Abstract: PURPOSE:To make counting operation of parts quick and to prevent erroneous weighing owing to errors in counting by providing two resolving powers to a weight detecting means and detecting weights by using the respective resolving powers according to the operations of a unit weight setting means thereby detecting weights. CONSTITUTION:The output of a weight detecting means is applied to an amplifier in a casing 1, and the gain of the amplifier is changed over the two stages. While many parts are counted, some pieces of parts are placed on a tray 11, and the number of said parts is inputted with switches 5 and the higher gain of the amplifier is selected, thus the total weight of the parts on the tray 11 with the higher resolving power is measured. When the operator pushes a number setting button 7, the total weight thereof is divided by the number of parts on the tray 11 and the weight of one piece of the parts is displayed in a unit weight display part 3. Thereafter the amplifier is changed over to the low gain, and when a large quantity of parts are placed on the tray 11, the total weight thereof is displayed on a weight display part 2. The total weight thereof is divided by unit weights and the results thereof are displayed as the number on a display part 4.

Title: Retransmission control method/retransmission controller
Inventor: SATO KAZUMI
IPC: H04L1/16
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To suppress the amplitude of an OFDM(orthogonal frequency division/ multiplex) time waveform, to improve transmission average power, to reduce transmission errors and to improve throughput. SOLUTION: When a retransmission request is generated, an OFDM reception part 3 gives a retransmission request signal to a scramble control part 2. The scramble control part 2 changes the scramble group of the scramble part 1 into a scramble group before retransmission. Thus, the time waveform of the OFDM symbol by a retransmission data group from a modulation part 4 changes before and after rctransmission and there is possibility that the average power of a transmission signal becomes high. Thus, possibility that transmission errors are reduced by retransmission becomes high and throughput improves.

Title: Automotive sun-roof structure
Inventor: TAKEDA YOSHIMITSU
IPC: B60J7/00
Filed: 1992-01-10
Abstract: PURPOSE:To provide an automotive sun-roof structure where resistance force being imparted to a sunshade becomes constant at all times. CONSTITUTION:This sun-roof structure is one that disuses such a structure as making head lining 17 come into contact with a sunshade 16 and has solidly formed a rising part 15 in contact with a lower soft outer surface part 16a of the sunshade 16 at constant frictional force, in an inner end of a frame 14 instead. Therefore, since a rail part 7 (guide rib 8) and the rising part 15 both come to a state of being installed in the frame 14 itself in consequence, any error is hard to be produced in a positional relationship between both of them, thus the constant positional relation is securable at all times. Accordingly, the rising part 15 formed so as to be made contact with the lower soft outer surface part 16a of the sunshade 16 at constant frictional force maintains its constant frictional force at all times.

Heated air generated in the solar heat collecting section A in the roof 5 is collected by the heat collecting box 21, and sent into the air flowing space 33 of a floor 30 through a duct 23 by a blower 25. Warm air in the air flowing space 33 is given moisture by a humidifying pan 40, and blown off into an indoor section C from a warm-air blow-off port 34, thus warm-air heating is obtained. Accordingly, air collecting heat from solar rays can be utilized effectively.

CONSTITUTION:When atmospheric pressure is reduced in the high land, the bellows 3 of the altitude compensating valve 11 is expanded to close an releasing port 14. Accordingly, a diaphragm chamber 17 is kept in a high vacuum, as a result, a diaphragm 15 and a valve 18 are lifted up against a spring 16 and atmosphere from a filter 12 is introduced into the altitude compensating air paths 8, 10. According to the introduction, air is introduced into the fuel of fuel paths 5, 6 and the air-fuel ratio is thinned. In this case, a high vacuum is introduced into the diaphragm chamber 27 when the opening degree of a throttle valve 3 is low, for example, and the valve 29 is lowered against the spring 26 to close an atmosphere supplying path 22b. According to this method, the excessively thin air-fuel ratio in case the amount of suction air is small, for example, may be prevented and the optimum air-fuel ratio may be secured.
