Title: Local oscillation frequency synthesizer used for tdma system
Inventor: JOKURA ATSUSHI
IPC: H03L7/18
Filed: 1991-07-31
Abstract: PURPOSE:To provide the local oscillation frequency synthesizer which can establish the switch and synchronization of a frequency in a short time and can reduce energy consumption. CONSTITUTION:The TDMA system is equipped with synthesizers 1 and 2 to receive transmitting/receiving channel designation and the designation of another adjacent station from a base station and to respectively obtain frequency synchronization, and a changeover switch 3. The synthesizer 1 is used for synchronizing the frequency of a speaking channel used between a transmitting slot and a receiving slot, and the synthesizer 2 is used for synchronizing a frequency in the case of monitoring the level of the other adjacent station or reading information between idle slots excepting for the transmitting slot and the receiving slot. Thus, since the frequency can be switched and synchronized in a short time without using any high-speed frequency switching synthesizer such as a direct digital synthesizer, etc., the local oscillation part of low energy consumption can be obtained.

Filed: 1985-08-28
Abstract: PURPOSE:To dispense with an ion implantation process for correcting the channel doping quantity due to partial variation of the threshold voltage of a transistor caused by electron ray direct drawing in a wiring process by irradiating all the surface of a semiconductor device with electron rays. CONSTITUTION:A transistor (the source 21, the drain 22, the gate 23) is formed on a semiconductor substrate 1. A metal film 3 for the wiring between the transistors and a resist film 4 for the pattering of the wiring are coated. A required pattern is drawn by electron rays 5 on the resist film 4 and the resist film 4 is developed. The electron rays 7 are thrown onto all the surface of the semiconductor substrate. Then, the metal film 3 is etched by using a resist pattern 6 as a mask. This eliminates the ion implantation process for correcting the channel dope quantity due to the partial variation of the threshold voltage of the transistor by electron ray direct drawing in a wiring process.

Title: Manufacture and apparatus for expandable mineral material
Inventor: HANSU BEAATO FUEERUMAN
IPC: C03B19/10
Filed: 1984-09-12
Abstract: An expanded mineral material suitable for use as a filler, e.g. instead of or in addition to sand or gravel in concrete mixes, is produced by dropping a stream of solid pellets into a rising stream of heated gas contained in a substantially vertical reactor space; the pellets consist essentially of a fusible mineral composition and a latent blowing agent; while falling in counter-current to the gas stream the pellets are heated progressively and expand at least to the point where they are capable to float in the gas stream and are carried in concurrent motion with the gas stream out of the reactor space. This reversal of motion of the expanding particles provides for a substantially self-regulating residence period of the particles in the expansion zone resulting in substantially improved process control and economy.

Title: Sandblast device
Inventor: MISHIMA AKIO
IPC: B24C3/04
Filed: 1987-07-31
Abstract: PURPOSE:To stably and continuously inject a polishing powder toward an object to be polished by moving a position of an air inlet for feeding air into a mixing chamber. CONSTITUTION:A rotary disc 40 is rotated by a motor 41 to rotationally displace a position of a filter 42 formed at a part of the rotary disc 40, thereby continuously moving an air inlet of a compressed air to be fed through the filter 42 into a polishing powder tank 15 in a mixing chamber 2. During the rotation of the rotary disc 40, a polishing powder 12 tends to generally rotate with the rotary disc 40, but the rotation of the powder 12 is hindered by a projection 43. As a result, the polishing powder 12 staying in the tank 15 is widely stirred by the compressed air fed from the moving air inlet, and is dispersed uniformly and sufficiently. Accordingly, even in the case of using a fine powder as the polishing powder, a polishing powder outlet 20 of the tank 15 is not plugged by the polishing powder 12, but the powder 12 is injected stably and continuously toward an object A to be polished in a blast chamber 3, thereby well polishing the object A.
