Title: Optical information reproducing device
Inventor: IGATA TOYONORI
IPC: G11B7/125
Filed: 1988-02-29
Abstract: PURPOSE:To reduce the number of parts by forming integrally a light receiving element for reading the disk information with a monitor light receiving element for fixing a quantity of light of a light source. CONSTITUTION:A light beam 22 from a semiconductor laser beam source 21 is passed through a hole 30 of a light receiving element body 27 and reflected by a half-mirror 23 and then projected onto a disk 25. A reflected ray from the disk 25 is reflected by the back side of the mirror 23 and received by the light receiving element PD1. On the other hand, a part 29 of the light beam 22 is received by the light receiving element PD2 formed around the hole 30 and fed back to the beam source 21 by a negative feedback circuit 20, so as to fix the quantity of stimulating light emission. Since the element PD1 and PD2 are formed integrally with the element body 27, the number of parts is reduced. Moreover, at the time of setting up the element body 27, a light beam 33 from the back side of the beam source 21 is received by the light receiving element PD3, and after finishing an adjustment, the PD3 is taken out. Consequently, the light beam 33 is not reflected at all, thus enabling the beam source 21 to operate stably.

Abstract: PURPOSE:To enable a cartridge to stop stably in a correct and specified position by braking a motor after detecting a loading position or an ejecting position with loading and ejecting sensors. CONSTITUTION:When a loading instruction is inputted to a motor control device C, the decision is carried out as to whether or not the cartridge is in the ejecting position 3 based on detected signals from a loading position sensor 2 and an ejecting position sensor 1. In case of the cartridge being in the position 3, a loading rotation signal is sent out of the device C to the motor M. Then, when it is decided by the sensors 2 and 1 that the cartridge is in the loading position 4, a control signal is sent out of the device C to the motor M, so as to stop the motor M in its rotation. Now, when an ejecting instruction is inputted into the device C, where in case of the cartridge being in the position 4, an ejecting rotation signal is sent out of the device C to the motor M. Then, when it is decided that the cartridge has moved into the position 3, a control signal is sent out to stop the rotation of the motor M.

Title: Line light fiber light irradiator with deformed end part
Inventor: FURANKU SHII JIENOBEZE
IPC: G02B6/00
Filed: 1990-02-23
Abstract: PURPOSE: To obtain a continuous linear light source without using very narrow multilayered optical fibers by deforming approximately circular end faces of optical fibers to approximately rectangular end faces by heating and pressure working to make them linear. CONSTITUTION: Circular end faces 34 of plural relatively loose optical fibers 32 face a light source 16. End faces 38 on the opposite side are compressed by heating and pressure working into a not circular but rectangular continuous light emission part. Light emitted from exit faces 38 generates a uniform output distribution on a linear face with a small number of optical fibers. Thus, very narrow multilayered optical fibers need not be used to obtain a continuous linear light source. Consequently, a light irradiator is obtained which is suitable for generation of a uniform irradiation scanning line on the copy object face of an original platen or the like.

Title: Discharge of air from window intended to reduce amount of consumption of air conditioning energy
Inventor: UGA SHIZUO
IPC: E06B7/02
Filed: 1983-03-18
Abstract: PURPOSE:To reduce the amount of consumption of air conditioning energy by a method wherein in the case of a room provided with a double glass type window, the indoor air is discharged into an air discharge port provided in the upper part of the outside of a room from air intake ports in the upper and the lower parts of the room through the space between two window glasses by using a fan. CONSTITUTION:When the room air temperature T3 is higher than the open air temperature T1 and the temperature T2 in the space 13 between the two window glasses or when the open air temperature T1 is higher than the space temperature T2 and the latter is higher than the room temperature T3, the air intake ports 18 and 32 and the air discharge port 16 are opened and a fan 24 is driven. As a consequence, the air in the upper part of the room is discharged into the air discharge port 16 from the air intake port 18 as shown by the arrow B. In this case, the pressure in the space 13 becomes negative and the air in the lower part of the room is sucked into the space 13 from the air intake port 32 so that an air current A flowing toward the air discharge port 16 generates and the temperature in the space 13 comes close to the room temperature T3. Accordingly, the heating environment near the window during ventilation is kept in a favorable condition and it is possible to reduce the amount of consumption of air conditioning energy.

Title: Roll paper fitting construction
Inventor: ISHII MASAHITO
IPC: G03G15/00
Filed: 1985-03-08
Abstract: PURPOSE:To prevent noise generation caused by intermittent motor operation by forming the shaft supporting part inclined, making its parts other than the top from a friction material, and thereby preventing slack of the roll paper borne by the shaft. CONSTITUTION:If a spool 1 is inserted in a slit 14' formed in a frame 13' from the left as shown by arrow A, the spool 1 is located at Point D before an inclined part 15. If then the roll paper 2 is fed by a feed roller 11, the shaft end 6b of the spool 1 does not glide at Point D owing to friction but rolls on the inclined part 15 and moves to the upper part to reach Point E as upper part support 15b. There is no friction material 15a at this Point E with the mother material exposed, so that the spool 1 continues to glide over Point E. If under this condition the roll paper 2 cut by a cuter 12 is fed back to generate slack, the spool 1 falls down the inclined part 15 by its own weight and rotates reversely in the G direction as the arrow so as to wind the slackened roll paper 2.

Title: Sample observing method
Inventor: WATANABE OSAMU
IPC: G01N1/28
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a sample observing method utilizing an optical reaction by a near-filed light at a portion of the surface of a photosensitive material where a sample to be observed stands by positioning the sample on the surface, and irradiation the area with light. SOLUTION: When an area in a recording region surface including a sample to be observed is irradiated with light, an optical reaction by a near-field light at a portion on a photoreceptor material surface where the sample stands occurs stronger than the optical reaction by the irradiation light at another portion. As a result, the distribution of near-field light generating in the sample can be recorded at a different level from that of circumferential portions, as information corresponding to the optical reaction amount of the material. Accordingly, a conventional C mode or I mode probe is made unnecessary, thereby eliminating the prove scanning time, enabling recording to be completed only with one light irradiation, and generating no problem involving the probe.  Since an observation target is fixed to the recording region of photoreceptor material as optical recording, there is no problem caused by unexpected movement of the target, and a characteristic regenerative observation of observation means is made possible.
