IPC: E04G1/34
Filed: 1993-08-30
Abstract: PURPOSE:To safely and efficiently install various kinds of building members of plant equipment or buildings. CONSTITUTION:In temporary scaffolds provided with scaffold floors 1, 2 fitted to columns 14 and jointing scaffold floors 6, when the temporary scaffols are used, the scaffold floors 1, 2, 6 are extended to secure a sufficient working space. When building members like beams 16, bracings 17, or floors 18 fitted to the lower columns 14 than the temporary scaffolds are fitted from the upper side, the temporary scaffolds can be folded to make them small in plan and hence, obstruction against erection of the building members can be avoided.

Title: Pad for packing
Inventor: OTAGURO HIROAKI
IPC: B65D81/02
Filed: 1991-08-26
Abstract: PURPOSE:To make it unnecessary to manufacture a pad for packing to a different dimensional shape in response to the variation of the thickness dimension of a plate material, and improve the productivity by making the central piece of a U-shaped pad for packing, which protects the end part of a plate material, stretchable by bending the central piece. CONSTITUTION:A pad for packing 10 is made of a U-shaped corrugated fiberboard to protect the end part of a plate material, and is made to be stretchable by bending a central piece 2. This central piece 2 is bent to be formed into an approximate V-shape at a bending part 2a so that the bending part 2a projects to the inner peripheral side of the U-shape, and is respectively connected to a pair of horizontal pieces 3 at the upper and lower ends. The pair of horizontal pieces 3 are plate shaped members with a rectangular flat shape, and have inner surfaces 3a which are mutually in parallel, and the interval between the inner surfaces 3a can be freely changed by contracting or stretching the central piece 2. Thus, since the interval between the inner surfaces 3a of the horizontal pieces 3 can be changed freely, the pad for packing 10 can be fitted on the end of a plate material even when the thickness of a plate material to be packed is changed.

Title: Electronic musical instrument
Inventor: MATSUDA KAZUNORI
IPC: G10H1/18
Filed: 1993-08-30
Abstract: PURPOSE:To provide an electronic musical instrument capable of reproducing an almost fixed playing state even when a large pieces of playing information are generated simultaneously. CONSTITUTION:When an event representing the playing information generated accoridng to input from a key board and a control panel is performed, each event is stored by separating to a priority event queue or nonpriority event queue according to priority set corresponding to the event in advance. The event in the priority event queue is processed successively(530-540) as far as the event exists in the priority event queue, and the event in the nonpriority event queue is processed(550-560) only when no event exists in the priority event queue(530-NO), therefore, the event stored in the priority event queue can be processed preferentially. Playing can be reproduced stably by setting the priority of the playing information with high significance higher such as key depression, key separation, etc., for the melody playing area of a keyboard.

Title: Rotary electric machine
Inventor: ARAKI SADAOMI
IPC: H02P6/28
Filed: 1982-12-09
Abstract: PURPOSE:To accurately perform a speed control by increasing or decreasing the current command value of a commutatorless motor by a low or high speed switching signal in the amount corresponding to the variation in the torque, thereby minimizing the variation in the torque at the low or high speed switching time. CONSTITUTION:A low or high speed signal generator 17 is set at its output to ''1'' at the low speed time and to a value for supplementing the variation in the torque at the high speed time, and a suitable current command signal is fed to a current limiter 9 by a multiplier 16 without varying the output of a speed control amplifier 8. In other words, the generator 17 for obtaining the output of a low or high speed discriminator 15 does not perform the signal correcting function of the multiplier 16 at the low speed time, and multiplies by the multiplier 16 the output value of the amplifier 8 by the output value corresponding to the variation in the torque of the generator 17 at the high speed time. Accordingly, the armature current can be increased by the current command obtained by adding the current correcting value corresponding to the variation in the torque without increasing the output of the amplifier 8 at the high speed switching time.

Title: Hot blast circulating type cooker
Inventor: ARAHORI YOSHINARI
IPC: F24C15/32
Filed: 1986-09-12
Abstract: PURPOSE:To shorten the rise time of the temp. in the chamber inside and reduce the dispersion in the rise time by a method wherein projecting parts which face heaters and project in the heater side are installed at least at either one wall part of a heating chamber or the wall part of a casing. CONSTITUTION:As projecting parts 15 are installed at the back wall 1a of a heating chamber 1, the back parts of blow-off holes 6, 6 sides in the back wall parts facing heaters 4 are convex. Therefore, the quantity of the hot blast A flowing between the heaters 4 and the back wall 1 is reduced and the quantity of the hot blast B flowing between the heaters 4 and a casing 2 is increased and branched off simultaneously. This variation in the hot blow quantity enables the hot blow A and B to flow in well-balanced condition and the heat from the heater 4 is efficiently supplied into the chamber 1. Therefore, the rise time of the temp. in the chamber inside can be shortened and the dispersion in the rise time can be made smaller. The projecting parts 15 may be installed at the casing 2 side.
