Title: Processing of electrostatic deflecting electrode for camera tube
Inventor: ISHIDA MINORU
IPC: H01J29/74
Filed: 1986-06-16
Abstract: PURPOSE:To enable a desired added twist angle to be provided accurately as a whole by dispersely and additionally assigning pulse number equivalent to a numerator to data number equivalent to a denominator. CONSTITUTION:For example, a twist angle is set to omega=30 degree and NC data number in one pitch is 360 with total number of 1800 as a condition. An increment  theta per data at a twist angle omega is theta=1/60.  thetap in pulse conversion (1 pulse=0.005 degree) is thetap=10/3=3+ 1/3(pulse/data). Where the denominator of 1/3(pulse/data) is a number of data and the numerator number of pulse. Namely, the 1/3(pulse/data) can be realized by sending 1 pulse for every 3 data. Since  thetap=3+ 1/3, an angle that can be obtained with 360 data per pitch by periodically sending 3 pulses 3 pulses 4 pulses is 6 degree or an angle of 30 degree with total of 1800 data. This becomes omega=30 degree mentioned above.

Filed: 1990-05-30
Abstract: PURPOSE:To prolong a lifetime of emission by ranging a composition ratio of BaO/CaO contained in an electron emitting substance fused and impregnated in a porous base within 0.5-1.5 in a molecular weight ratio. CONSTITUTION:A porous base 8 having a pore ratio of about 20% and cut out of a disk-like W powder pressed body is embedded into mixed powder incorporating BaO/CaO in a molecular weight ratio of 0.5-1.5, BaO/Al2O3 in a molecular weight ratio of 3 or more, i.e., BaCO3:CaCO3:Al2O3 in a molecular weight ratio of 4:5:1. The resultant body is heated in two stages at 900 deg.C and 1900 deg.C in a hydrogen atmosphere, followed by cooling. The resultant molten block is ultrasonic-cleaned in pure water at a room temperature. An electron emitting substance adhering to a portion other than pores of the base 8 is removed. A thin film made of an Os-Ru alloy is formed on the porous base, thus obtaining a cathode. Consequently, it is possible to enhance reliability of an emission lifetime of an impregnation type cathode so as to prolong lifetime.

Title: Connector housing
Inventor: FURUICHI KENJI
IPC: H01R13/42
Filed: 1991-05-14
Abstract: PURPOSE:To detect the half-insertion state easily and surely by providing a housing, partition walls and projections so that the projections are elastically bent in the arrangement direction and kept protruded sideward in the half- insertion state. CONSTITUTION:When a terminal 21 is first inserted into a housing 1, the tip section of the terminal 21 pushes back projections 31, 32 at both ends to the right and left, when the terminal 21 sufficiently proceeds, the projections 31, 32 are returned to the original positions by their elasticity. When a terminal 23 is next inserted, projections 33, 34 are pushed back. If the insertion of the terminal 23 is insufficient, the projections 33, 34 are not returned to the original positions and are kept in the bent state. When a terminal 22 is finally inserted, the projection 32 on the terminal 21 side in the complete-insertion state can be bent, however the projection 22 on the terminal 23 side in the half-insertion state is pushed by the tip of the terminal 23 and protruded to the terminal 22 side, thus the insertion of the terminal 22 is hindered. The half-insertion state can be surely detected.

Abstract: PURPOSE:To execute write continuously by using a single head, and also to execute a procedure of erasion-write in an almost real time, by constituting a storage device so that its capacity is set so as to be able to store new information continuously even in a recording period of information. CONSTITUTION:When an optical head 108 completes an access to a recording start position on the first track in which information is to be recorded newly by a control signal from a rotary motor control part 109, information which is recorded already is erased by the first one rotation.

Abstract: PURPOSE:To provide the speech input device which can be improved in recognition rate when used in noise environment, and the speech recognizing device and alarm generating device which use the speech input device as a preprocessor. CONSTITUTION:The output of a bone conduction type microphone 41 is led to a digital filter 43 and equalized by using the output of a contact type microphone 42 which is passed through a delay part 44 as a reference signal. The coefficient of the filter 43 is so adjusted by a coefficient adjustment part 46 so that the difference between the output of the filter 43 and the output of the delay part 44 becomes minimum. Namely, the speech signal gathered by the bone conduction type microphone which has superior noise removing performance, but inferior high-frequency-range characteristics is equalized according to the speech signal gathered by the contact type microphone which has superior characteristics even in a high frequency range, so the speech input device outputs a noise-removed speech signal which has flat characteristics up to high frequencies.
