Title: Transmission type screen
Inventor: KANEKO MASAMICHI
IPC: G03B21/62
Filed: 1990-06-22
Abstract: PURPOSE:To improve the horizontal and vertical directivity of a projected image and image quality by making the relation between the light diffusivity of a lenticular sheet and 1st and 2nd lenticular lenses specified one. CONSTITUTION:The light diffusivity in which haze value H of a material is 60-90% is added to the lenticular sheet 3. The 1st lenticular lens 3a in a lateral direction is formed on the incident surface of the sheet 3 and the 2nd lenticular lens 3b in a longitudinal direction, which is orthogonally crossed with the lens 3b, is formed on the exiting surface of the sheet 3. Then, the ratio D/L1 of the pitch L1 of the 1st lenticular lens 3a to the depth D of the lens 3a satisfies the condition of an inequality I and the ratio of the L1 to the pitch L2 of the 2nd lenticular lens 3b satisfies the condition of an inequality II. The ratio of the pitch of the lens is selected according to the haze value of the sheet material. Thus, the excellent image quality in which the occurrence of moire is restrained is obtained and a light beam transmissivity is enhanced, then the directivity in the horizontal and vertical directions is made large.

Abstract: PURPOSE:To retrieve a desired track stably at a high speed by adopting the constitution such that a tracking element is not vibrated even when a linear motor is moved at a high speed at the coarse retrieval. CONSTITUTION:In case of giving a desired track address to an address input device 77, an information processing controller 78 uses a signal of a synthesis circuit 61 to read a track number with a light beam of a recording carrier 57 located thereupon and sends a direction signal to a signal generating circuit 75. A state observing device 73 estimates a relative position of the element 56 to a carrying base 71 by using a signal of a circuit 56 to drive the tracking element 56, a signal of a circuit 70 to drive a linear motor 69 and a signal of a counter circuit 74 representing the position of light beam on the carrier 57. The estimation signal is fed to the tracking element 56 to avoid the vibration. The circuit 74 counts number of tracks through which the light beam crosses on the carrier 57, sends a coincidence signal to the device 78 to open a switch 76 thereby stopping the motor 69.
