Title: Illuminating device
Inventor: ISHII HIROAKI
IPC: G02B27/00
Filed: 1985-11-26
Abstract: PURPOSE:To switch the highly speedy switch of an illumination device used for a color original reading device by providing plural swayable minute reflecting surfaces composed of plural groups and making different the optical characteristic for respective groups for the luminous flux directed to the illuminated object. CONSTITUTION:A mirror swaying part 13 having the corresponding color filter is successively deflected in the sequence of red, green and blue for one line, and is made incident on a cellfoc lens 45. The mirror swaying part 13 of a light deflecting element 43 can be swayed by the order of a micro-second or below. Thus, since the highly speedy switching changing-over of the illumination luminous flux can be executed, a color original reading device to solve conventional problems can be supplied, and since the switching is not the switching of a light source itself, the life of the light source is prolonged.

Title: Dental handpiece
Inventor: MATSUTANI KANJI
IPC: A61C1/14
Filed: 1990-10-03
Abstract: PURPOSE:To keep a cooling water from leaking within a hand-piece by including a flow control valve which adjusts a valve opening according to a size of a pressure of the cooling water on the secondary side as provided in the course of a path of the cooling water to vary a supply of the cooling water to a cooling water jetting part according to a jetting value of the cooling water from a dental bar. CONSTITUTION:A flow control valve 40 has a valve chamber 41 and a balancing chamber 42 within a core 31. The balancing chamber 42 is arranged on the side closer to a head part 3 than the valve chamber 41 and the balancing chamber 42 is connected to the valve chamber 41 through a communicating hole 43. The valve chamber 41 is linked to a cooling water supply pipe 38 through a communicating hole 44 and a part linked to the communicating hole 43 in the valve chamber 41 forms a valve seat 45 comprising a tapered surface. When a pressure of air is large, a valve opening increases and a larger amount of a cooling water is supplied to a cooling water supply pipe 39 with an increase in the pressure of the cooling water flowing into a chamber 51 of the balancing chamber 42. By the contrary, the valve opening decreases with a smaller pressure of the air and the pressure of the cooling water flowing into the chamber 51 reduces. Thus, only a small amount of the cooling water is supplied to the cooling water supply pipe 39.

Abstract: PURPOSE:To execute stable tracking control at the time of reproducing the optical disk of an ultra-high resolution reproducing system. CONSTITUTION:Wobble pits WP, etc., are formed in correspondence to the servo region SA on a transparent substrate 2 and recording pits RP are formed in correspondence to the data region DA. After a material layer 3 is formed in correspondence to the data region DA on the substrate 2, a reflection layer 4 is formed over the entire surface. The material layer 3 induces a state change partially within a reading-out light spot by the heat of the reading-out light and restores the initial state after the passage of the reading-out light. Further, its reflectivity is changed by the state change. A ternary compd. of Ge2Sb2Te3 is used for the material layer 3. Al having the high reflectivity is used for the reflection layer 4. The reflectivity of the material layer 3 increases partially according to the distribution of the light intensity within the laser spot and, therefore, the reading out of information from the recording pits RP is possible. The sufficient reflected light quantity can be obtd. from the laser spot at the time of scanning the servo region SA by this spot. The stable tracking control, etc., are thus executed.

Filed: 1991-09-18
Abstract: PURPOSE: To collect all elements to the same integrated circuit by providing a voltage-current converter between the output of a comparator and the input of an oscillator and setting a complementary state for a frame feedback time. CONSTITUTION: A phase comparator 41 is placed in a first loop and receives a sub-carrier signal SP and an output signal F of an oscillator 40 and sends a current I1 to the control input of the oscillator 40. A phase comparator 44 receives a reference signal F0 , and the signal F and sends them to a voltage- current converter 45 stored in a capacitor C, and the converter 45 outputs a current 13 proportional to a voltage V to the control input of the oscillator 40. In a re-adjustment stage for the frame feedback time, a signal INH is in the high level to set the comparator 41 to the prohibited state and cancels the current I1, and the frequency of the oscillator 40 is adjusted to F0 by the action of a current I3.  In demodulation except for the frame feedback time, the signal INH goes to a low level, and the comparator 44 is set to the prohibited state, and the voltage V is stored in the capacitor C. At this time, the comparator 41 is in the operating state, and thus all the elements can be collected on the same integrated circuit.
