Title: Antenna selective diversity radio equipment
Inventor: AKAIWA YOSHIHIKO
IPC: H04B7/06
Filed: 1989-05-31
Abstract: PURPOSE:To facilitate miniaturization and to allow the radio equipment to cope with fading by using an antenna selected by the antenna selective diversity for a transmission antenna at the reception. CONSTITUTION:An information signal obtained from an antenna having a high signal level among signals received from two antennas is used as a reception signal. In this case, the result of comparison by a comparing means 153 is stored in the storage means 142 of a transmission section 14. In the case of sending from a base station (stationary station), a transmission signal from the transmission means 141 of the transmission section 14 is sent from one of antennas 11, 12 via a switching section 13. In this case, a reception selection control signal generated from the comparing means 153 of the reception section 15 is stored in the storage means 142 of the transmission section 14, the switching section 13 applies switching depending on the stored content at the transmission and the selected antenna is used as the transmission antenna. Thus, the miniaturization of a radio equipment of a mobile station is facilitated and the equipment copes with fading.

Title: Separation apparatus for walking animal
Inventor: KUSUBE AKIRA
IPC: A01K15/04
Filed: 1993-06-10
Abstract: PURPOSE:To obtain a low-cost separation apparatus for a walking animal by reducing load on an actuator driving swinging gates. CONSTITUTION:The separation apparatus for a walking animal is provided with swinging gates 3A,3B and a gate opening and closing means C. The front view of the walking animal is shielded with the swing gates in entirely closed state. Each of the gates is freely rotatable around a vertical shaft. The gate opening and closing means C switches the gates between an entirely closed state and an intermediate state of the entirely closed and the entirely opened state and allows the walking animal to pass the gates in the intermediate state. This means C is composed of a checking member, which can fix the gates 3A,3B to the opened state and switches the gates between a gate checking and a check releasing position by a vertical movement in the direction of the vertical shaft, a cam member, which shifts the checking member from the checking position to the check-releasing position and a stopper, which prevents, by hitting a blocking body, the rotation of the gates 3A,3B from the intermediate to the entirely closed state actuated by a returning power in the reverse direction against the rotation of the blocking body, which rotates in one direction together with the checking member.

Title: Dropout compensation device for video equipment
Inventor: YASHIRO YOSHIKAZU
IPC: H04N5/953
Filed: 1989-05-31
Abstract: PURPOSE:To attain accurate dropout compensation by outputting a video signal inputted from a time axis correction means when an identification signal detection means does not detect the identification signal and outputting a video signal inputted from a delay signal generating means when the identification signal is detected. CONSTITUTION:After jitter of a video signal outputted from an identification signal insertion circuit 38 is eliminated by a time axis correction means 44, the resulting video signal is subject to the detection of the presence of an identification signal by an identification signal detection means 47. When no identification signal is detected, a signal changeover output circuit 46 outputs a video signal without jitter outputted from the time axis correction means 44 as it is. When the identification signal is detected by a comparator 48, the signal changeover output circuit 46 is used and the video signal from which jitter is eliminated by the time axis correction circuit 44 is replaced with a delay video signal retarded by 1H with respect to the luminance information by a delay signal generating circuit 50. Thus, accurate dropout is compensated.

Title: Manufacture of semiconductor device
Inventor: FUKUZAWA TAKESHI
IPC: H01L21/027
Filed: 1991-06-11
Abstract: PURPOSE:To make it possible to form a fine resist pattern by reducing its process coefficient by a simple method. CONSTITUTION:A resist is coated on a semiconductor substrate 2 with an appropriate thickness. Then, according to a usual process, the resist is exposed and developed in a water solution to form a desired resist pattern 4. Subsequently, the water solution and others used for the development are removed. A heat treatment is performed. The heat treatment here is not only aimed at dewatering, but also at deforming the resist. In this case, the heat treatment after the development is given at a temperature higher than the thermal stabilization temperature of the resin which forms the resist, 140 deg.C, for example. As clear from the resist pattern 4, the edge corners of the expanded resist pattern 4 are rounded to make the side walls of the pattern round. A deformation of the kind contributes to shortening the dimension of the interval between the resist patterns, thus effectively act on the shortening of the resolution.

IPC: B01D17/022
Filed: 1994-05-17
Abstract: PURPOSE:To enable rapid attachment and exchange of a filter and to enhance the working efficiency by inserting a window frame-shaped frame material into a square cap-shaped filter, and attaching it freely slidably in the vertical direction under guidance of a guide groove in an oil adsorption tank. CONSTITUTION:The frame material 6 made of metal and provided with a square window 7 in the inside by boring is inserted into the filter 5 which is formed by laminating two sheets of square filter clothes and sewing or heat-fusing both side edges and the bottom edge in a state that the upper side is opened, and both are integrated into one body. This is inserted into the guide groove 8 formed by using a L-shaped flange 2b on a side wall 2a of the oil adsorption tank, and then attached freely slidably in the vertical direction. Thus, attachment of the frame material 6 to the filter 5 can be remarkably simply performed only by inserting the frame material 6 into the inside of the filter 5 having a square cap-shape. Also since this product is attached by inserting it into the guide groove 8 in the tank so as to fill a gap by the elasticity of the filter 5, leakage of oil from the gap can be surely prevented.
