Title: Multi-focal eyeglasses
Inventor: KOBAYAKAWA YOSHI
IPC: G02C7/10
Filed: 1989-07-10
Abstract: PURPOSE:To eliminate partial division in a lens plane by enclosing liquid crystal in the lens part of a liquid crystal cell, orienting liquid crystal molecules in a constant direction perpendicular to the optical axis of the lens, and preventing light which is incident on the liquid crystal from being polarized. CONSTITUTION:A member 1 is glass which has a concave internal surface and a convex external surface, a member 3 is plate glass, and both members are adhered with each other. The nematic liquid crystal is enclosed in the internal lens-shaped cell part 2 which is formed at this time. Both internal surfaces of the cell 2 are rubbed as shown by lines 7, and consequently molecules of the liquid crystal enclosed in the cell are all oriented in the same direction, so that the nematic liquid crystal is birefringent having an axis in the direction of the molecules. When this lens is used as a spectacle lens, the light incident on the liquid crystal part is unpolarized light because of the absence of a deflecting filter and has two focuses according to a polarizing direction. Consequently, the multi-focal lens whose lens surfaces are not divided partially is obtained.

Title: Communication equipment
Inventor: YAMAMOTO MASAHIRO
IPC: H04L7/10
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To enable a smooth initial synchronization while considering the influence of a frequency leakage on an opposite-side. SOLUTION: A radio communication means A2 is shifted to a radio reception state after an operation is restored and starts a timer A8. A timer A8 measures second time which is previously decided, and outputs the signal of the effect whenever measurement is terminated. A switching means 7 changes over the reception state of a radio transmission/reception means A6, based on a signal which the timer A8 outputs. The switching means 7 changes over the radio reception state of the radio communication means A2 to a standby state, based on the output signal of the timer A8. The switching means 7 waits for the next output signal of the timer A8, receives the signal and changes over the standby state of the radio transmission/reception means A6 to a reception possible state. Thus, a lacked signal is prevented from always being discharged in the air from the radio communication means A2.

Title: High voltage output small-sized transformer
Inventor: KIJIMA SEIICHI
IPC: H01F30/00
Filed: 1989-07-13
Abstract: PURPOSE:To suppress charging of a core, to reduce a leakage current flowing to the core and to decrease the loss of a transformer by forming a plurality of cores from insulating cores in a high voltage output small-sized transformer. CONSTITUTION:Insulating nickel cores 28, 29 are inserted into a bobbin 24 through a spacer 30. A secondary coil 11S is obliquely lap wound and hence the left side part of the coil 11S obtains a high voltage but its right part obtains a low voltage. Here, a capacitive circuit having a bobbin 24, a core 28, etc., is formed at the high voltage part, but since the core 28 is insulating, a circuit current is reduced, and the charging voltage of the core 28 is decreased. This is similar in the low voltage part. Further, leakage currents flowing to the cores 28, 29 are reduced by the insulating cores, thereby reducing the loss of a transformer by the leakage currents.
