC: G02B5/18
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a new optical system that is excellently corrected in various aberrations such as color aberration in spite of having a large size and a relatively wide viewing angle, by providing the optical system with a refractive optical system symmetric or nearly symmetric with respect to a diaphragm and a diffractive optical system correcting the color aberration arranged in the vicinity of the diaphragm. SOLUTION: This optical system is constituted of a first group 1 constituted of the refractive optical system, a second group 2 constituted of the diffractive optical system, a third group 3 constituted of the refractive optical system, a diffractive optical surface D incorporated in the second group 2, the diaphragm S and an image surface 1. The matter that the diffractive optical surface D is provided in the vicinity of the diaphragm S is preferred in such a nearly symmetrical optical system. Since a passage position from an optical axis of off-axis light is low in the vicinity of the diaphragm S, it acts mainly to spherical aberration and an on-axis color aberration, and it hardly act to off-axis aberration.  Thus, the matter that the spherical aberration of the whole system is corrected excellently by the diffractive optical surface D is possible without nearly affecting the off-axis aberration.

Title: Lens barrel and optical equipment provided therewith
Inventor: TANAKA HIDETOMO
IPC: G02B7/04
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To reduce the driving load of a cam ring and to reduce spatial restriction by using a compact optical detecting means for detecting the position of the cam ring in a non-contact state. SOLUTION: The compact optical detecting means such as a photointerrupter Z36 and a photoreflector for detecting the position of the cam ring 21 in the non-contact state is used. Namely, when a subject distance is fixed and zoom operation is performed, a CPU 45 calculates the subject distance based on a position where focusing is realized from the initial position of a 3rd moving ring 12 detected by a photointerrupter F35 and the rotational angle of the cam ring 21 detected by the photointerrupher Z36, that is, a focal distance. Then, it predicts the position of the ring 12 changed with the variation of the zoom position and drives the ring 12 to the predicted position. In such a case, when an image entering a CCD 37 is out focus, the ring 12 is driven to the focusing position by autofocusing operation.

Abstract: PURPOSE:To prevent the polarity of a voltage across an MOS capacitor from being changed against an AC input signal voltage by using the gate-source capacitance of an MOS transistor and charging a bias electric charge synchronously with the switching operation of a switch so as to apply a bias voltage always to the MOS capacitor. CONSTITUTION:The voltage VB of a bias voltage generating section E is charged to MOS capacitors CM1, CM2 whose gates are connected together through a switch S7 for a prescribed period. An input signal X1 is given to the inverting input of an operational amplifier through a switch S1 and the capacitors CM1, CM2 in series at the next period. Then the voltage acrossing the capacitors is used in a way that the voltage is larger than a threshold voltage VTH. Even when the voltage acrossing the capacitors is changed, the capacitance is unchanged and a stable phase inverting integration device is offered without using any special floating capacitor.

Title: Heating resistor type air flow measuring device, backward flow judging method, and error-correcting method
Inventor: KOBAYASHI CHIHIRO
IPC: G01F1/68
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To measure a flow rate accurately even in pulsation flow by judging the presence or absence of a backward flow based on the maximum and minimum values within a constant sampling time and performing correction. SOLUTION: A pulsation amplitude A=Qmax-Qmin is obtained from the maximum value Qmax and the minimum value Qmin in a memory, and at the same time a tentative average value B=(Qmax+Qmin)/2 is obtained. Then, based on the pulsation amplitude A and the average value B, the ratio A/B is obtained, and it is judged whether a backward flow exists in a suction pipe or not based on the value of the ratio A/B. With the judgment, a specific threshold is provided at the ratio value, it is judged that a backward flow exists when the threshold is exceeded, and it is judged that no backward flow exists when the threshold is not exceeded. When it is judged that no backward flow exists, no correction is made and the value is outputted as an air flow signal.  On the other hand, when it is judged that a backward flow exists, a correction value corresponding to the ratio is calculated and a value that is obtained by correcting a pulsation waveform is outputted as an air flow signal, thus accurately controlling the fuel of an engine accurately.

Title: Sound signal encode system
Inventor: IKEGAMI KIYOSHI
IPC: H04N19/00
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To generate continuous encode signals at a restart of encoding. SOLUTION: An computing element 403 calculates '1535-S' based on a sample number 'S' (that corresponds to time difference between a video frame pulse and a sound frame pulse) which is held by a register 402. An up counter 401 counts one frame cycle in a Dolby AC3 format and divides a clock of 45KHz into 1536 frequency. The counter 401 fetches the '1535-S' from the element 403 when a video frame pulse arrives, counts every clock input up to '1535' and then returns to '0'. The carry at this time is inputted as a clock of a D type flip-flop 404, and when an encode start signal is supplied from a RS-flip- flop 304, the flip-flop 404 supplies an encode ON signal to a sound encoder.
